Error while installing .net framework 3.5

Question

The .NET Framework 3.5 installation fails for me. Right after the "Downloading components" stage, it sits for a few seconds on "Setup has finished downloading components, you can now disconnect from the Internet" and then it starts to roll back. I'm using XP SP2. A glance in the log files shows that it seems related to MSI error code 1603

Thanks in Advance

Answer 3

You should rename c:\windows\system32\spupdsvc.exe to something else and retry the .NET Framework 3.5 installation. If you using a batch file you can use:
"REN c:\windows\system32\spupdsvc.exe spupdsvc2.exe"
