MSI install = explorer freezes

[Kwaice]

Hello everyone,

I've had this problem for quite awhile now and i can't find the solution.

Basically, everytime i try to install a program that uses .msi files, windows explorer stops responding then starts to periodically freeze and i end up having to hard reboot my computer.

This is extremely annoying as i can't install important programs like java and such.

I am using windows 7 64 bits.

I have no idea how to fix it, i don't know how to reinstall windows installer.

Thanks for any help.
