msiec.exe or the windows installer is really messed up on my computer.

I was trying to install MSN Live, and the installer crashed on me. So now, whenever I try and install ANY Windows applications, the windows installer pops up, and says "We have detected that another installation is in process, please close the process to proceed".

The thing is, its NOT opened, it just says that because the Windows Installer previously crashed when I tried to install Live.

So...Does any have sufficient enough knowledge to try and fix my computer problem?
I think what I'd have to do, is re-install Windows Installer, but I don't know how..And I don't know if that will screw up my computer or not.

Thanks in advance!

Yup, I read it, and it was a very detailed explanation.
Thanks alot for it

Okay..So I fixed my Windows Installer problem..(If you read it before..If you didn't, don't pay attention to this)


Basically, I fixed my Windows Installer problem, JUST so I could get MSN working..But it's still not working.

Whenever I start the most recent MSN installer, I always get these damn things..

^ Thats the picture of me first running the installation, everything seems to be working fine.

Then..After about 1 hour (Yea, a FRIGGIN' LONG TIME), this shows up..

Then I get some gay error, that looks like this:

Does anyone know how to fix this? I want to get the NEWER Version of msn, I HATE the old version..

I honestly don't know what it means by "Install Servers Not Responding", because I've tried this many times, with and without my firewalls, anti-virus, and w/e else on.

Thanks in advance!..
