    Hello

    • What application you use to display pictures?

    Try the SFC scan on the computer.

    SFC/scannow is a very useful command that you can use in any version of Windows. When the SFC (System File Checker) command is used with the/scannow switch, the tool analyzes all the important files of Windows on your computer and replace if necessary.

    Missing and the corruption of the operating system (like many DLLs) files are probably the main cause of the major problems of Windows. In view of this, plus the fact that the SFC/scannow is completely automatic and very easy to use, the tool should be usually one of your top not troubleshooting.

    Step 1:

    You can try to start in safe mode and check if the problem persists. Only basic files and drivers needed to run Windows are started. If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic as possible cause device drivers. To start in safe mode follow the link.

  • Runtime error! Program C:\Windows\System 32\Spoolsv.exe this application has requested the execution in an unusual way

    Above message at the beginning turns upward. Have used the difficulty, which explains that he has set the spooler, but it still does not work, and no printer can be installed.

    Hi drhorn,

    To help resolve the error and other messages, you can start Windows Vista by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    Step 1: Perform a clean boot

    Note If the computer is connected to a network, network policy settings may prevent you from following these steps. We recommend strongly that you do not use System Configuration utility to change startup options on the computer, unless a support engineer Microsoft directs you to do so. This can make the computer unusable.

    ·         Log the computer by using an account with administrator rights.

    ·         Click on start toreduce this includes this image, type msconfig.exe in the Start Search box and press ENTER to start the System Configuration utility. Collapse this includes this image

    ·         If you are prompted for an administrator password or for confirmation, type your password, or click continue.

    ·         On the general tab, click Selective startup, and then clear the Load Startup items check box. (The box use the Boot file is not available.)

    ·         On the Services tab, select the hide all Microsoft services check box, and then click disable all.

    Note Following this step lets services Microsoft continue to run. These services include networking, Plug-and-Play, record of events, error reporting, and other services. If you disable these services, you can permanently delete all restore points. Do not do this if you want to use to restore the system with the existing restore points.

    ·         Click OK, and then click restart.

  • When booting I get the Visual C++ runtime library error message. This application has requested the execution in an unusual way. Any ideas how to fix?

    When booting I get the Visual C++ runtime library error message

    Hi ToddLynch,

    (1) since when are you facing this problem?

    (2) remember to make changes?

    It is sufficient to indicate the complete error message you receive.

    Put the computer to boot and then check if the problem persists

    Follow step 1 in the link below,

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

    Continue with the remaining steps to pin-point on the third party service.

    After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

    Important: n ' forget not to put the computer to a normal startup follow step 7 in the link.

    AH HA!

    The culprit is a virtual CD drive.  I have an installed application and allows me to mount a disk image file (.) (ISO) as a virtual drive.  When I have a virtual disk mounted, I get error VC ++, but when I eject the virtual disk, so there is no more virtual drives, DVD Maker is happy.

    Hi Gunnar

    First of all just save the contents of the disk on your computer. Then...

    The local cache paths are stored in the registry keys.  You can change the registry in the following steps:

    1. Select start > run and enter regedit
    2. to create a backup copy of the registry, select file > export from the Registry Editor window
    3. make sure that the export range is set to all and back up the registry
    4. navigate to HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments\Common\Installer\ProductCache, find the right key and change the path as necessary
