Internal Error 2738 while installing QuickCam software in Vista

[simage=105,320,y,left]Recently, while trying to set up some Logitech QuickCam Messengers in one of our public computer labs, I ran into an Internal Error 2738 displayed by InstallShield during the installation process. A quick Google search turned up some information that indicated the error is caused by VBScript not being enabled on the computer. This may be because it was turned of for security (in Windows XP), or because it comes disabled for security by default in Windows Vista. To enable it, simply launch a command prompt (in Vista, you will need an administrative cmd prompt, which you can get by typing ‘cmd’ into the Start menu box and then right-clicking on the cmd icon and choosing “Run as administrator”). Type the following into the prompt:

regsvr32 /u vbscript.dll

That should allow you to re-run the installer successfully. You might want to disable VBScript again afterwards (no idea if it is necessary to run the app) for security. To do that, type the following:

regsvr32 vbscript.dll
