Corrupt Permission Settings in Windows Vista

I'm using Windows Vista 32, and I am having the problem of not able t
install software that uses Windows Installer. I get the error messag
saying Windows Installer could not be accessed. I've tried all th
solutions on the net including:
1) Downloading registry fixes and running them
2) going into msconfig (Windows Installer is "stopped" and there i
nothing I can do to enable / disable / start it)
3) Going into services.msc (I've changed Windows Installer status t
manual and tried to "start" but i get error message "access is denied")
4) Trying to find the WOW64 registry key under the Windows Registry an
change it to 0 (but beecause I'm using Windows Vista 32 i don't thin
this is relevant for me)
5) Deleting the ENUM subfolder under the msiservice folder in th
registry.
6) Running scannow under Command prompt, with Windows operating Syste
cd inside
7) Even tried "installing Windows VIsta" using the operating system CD
but I get an error message saying cannot create the require
installation folder!

None of the above worked for me! I still cannot install anything tha
requires windows installer.

Please help..

If the following is useful:
A while back I tried playing with the permissions of folders (i.e
right click on C drive, properties > security tab > users) and
terminated the action while it was trying to apply changes in giving
removing permission to various users and got the information that som
permission settings may be corrupted. As of now I can't set permissio
in C:, in system32 etc. Even though I am the administrator and there i
no other users in this computer, and I have already disabled UAC. Coul
this be the cause of the problem? If so how do I resolve it

Thanks in advance
