    Ran in to this tonight trying to un-install a couple RIM OSs:

    Error 2738. Could not access VBScript run time for custom action.

    Couldn't uninstall, install, or repair, no matter what I did, short of reloading Windows.

    Most common fix is to register the vbscript.dll, but this didn't solve it either, even tried to unregister it with the /u switch, same error.

    Here's the fix:

    1- First try to register the vbscript.dll
    A- Click Start "globe"
    B- Type in Search programs and files box> cmd
    cmd.exe should show in list, right click on it and select Run as administrator
    C- Make sure your in system32 directory, if your unsure type:
    for 32bit OS => cd %windir%\system32
    for 64bit OS => cd %windir%\syswow64
    D- Now register the dll with this:
    regsvr32 vbscript.dll
    You should receive a massage saying it was successful.

    Now try to install or uninstall again.
    If you still get error then it's time for a quick regedit:

    1- Click Start "globe"
    A- Type in Search programs and files box> regedit
    regedit.exe should show in list, right click on it and select Run as administrator
    2- Find this key and delete it:
    HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{ B54F3741-5B07-11CF-A4B0-00AA004A55E8}
    Now done with regedit.
    3- Register the vbscript.dll as described above.

    Now you should be able to install or uninstall.

    NOTE: This will also work with VZAccess Manager for RIM, if your getting the same error message.

    Hope this helps anyone having this problem.

    Just be very careful when playing around in the registry. You can screw things up royally.

    +1 ...play it safe. Export your registry file prior to making any changes to your registry.

    Thanks MrZoSo for a helpful thread! As usual Crackberry trumps Microsoft's own support forums.

    Technical note, that for Windows 7 64 bit the registry key I had to remove was HKEY_CLASSES_ROOT\Wow6432Node\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}, after which I registered via "C:\Windows\system32>regsvr32.exe vbscript.dll"

    +1 :-)

    Same here. On Vista 32-bit. Registered the dll, was successful (according to message anyway) but this registry key does not exist. I cannot uninstall either 6.0 or 7.0 from my system. Any other solutions?

    P.S. I use Norton Internet Security, and also Windows Defender.

    **Update also ran the McAfee removal tool (I had used McAfee a few years ago before switching to Norton). It did 'remove' some 'things' but still no go. None of these suggestions have worked, and I have also looked on BB forums, MSFT forums, etc. I tried uninstalling DM as well and got same error.

    Are there any other suggestions for this? I'm on Vista SP2, cannot delete any BB OS that have been installed, and I don't have the registry key indicated above. It's driving me insane!
