Problem after installing Oracle.

• Boot problems after installing Vista SP2 (KB948465)

  I installed SP2 via update.  During the update process there was a power failure.  After that (I don't remember if it's immediately after, or if a few days elapsed) I had problems with the startup.  Initially, seemed the Startup Repair to fix the problem, but not permanently, and the Startup Repair had to be used repeatedly just to start.

  After a few times of what is happening, Startup Repair did not turn, and the PC wouldn't start.  After about 5 attempts using the decision-making power, sometimes choose the Startup Repair, sometimes choose to load windows normally, he did start.
  I immediately did a system restore to return my PC before SP2 was installed.

  After the restoration of versions prior to SP2, Windows Update showed that the SP2 update failed.  It was on 9 November.  As I need my computer, I didn't reinstall SP2 until I had finished this work.

  As I thought that the problem is probably caused by the power outage, on 10 September, I reinstalled SP2.  Windows Update show no SP2 as an available update, then I downloaded and installed the standalone update.

  Between the 10th and today, 14, Windows Update has installed more than updated.

  Today, I was unable to start for the first time since the reinstall SP2 and Startup Repair has allowed me to open a session.
  I tried to uninstall SP2 via update.  The first part of it seemed to work, but when it came to reboot, the PC stopped at the end power to the bottom of the procedure.  I used the power switch to turn the PC back on.  After startup, the PC told me that deletion failed.

  Then I tried the system restore.  Unfortunately, the first available restore point was post - SP2 installation.  I restored it for the point that is as close as I could.  I tried to uninstall SP2 again through Windows Update.  This time, I receive a generic error message immediately (less than a second) - it does not attempt to go through the configuration - restart the procedure.

  I haven't restarted my PC since then.  Most updates have been downloaded automatically, and the PC tells me that a restart is required.  I'm a little worried that I will end up with a completely insensitive PC.

  I use an Acer Aspire X 3200 with Vista home premium pre-installed.  I don't have a Vista disc.

• Problem after installing Windows Service Pack 3 on Windows XP Home edition error Media pc: files which are required for Windows to run properly have been replaced by unknown...

  Original title: problem after installing Windows Service Pack 3 on Windows XP Home Media edition pc

  My pc runs Windows XP Home Media edition.  I installed Windows Service Pack 3 successfully, or so I thought. Whenever I turn on my pc a box opens indicating "files which are required for Windows to run properly have been replaced by unrecognized versions."  To maintain the stability of the system.  Windows must restore the original versions of these files.  Install your Windows XP Professional CD2.  I don't have any Windows XP Professional CD that I use the Home Media Edition. If I press Cancel repeatedly, the window disappears to return with the same information, but ask me to install Windows XP Professional CD3.  How can I stop this happening?

  Hello

  Step 1: I suggest you perform the SFC scan on the computer and check.

  SFC tool scans system files and replaces incorrect versions of system files by using the correct versions.

  To run the System File Checker tool, follow these steps:

  1. Click Start and type cmd in the box start the search.
  2. right click on cmd in the list programs and then click Run as administrator.
  If you are prompted for an administrator password or a confirmation, type your password or click on continue
  3. at the command prompt, type the following line and press ENTER:

• Problems after installing KB978338 on Windows Vista SP2

  I met a problem after installing KB978338. The update installs without error or problem, but the system is extremely inadmissible after the reboot. The "\Windows\system32\config\systemprofile\desktop is not accessible" error, and the system is practically unusable. Normally opens the Task Manager and system seems inactive, but you try to start a new application from the Task Manager gave an error "hose is not valid.

  System is Vista Home Premium SP2 installed without any obvious problems before the update. Start the system restore and go back to immediately before the update of the results in the system back to normal functionality and responsiveness.

  I've never seen or either of these mistakes before and my research has not yet been able to find something similar, so I am at a loss to start this kind of problem with an update of troubleshooting.

  Please tell us how can I still troubleshoot or solve this problem.

  Thanks in advance.

  Hi Patrick,

  To be honest, your ad is very difficult to understand and I don t know what you mean exactly.

  According to your assignment, it seems that you need a driver and you can get all the drivers here:

  In regards to the FN keys you have Toshiba Value added Package, and Flash Cards Support utility. Everything can be downloaded from the official page of Toshiba.

• HP Officejet 7612: analysis of problems after installing Windows 10

  After installing Windows (prior to Windows Vista) 10, scan documents with my HP Officejet 7612 became a hell of a job.

  Printing is no problem.

  With Webscan, I can only scan and save 1 page at a time, I can not scan several pages of the document 1 more.

  I downloaded "Extended Scan" but when I try to use this app, it says "year error occurred while scanning" without more information.

  With "HP Scan and capture" I can't scan the size of A3 paper full of documents and there seems to be no possibility to change the size of a3 paper. Maximum size is 'legal letter '.

  Same problem with "Windows Fax and scan."

  Are there other ways to recover the possibilities of full scan from my HP Officejet 7612?

  Hello

  WinDVD is the least of your problems: WinXP SP2 should be installed no later than October 10 2006!

  If the computer running Windows XP Gold or SP1 until earlier, may not be a critical functional application of antiviruse protection installed and 3 + years of security updates have not been installed.

  Personal data backup (which none should be considered 100% reliable at this point) then format the HARD disk and do a clean install of Windows.  Please note that a repair installation (upgrade AKA on-site) won't fix this!

  HOW to do a clean install of Windows XP: see method 1 and http://michaelstevenstech.com/cleanxpinstall.html#steps in http://support.microsoft.com/kb/978307

  Once installed the clean, you will have the equivalent of a "new computer" in order to take care of everything on the next page before connecting the machine to the internet or one local network (i.e. other computers) otherwise and before using a flash drive or the SD card that is not brand new, or has not been freshly formatted:

  Follow the steps below to completely remove the HP software. Let me know if you still have problems with the laptop after uninstalling the software?

  1. type % temp % in run

  2. look for a folder called 7z? Example: 7zS6D6F, and then open it.

  3. open the contents of the file Util

• Monitor problems after installing SP1

  After installing SP1, on reboot, the screen works nto correctly.... I see the cursor and screensaver.  .. everything else is black

  WTH?

  Follow these steps to try to solve your problems of boot.

   

   

  Restore point:

  Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

  Try a restore of the system once, to choose a Restore Point prior to your problem...

  Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   

  If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

  Link above shows what the process looks like and a manual, it load the repair options.

  NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

  Read all the info on the website on how to create and use:

  http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

  ISO Burner:http://www.snapfiles.com/get/active-isoburner.html

  It's a very good Vista startup repair disk.

  You can do a system restart tool, system, etc it restore.

  It is NOT a disc of resettlement.

  And the 32-bit is what normally comes on a computer, unless 64-bit.

• Keyboard problems after install "Microsoft Keyboard Layout Creator"

  I bought a new keyboard, a Skyline 895 defender and she did not have some important buttons (such as <> |), so I installed MSKLC 1.4.
  But it turns out it was a big mistake. Now I have problems with key combinations such as ctrl + c and ctrl + v.

  The questions are:

  Sometimes there entry offset, sometimes the information is not copied to the Clipboard, and sometimes after pasting, I get a random amount of info pasted.

  Basically, MSKLC makes my keyboard very unstable and I can't work with my workflow. I've been frustrated because of the randomnes which seems to happen on my PC after installing MSKLC 1.4.

  I tried on another pc without MSKLC keyboard and it works perfectly, no lag, no randomness in Clipboard action.

  It seems that MSKLC has a bug with combinations of keys. Is there a solution for this? Uninstallation of MSKLC will fix this problem and what are the good alternatives to MSKLC? Or do I have to reinstall windows because of this?

  Thank you!

• Problem to install Oracle 11 g - impossible to establish a remote connection

  In short:

  I just installed Oracle 11 g and created a data base and the headset, but I'm unable to connect remotely with a customer database.

  My environment:

  Oracle 11g is installed on a VirtualBox (4.3.18) Red Hat Linux 6.5 VM.  The host operating system is Mac OS X Yosemite.  Linux VM is assigned a static ip address and the host and vm have host entries to resolve this name server:

  192.168.58.152 rhel65opdev-vm

  I am able to ping rhel65opdev-vm from these two places.

  Host: 64 bytes from 192.168.58.152: icmp_seq = 0 ttl = 64 time = 0,287 ms

  VM: 64 bytes of rhel65opdev-vm (192.168.58.152): icmp_seq = 1 ttl = 64 time = 0.027 ms

  I am also able to ssh into the Linux vm without problem.  If I try to telnet to the virtual machine on the port of configured database:
