• Satellite P300-1EU - msahci.sys missing for Vista

  I have a problem with the Satellite P300-1EU, Vista not started because he wanted msahci.sys file.
  I have no restore DVD. You have a solution for this problem?

  Cordially Rb

  Is that what you have just activated AHCI against drives in the BIOS? If to put the setting back to the IDE and the problem is solved.

  If you can start your computer in safe mode, then the AHCI driver should reactivation. There is a solution with a single click here [http://support.microsoft.com/kb/922976].
  If msahci.sys is not on your hard drive, then there are sites that allow download of system files. I think that the file must be in c:\windows\system32

• Windows Installer service is missing from my Vista 32 bit. How to re-install Windows Installer?

  Windows Installer service is missing from my Vista 32 bit SP2. How can I re - install Windows Installer? None of the 27 sets of update and Installer Cleanup solutions worked, a last resort option could work but it will not install without the Windows Installer Service.

  I tried each FixIt option, says the problem is solved, but isn't.
  I tried install Windows Installer 4.5, but it came back as not relevant to my system (because there is no previous installer to update).
  Tried a number of recommended patches, but they are all geared toward fixing the problems of Windows Update not a lack of Windows Installer.
  MicrosoftFixit50202.msi seems to have corrected Windows Update on my laptop but it won't install on Vista pc because there is no Windows Installer.
  I ran the installation disc the option 'fix' with the original, it finished but has not replaced Installer and nothing was fixed.

  How can I put the installer of Windows on my computer?  If there are files on the original drive that can be put into drive C what are they?
  Someone suggested to uninstall Service Pack 2, and then reinstall, but if I have no installer of Windows that may not work. Others said they reformatted to correct same question, but it did not work.

  These previous solutions have not helped:
  Could not locate the installer of Windows on Vista Home Premium 32 bit.
  Difficulty the installer of windows vista sp2
  code641/MSI
  Failed installation error msg error 80070641 Windows update

  After a month of butting heads with the refusal of Microsoft to actually help except to sell us all a new copy of Vista or Win7 at the normal price I solved the problem myself.

  1. I made a list of all my software purchased, including required registration keys, etc. and site URL for those who I don't have a disk for.
  2. Deleted registry back up on my external hard disk, reloading apparently one makes the backed up registry problems breed more.
  3. Inserted my drive from Dell to factory since 2007 and restarted. Press a key to boot from the CD. Chose "reformat hard drive' first, then when prompted hit"Reinstall"(slightly different wording on your computer).
  4. After you have reinstalled the factory disc 32-bit Vista, I spent hours 7 next installation of SP1, SP2 and hundreds of updates. Note that several times Windows Update said some updates to date has failed, but finally everything installed correctly by repeating the sequence of installation/reboot to update. There have been a few files that reported to turn off computer completely, I've shown... clicked with indicator shutdown (stop), let it do its thing until it turned off the computer and then the computer restarted manually later. After a total of 8 hours and 14 minutes as my Vista has been fully loaded, updated the installer is still intact, everything works very well and did not cost a penny.

  It has been 2 days since the reformatting/reinstall. I reinstalled all my additional software without problem. System Mechanic is back in service without any prejudice to my installation Service. Seems that something is involved with .NET Framework 4 triggered a defense mechanism that caused the installer should be deleted, solved the problem of the .NET Framework from Microsoft, but it can be installed by the installer being removed to protect our computers. The question was not just with Dell computers, it is Dell support is just as incompetent that Microsoft support batch so more Dell owners were here to complain.

  --------------------------------------------------------------------------------------------------------------------------------------------
  FYI: my mobile Samsung with Win7, the correction was easier because my installation Service has not been removed:

  1. Uninstalled all the software using .net Framework 4 (only 2)
  2. Uninstalled all .net Framework 4 bodies found on my list of programs (Client Profile and Essentials)
  3. A ran my System Mechanic to remove debris aka too much clutter and correct registry problems
  4. Laptop rebooted then ran Windows Update. All the updates installed with 3 requiring the judgment to install. .NET framework reinstalled with updates.
  5. Reinstalled my 2 pieces of software that use .NET Framework.

  It has been 4 days without any problem at all. So, in my case, it's .NET Framework 4 that created and continued the problem, even if the specific audit FixIt kept saying all .NET Frameworks have been installed correctly.

• Firewall Windows authorization driver is missing - mdsdrv.sys and therefore cannot start the Windows Firewall

  Original title: "Missing mdsdrv.sys driver is missing on my system so I can't launch the firewall. No idea how to restore this driver? "
  I tried the solution of SFC/SCANNOW - nothing appears. The TXT file is empty.

  I tried the solution repair.bat - nothing - not even sure it ends; the black screen disappears without any messages

  I tried the Microsoft Fix - it - nothing outside of a message 'Sorry - you'll have to Fix-it-yourself' telling me the firewall must be enabled manually. YES, I KNOW WHO!

  I'm going crazy that I installed and uninstalled various malware detectors/antivirus programs and still no change. I'm sick to death of it and above which, I can not install my new printer/scanner because he needs the firewall so that it can communicate with the laptop and of course the firewall is in a coma so don't not speaking.

  My husband has a computer on which the Firewall works, can I just copy the folder more or what I need to back up and reinstall Windows 7?

  Hello Kiwipon_CC,

  Do you have any other software installed that contains a firewall?  How long have you had this problem and have you made changes to your front the computer this error?  You have installed new software before it happens?

  Firstly, I would like to launch a full analysis of the software removal antivirus and malware, you have already done.  I would then run a SFC scan to see if it can fix this problem.

• Chinese Applet handwriting missing in IME Pad on 64-bit Windows 7 Professional

  After you have correctly added the language "Chinese (traditional, Taiwan)" and the "Chinese (traditional) - new phonetic" keyboard on my 64-bit Windows 7 desktop system, I couldn't find the 'Writing' Applet in IME pad.  Several new close examination of the pattern and rendering parameters no answer to the mystery.  What is even more puzzling, is that in the list of "Available Applets" in the traditional Chinese IME pad on the Windows 7 system, I found the writing Applets for the Japanese and Korean without ever installing languages/keyboards.

  I have been using the Applet of traditional Chinese writing on 32-bit Windows XP Professional for years and it is a very useful tool.  After that reading messages in this forum and on the Internet, it is amazing to realize that (1) I'm not not the one disagreeably abnormal meanings, (2) that Chinese simplified Windows 7 has the same problem, and (3) that the other versions of Windows 7 have also the same problem.  Was this an oversight?  This will be resolved in a future Windows Update?  I certainly hope that there is light at the end of the tunnel.  Please notify.

  Thank you very much for sharing your experience and your solution with us.  I tried your solution and it works!  Finally, after three years my computers can make Chinese handwriting recognition.

  When I bought a laptop with Vista Ultimate x 64 more recently a desktop computer with Windows 7 Ultimate x 64 and three years ago, I can not get the application of Chinese writing.  Just like so many spectators of this forum I too can't get the icon to make the selection - just Japanese and Korean writing were available.  Now, both computers work properly.

  BTW, I have experienced and learned that I have is useless to have the open c:\windows\syswow64\notepad.exe more.  I can, for example, start Outlook mail and write Chinese characters without Notepad running in background.

  Thank you again for sharing your solution.

• Msahci.sys BOOT ERROR! HELP ASAP!

  Hello, so earlier, I tried to free up space on my C: drive and I thought it would be a good idea to move the 'users' to D out of C. I was doing that through CMD, I had never even try to move it because I tried to restart my computer before, but now when I start my computer it says msahci.sys is missing or damaged and will not start, I don't have my installation disc and I don't know how to fix this help please you both.

  IMHO: USERS is not one of these files you should move after the initial installation, as it is references in so many places / in so many ways.

  However, that said, it is unlikely that he has caused this problem.  After all - different places.  ;-)

  Assuming that the error looks like this:

  Windows boot manager error
  File: /windows/system32/drivers/msahci.sys
  Status: 0xc000000f
   
  Windows failed to load because the file is missing or damaged.

  You must be able to start to external media and go to the appropriate location with a known good copy of the file missing/corrupted and replace it...

  This may solve this problem - but there may be all sorts of other issues, depending on what all you did that caused one you see now.  You can even find yourself at this stage:

• Satellite C55-A-1R8 - lack of 64-bit Windows 7 drivers

  Hi everyone, I need your help guys.
  I just bought my new Satellite C55-A-1R8, computer PSCJEE laptop with windows that I hate windows preinstalled to 8.1 and intel cpu onboard, but because n3520 8 I decided to downgrade to the thought of 64-bit windows 7 I'll find all the drivers, but the problem is that there is no driver win 7 for this model of support and I think that I already tried all the others without success.
  My usb ports does not work and I can't find the drivers, windows cannot do either.

  My missing drivers:

  Enthernet controller
  PCI encryption/decryption controller
  USB universal serial bus controller
  unknown device (properties said on processor Intel (r) Pentium (r) N and J-series / processor Intel (r) Celeron (r) N - and)

  also my bluetooth driver seems to be ok, but I'm not able to install any software of Toshiba bluetooth for win 7.

  If somehow I could sort my usb ports would be perfect.

  Guys you have ideas where good drivers?

  Thanks in advance!

  At first, I must say Hat I just hope that you have created recovery DVD or USB until you started with OS downgrade. Problem is that now after the new operating system installation you will not be able to start the installation of HARD drive recovery image and one day if you want to have the factory settings you can have a big problem.

  In any case, I m wondering really you have installed before Win7, check if this older OS is supported or not. You can try now is to install the Win7 drivers available for other models of laptops.
  Try please install follow rivers:
  Chipset Intel HM70 River (should help with USB ports)
  I put t know for sure if this wll help but try to install please follow drivers LAN and BT:
  Atheros LAN driver LAN
  Driver package Bluetooth Filter filter BT

  Please test and send feedback.
