Windows Installer 4.0 Corruption

[Guest]

I can't install anything anymore. I cancelled the install of Visual Studios
2005 when it hung, and ever since then I get the message:

"The Windows Installer Service could not be accessed. This can occur if the
Windows Installer is not correctly installed. Contact your support personnel
for assistance."

whenever I try to install anything msi.

I can't figure out how to reinstall the Windows Installer, because there
doesn't seem to be a standalone re-installation package available, and I
don't really want to reinstall windows. Any ideas? I tried some of the
suggestions for earlier versions of windows installer, like checking security
settings of stuff, and everything seems fine...

Try using system restore to restore the computer to an earlier point before
the issue started happening. Start > All Programs > Accessories > System
Tools > System Restore.

Thank you for your responase, I tried that at your suggestion. Sadly the
system restore failed. It said that the point became corrupted (it was the
only one there was). Then it added a new restore point which was undoing the
partical restore that failed.

So still no working windows installer for me. Any other ideas? Can I somehow
force a reinstall of that component? Can I clear some key somewhere, or issue
some compolex extraction from a random cab file? *cry*
