Q: ERROR CODE 643 AFTER TRYING TO INSTALL VISTA UPDATE. This thread is locked from future replies

I have to install several times, get error code 643



When you try to install an update for the .NET Framework 1.0, 1.1, 2.0, 3.0, or 3.5, you may receive Windows Update error code "0x643" or Windows Installer error code "1603"

If the above does not resolve your issue:

This is the Vista Install, Upgrade and Activate Forum.

You will get the best help for any Update/Service Pack problem in the Windows Update Forum; link below:

When you repost there, kindly include any Error Codes, and exactly what happens when you attempt to Update.

That way you will receive the best help there.
