Hi - just finished a clean install of Windows 7 this afternoon ( upgrading from XP ). Running a homebuild system : Gigabyte GA-8PENXP Mobo, 2GB RAM, Core2Duo 6600, Nvidia 8800GTS Graphics. Install went cleanly no errors or hiccups. Problem is I can't install anything. Tried to download an install AVG and Avast AV products, both installers failed. iTunes installer just does nothing. However, I have successfully installed Office XP Pro and Stanza eBook reader. Turned off UAC - no difference. Ideas appreciated. It's driving me nuts



SOLVED! ~ Well for me 


I'd been having this same problem with updating windows / vc_red.msi problems & installing programs 
tried everything literally been goggling for days thought it was a corrupt registry / then maybe some anti-virus programs finally found this forum 

Followed the recommendations & my computer is back working perfectly, can install & update like normal.
Really hope this helps someone :-)

Welcome to Microsoft Answers Forum!

I would suggest you to perform a System File Checker [SFC] scan on the computer

 Steps to perform SFC scan:

 1. Click the Start button

2. From the Start Menu, Click All programs followed by Accessories

3. In the Accessories menu, Right Click on the Command Prompt option

4. From the drop down menu that appears, Click on the 'Run as administrator' option

5. If you have the User Account Control (UAC) enabled, you will be asked for authorization prior to the command prompt opening. You may simply need to press the Continue button if you are the administrator or insert the administrator password etc.

6. In the Command Prompt window, type: sfc /scannow and then press Enter

7. A message will appear stating that 'The system scan will begin'

8. Be patient because the scan may take some time

9. If any files require replacing SFC will replace them. You may be asked to insert your Vista DVD for this process to continue

10. If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations"

11. After the scan has completed, close the command prompt window, restart the computer and check.

Additional information: How to repair the operating system and how to restore the operating system configuration to an earlier point in time in Windows Vista:

 Also try to run program as an administrator.

To do this right click on a program which you are trying to install and click on “Run as an Administrator”.

Also try to run program in compatibility mode and also check whether that program which you are trying to install is compatible with Windows 7 or not.

Check the link which talks about How to run program in compatibility mode.

Also click on the link given below to check for the compatibility.
