Problem install .msi file

[Guest]

I have just reinstalled my os and am in the process of putting everything
back in. I have already updated everything using windows update thing, but I
have now run into a problem.

All of a sudden I cannot install any .msi file. I always get an error saying
something along the lines of installation terminated prematurely.

This is a new problem because before having to re-install I could install
..msi files perfectly fine.

Anyone got any ideas on what could be the problem?

Nevermind I managed to install the file using the command prompt (elevated).

Funny thing was it would only install when using the /qb command, but at
least I got it installed.

If anyone else is having this problem, then I'll tell you what I did.

1. ran Command Prompt as administrator
2. changed the directory it was looking at to where the msi file was. eg:
"cd /Users/blah/Desktop"
3. ran msiexec. eg: "msiexec i\ someprogram.msi \qb"
4. wait.

That was it.

I'm guessing the reason I couldn't install was because of the UAC, but I
don't quite understand why this only happened with msi files. Does anyone
know why?
