Answer 1

If you have programs that require .NET Framework 1.1 support, then the Service Pack is important.

For help with your issue, you need to provide full install logs as follows:

collect your install logs with this:

http://aka.ms/vscollect

After you run Collect.exe, you'll find vslogs.cab in your %temp% directory. Please upload vslogs.cab to a public site, like SkyDrive, and post the link here.

You should also verify your .NET Framework 1.1 with this tool:

Run the tool with .NET 1.1 selected, then post the first 15 lines AND the LAST 15 lines of the tool log here.

Answer 2

Hi,

This issue may occur if the MSI software update registration has become corrupted, or if the .NET installation on the computer has become corrupted.

Please try Fix MSI software update registration corruption issues or Repair the .NET Framework which you can refer to:
