Error 1719: Windows Installer

[hatred]

Whenever I am trying to download and install some new software, I am always getting some error message that says "Error 1719: Windows Installer could not be accessed". Does anyone know how to fix this issue? Thanks.

This problem can occur if one of the following conditions is true:

1. The Windows Installer files that are on your computer are damaged or are missing.
2. You install or remove a program that uses the Windows Installer Microsoft Software Installation (MSI) package file (.msi). For example, this can occur when you try to install Microsoft Office on your computer.

So to solve this issue, follow the steps given here - http://support.microsoft.com/kb/315346/en-us

Sorry for the bump, but I'm having this issue, been following the directions on the link posted above, except I've hit a snag.

The second step i have to do it "b. Expand HKEY_LOCAL_MACHINE, expand SYSTEM, expand CurrentControlSet, expand Services, and then click MSIServer."

The only problem is that I don't have a folder named CurrentControlSet, I've got one called CurrentControlSet001, CurrentControlSet002 and CurrentControlSet003. Any idea what I should do? Modify just one? Modify all 3?
