How can I install the windows installer 5.0?

I've been dealing with it for over 6 mths. I feel your pain. This is ****. I've tried everything their tech guys have asked me to do, you would think they would at least give their tech guys a patch or something. They want me to pay them to try and trouble shoot but it might not even work. I'm giving up.

Thanks for the offer but I read the comment under it and there seems to be a lot of issues with it and I am already having enough problems with my computer due to the fact I can't update key software thanks to the lack of the installer that I don't want to take my chances.

To all of you having this problem, SORRY!  I just went through this for the past 2 months, and used their special services, and tried EVERYTHING they suggested!!  All I got out of it was a bill and some bad advice.  Microsoft does not have a clue!  Save your selves some time and aggravation and format and reinstall.  That is ALL that has worked so far.

I REALLY wish MS would get their _ _ _ _ together!  <removed>!

Hi mrclean85,

1. What is the issue with Windows Installer?
2. Do you have any issues installing any program?
3. Do you get any error message related to Windows Installer?

We cannot install Windows Installer 5.0 as it is the default version in Windows 7. If you can provide us more details about the issue, then we can assist you better.

If Windows Installer is malfunctioning, then try to Unregister Windows Installer, and then reregister Windows Installer. To do this, follow these steps:

a. Click Start, type cmd, right click cmd and click run as administrator.

b. On the command prompt, type "msiexec /unreg" and then press ENTER.

c. On the command prompt, type "msiexec /regserver" and then press ENTER.

d. Check the difference.

It didn't work for me.  I can't install Itunes but everything else works
