• Windows updates fails, get "Error 1327 Invalid Drive/M" error when trying to install updates by using the stand-alone packages.

  Original title: I deleted the files from automatic update and windows update keeps trying to install

  I've done an update for a long time on an old computer unused spare XP and Windows Update said that he had to update a large number of files, so I have left to download and install.  Once the 45 updates completed, I rebooted as instructed and proceeded to clean a lot of old data.  Apparently I deleted (7) files for Office M/S that must be installed, because the Winows Update icon in the status bar telling me I had 7 sto update to install.

  Now Win Update always tells me that the files should be updated and starts the process, telling me that they are already downloaded, but it fails every time because they are not where they should be, as I deleted them without meaning to.  How can I do the update for these startup files, or where can I get the appropriate files to allow the update work properly?

  Yes, I know it was stupid, but this is the frist time that I asked for help from Windows 3.1, so I don't feel too bad.

  I have download the individual Ko * .exe files support, but get an error 1327 Invalid drive / M error whenever I try to install one of them.

  Thank you

• Code 80070241 in Windows update and "Windows cannot verify the digital signature for this file" when you try to run any program.

  Windows Update has appeared today when we started one of our machines, informing us that there are some installed updates. After reviewing the updates, we clicked on the "Install now" button, and immediately, it failed with the above error code.

  I tried to run regedit a reason unrelated, and it came with a dialog box error with "Windows cannot verify the digital signature for this file. A recent hardware or software change might be installed a file that is signed incorrectly or damaged or maybe it's a malicious software from an unknown source. »

  After researching here and elsewhere on google and did not find anything suitable, put us in the Win7 disk, recovery tools and tried to go back to a previous system restore point (3 days).

  The restoration went well, restarted, but the problem persists.

  Then, we just tried to install anti-malware software, but when trying to run the installer, we get a different error message indicating 'ShellExecuteEx failed; Code 577 "and then the same message on the verification of the digital signature.

  The computer is running fine all yesterday and has worked very well since just after the new year when he has been upgraded to Windows 7. No material changes have been made, and no software changes were made by users in the course of last week.

  The computer is an AMD Athlon II X 4 with 4 GB of RAM on a motherboard Asus M4A78-EM, linking a 64 GB SSD, with a 250 GB drive SATA data/programs. GPU is a Nvidia 260, and it has a CD and DVD player as well. It is connected to our router using the gigabit ethernet interface motherboards.

  It was under windows 32 - bit XP SP3 up just after the new year. When we put in place the new SSD to replace a hard drive older than we have did a new install of XP (slipstreamed with SP3) and then used the upgrade 32-bit W7 Home premium DVD version to upgrade the system. Since then, the system runs flawlessley.

  On the machine is MS office XP, Firefox 3.6.3, AVG 8.5 and a few games such as the Turbine DDO.

  The main user account used to try to solve these problems and to run Windows Update and try installing programs is a member of the Administrators group.

  Firefox works fine, serve, and he plays the games installed very well also. AVG reports to date, with no problems and has detected no threat.

  However, try to view the registry with regedit, or start Viewer event or compmgmt.msc that all do appear the message "cannot verify the digital signature.

  ***************************************************

  Can anyone offer an opinion on what might be wrong with this facility please, and how we could do to solve?

  Cannot run chkdsk/scandisk as he bought the message "cannot verify the digital signature" etc etc.

  This morning, the machine began to behave differently - stop playing back badly, refused to start Device Manager, open Control Panel correctly etc.

  So, I reset the BIOS to boot from the CD-ROM, slapped XP SP3 in reinstalled, then upgraded to Win 7 again.

  Still have no idea what caused the problem, but it seems to be gone now - reinstalled the same applications, AV / programs anti-malware, games, etc and everything seems to go fine now.

• Update Win7 failure: error control of digital signature on applications

  I just upgraded my satellite L300 with DVD Toshiba Vista Home premium "s (Dutch version).

  Step 1: update Toshiba DVD deleted all drivers as promised
  Step 2: Windows 7 Home premium Upgrade DVD installed without problem.

  Step 3: Upgrade Toshiba DVD won't start help following (translated from Dutch) error:
  Can't control the digital signature for this file.
  A recent hardware or software change has probably installed a file with a wrong or damaged digital signature...

  Apart from some basic Windows (IE) programs I can't run, install, or remove all other program-always this error...
  Other utilities (wifi for example) just give the message they encountered an unknown error...

  I tried to update some drivers on the Toshiba site but not a downloaded file monkey runs... (all with the same digital signature error)

  What now?

  Edit:

  I got, I think, to install the drivers of Toshiba in safe mode, but many programs fail to run, install or remove even...
  anything that gives the signature error... (ccleaner, revo uninstaller, also all the Setup files downloaded after installation of 7)

  Touchpad will freeze now and if often, leaving only Ctrl-Alt-Del to reboot the computer

  So apparently no one can help me...

  I found a solution to disable the verification of digital signature in Windows 7, but for that you have to open CMD as administrator.
  Guess what, same CMD refuses to open, because it does not recognize the digital signature...

  How to turn off this thing until I throw my PC in the trash...

• Error: "Windows cannot verify the digital signature for the drivers required for this device (Code 52)"

  Original title: Wireless cannot verify the digital signature for the card driver from son - after an automatic update of the software.

  We downloaded an automatic update of our HP Pavilion laptop running Windows 7.  This disabled somehow the wireless network adapter.  Readings of the error; "Windows cannot verify the digital signature for the drivers required for this device.  A recent hardware or software change might be installed a file that is signed incorrectly or damaged, or that might be malicious from an unknown source. (Code 52) ».  We tried 2 system restore - problem persisted.

  I solved this problem to roll back the driver to that before the driver that is currently installed.  The wireless activated immediately when done.

• The laptop recovery Toshiba Satellite L505-S5997 problem error: Windows cannot verify the digital signature for the drivers required for this device

  I have a Toshiba Satellite L505-S5997 computer laptop and my hardrive recently crushed, impossible to restart.  I installed a SEAGATE 500 GB/sata/GO 16 MB of Cache, 7200 RPM hard drive. I ordered recovery for the computer disks and many of the drivers will not update or install without error that tells me that "Windows cannot verify the digital signature for the drivers required for this device.

  Are you sure that the original problem was caused by a failure of the HD, did you test that the hd with the utility bootable disk from audit?

  As if you reinstalled to a new HD using that the required all defined recovery Tosh disk drivers would have been installed in this process.

  Assuming that Tosh then rebooted successfully after recovery, windows update would have run some important updates automatically. If that failed then it would seem that something is happening with your system.

• The digital signature does not not after 11.0.09 update.

  Hello

  I use Adobe Acrobat Pro XI at the office and was able to use the digital certificate provided by my company and stored in the Windows certificate store to digitally sign PDF documents. After the update (11.0.09) that has stopped working; When I try to sign a document, I'm invited to create a digital ID or choose an existing one from a file; A digital ID for roaming, accessible through the server; A device connected to this computer. However, I can't use existing ID which is always available in the Windows certificate store and used to work before.

  (The same thing happens with the digital signature in Adobe Reader after the update).

  Has changed nothing about how certificates are used for digital signatures with this last update?

  Thank you.

  Kind regards
  Cornel.

  Take a look at my question. Possibly related: can use GoDaddy certificate to sign into Microsoft Office Word 2010, but not in Adobe Acrobat XI 10.0.09

• Second digital signature invalid one

  Hi all

  I'm having some trouble adding a second digital signature to an already digitally signed PDF file. The library that I use to manage PDF files is open source, so I change the PDF files programmatically. The first PDF I produce, PDF1 (PDF with a signature), has a valid digital signature. The second PDF file I produce, PDF2 (the PDF file with two signatures), has the second marked signature as valid, but the first as not valid with the following error:

  Error during signature verification.  
  Unexpected byte range values defining scope of signed data.
  Details: The signature byte range is invalid
  

  I have read and applied all the "best practices" on the PDF digital signature, so I add the second signature in incremental mode and I am sure that the second PDF has no change in the first part, this is because if I do a binary comparison of PDF1 PDF2, the first part of the PDF2 equals PDF1. So, if you remove the part of PDF2 (after the first %% EOF), you get PDF1, once again, with the digital signature is valid. So the problem seems to be in something again in the part of PDF2 making Acrobat Reader X think that the first digital signature is not valid.

  If you want to see three PDF files, here are the links:

  The original PDF: https://docs.google.com/viewer?a=v & pid = explore & chrome = true & srcid = 0BzrgexS80Iq_ODQxZTY2MDk tNTQyYi00YTE0LTk0MTctYWMxNDFiOWY4MjA5 & hl = en_US

  PDF1: https://docs.google.com/viewer?a=v & pid = explore & chrome = true & srcid = 0BzrgexS80Iq_ZDQ3MTk1ZmI tNWI4NS00YzdhLTkxNmUtODk1NjVmY2M2NTVh & hl = en_US

  PDF2: https://docs.google.com/viewer?a=v & pid = explore & chrome = true & srcid = 0BzrgexS80Iq_ZGM1YmZhMWE tY2JiYi00YzZkLWE5ZjItNzgwM2RlNzExYWE1 & hl = en_US

  Any help will be very appreciated. Best regards.

  Hello

  I don't know if this helps, but I found something unusual with your PDF2. Just at the beginning of the second incremental update (with the new signature), the first object is added without a carriage return. This the last line of the previous update mark looks like this:

  %% EOF3 0 obj

  Perhaps which leads to an incorrect analysis and then invalidates the signature? Not sure on this subject, but as far as I can read offsets, your ranges of bytes are correct.

• My product key on a new installation was invalid so then I activated by phone... now when I use windows update it does not work correctly

  My product key on a new installation was invalid so then I activated by phone... now when I use windows update it is not working properly because it says that I don't have a genuine copy of windows... But it seems that the updates don't come down... is it ok to work this way?

  To analyze and solve problems for Activation and Validation, we need to see a full copy of the report produced by the MGADiag (download and save to the desktop - http://go.microsoft.com/fwlink/?linkid=52012 ) tool
  Once saved, run the tool.
  Click on the button continue, which will produce the report.
  To copy the report in your response, click the button copy in the tool (ignore the error at this stage), and then paste (using r-click and paste or Ctrl + V) in your response.
   
  Windows security updates will continue to come down the pipe under automatic updates, but you cannot access the General updates until the system to validate.

• AVG found that Windows\xreg.exe has been signed with a digital signature broken by Leader Technologies

  AVG found that Windows\xreg.exe has been signed with a digital signature broken by Leader Technologies. Is - this someinthg, I'd be worried?

  See you soon

  KF

  Hi KieranFitzgibbon,

  1. did you of recent changes on the computer?

  2. are you referring to the xreg.exe or ereg.exe?

  If his ereg.exe, then it is related to the registration of Logitech products.

  Method 1

  I suggest that use you the Microsoft safety scanner to remove the infections of viruses or malware to the computer and check if it helps.

  http://www.Microsoft.com/security/scanner/en-us/default.aspx

   

  You can also use Microsoft Security databases to scan your computer

  http://www.Microsoft.com/security/PC-security/MSE.aspx

  Method 2

  If the previous step fails then I suggest that scan you SFC on the computer that would be a system file corrupt on the computer search and replace.

  The analysis may take some time, so be patient. Windows allows to fix corrupt or missing files it finds. If the information of the installation CD is required to fix the problem, you may be asked to insert your Windows XP installation CD.
