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

Hi,

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

From the Start Menu, Click All programs followed by Accessories
In the Accessories menu, Right Click on the Command Prompt option
From the drop down menu that appears, Click on the 'Run as administrator' option
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.
In the Command Prompt window, type: sfc /scannow and then press Enter
A message will appear stating that 'The system scan will begin'
Be patient because the scan may take some time
If any files require replacing SFC will replace them. You may be asked to insert your Vista DVD for this process to continue
If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations"
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: http://support.microsoft.com/kb/936212

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.

What are the error messages you get? It is hard to answer such a question without any specifics. We will be glad to help.

It would also be better to start your own thread since this is an old question.

Thanks,

Marilyn

BUMP

Old question, but still unanswered.

I have the same issue going on. Trying to install McAfee brings up the error message that javascript needs to be enabled (and it is and up to date as I have just verified). Trying to install an adobe update brings up error 1601 stating that the Windows Installer Service could not be accessed. I have tried the msiexec unregister / regserver thing without any result. Trying to also install AVG (as I can't get a virus scan on here I am worried) but it just times out. Some Windows updates are going through OK, but some are either hanging the computer or failing all together.

Once trying to install anything, the whole system goes haywire and slows right down, making the pc unusable until rebooted.

This PC was also a "clean" install without ever having a previous OS on it. My version is Win 7 64 bit home premium.

Help!!!!!

This PC has same issues. Trying to install McAfee gives the message that Javascript should be installed (and it is, plus is up to date). Trying to install an adobe update advises that the Windows Installer could not be accessed. Trying to install AVG, system hangs. Some windows updates go through, others hang the system or just fail all together.

Clean install of Win7 64 bit home premium ed. No previous OS here.

Can't install a virus scan so PC is a little useless...

HELP!!
