Quick Time Error #2738 on Windows 7

I receive the error #2738 when I try to either uninstall or install. I googled this and saw that you should register vbscript.dll with regsvr32 - which I did. It says it successfully registered vbscript.dll I try to install it afterwards

Crikey ... haven't seen one of those for a while. But you found precisely the right thing to try first, so you've been doing well.

Doublechecking something ... when you were reregistering vbscript.dll, were you in \SysWOW64\ or \Win32\ ? For the QuickTime install, I'm pretty sure you'll need to register the 32-bit version of the dll (which is kept in SysWOW64) rather than the 64-bit dll (which is kept in Win32).

Hmmm. So the 32-bit vbscript reregisters but we're still getting the #2738.

Let's try to "triangulate" on the issue ... try to download and install the Windows Installer CleanUp utility from Microsoft (we aren't going to be using it for anything ... but a vbscript problem often prevents it from installing or running, so it might give us some additional information on the nature of the VBScript problem):

[Description of the Windows Installer CleanUp Utility|http://support.microsoft.com/kb/290301]

If you get an error message on the CleanUp install, let us know what it says.

If CleanUp does install, try launching it (Start > All Programs > Windows Install Clean Up) ... do you get an error message then? If so, what does that one say?

There is an article on the Microsoft support site that describes how to get the script host processors registered:

For Windows Vista, and Windows 7 you probably need to disable the UAC (or it may just "go through the motions" without actually getting the processors registered.

I hope this helps!

That's a good idea ... if one of the services/dlls that vbscript depends on is unregistered, a registration of vbscript might succeed, but vbscript still might not work. Nicely done finding documentation on the dependencies.

🙂 Excellent news. (Well done wcbncal!)
