The Windows Installer Service can not be accessed.

Well I wanted to install Microsoft Office 2007 on my computer last night and I got an error message saying that "The Windows Installer can not be accessed. This may be becuase you are running Windows in Safe Mode." I went to Micorsoft's website, I followed all of the steps. I went into the registry, everything was fine. I did a MSCONFIG on the PC and went to Services and checked on Win Installer and it said it was stopped, so I enabled it again, restarted and the problem is still there. I tried to re-install Windows Installer, but it said that the version is not needed becuase it does exist on my pc. Now I can not install or unistall anything on my pc.

Please help!!!

Did you visit that link?

 

Yes I spent over 2 hours yesterday. I think I must have re-started the computer a hundred times.

Any other suggestions??

 

Have you been able to install things in the past? If so, you might try a system restore point. Other than that, after 2 hours, I think I'd go the hard way and reinstall Windows

Someone else may have a better suggestion.

 

I have been able to install and unistall in the past, but my only problem is that I am unsure of when this problem started.

 

Well, what you "could" do, is experiment. Make a restore point for today, then you know you can get back to where you are now.
