Installing .NET Framework 1.1 SP1 slip-stream on 1.0 fails

[srowe]

We are seeing incorrect behavior from the .NET Framework 1.1 SP1 installer (when generated from InstallAware) when the target machine has .NET Framework 1.0 installed.

What we see is an endless loop where the installation appears to work, asks the user to reboot and upon reboot, the whole process starts over. The .NET Framework 1.1 is not installed and neither is the .NET Framework 1.1 SP1.

If we attempt to apply Microsoft's .NET Framework 1.1 SP1 installer, it complains "The program to be upgraded does not exist on this computer", or something to that effect. If we run the std .NET Framework 1.1 installer on the machine with .NET 1.0, that works, and then their SP1 install works.

The only way we have gotten this to work is to have the user uninstall .NET Framework 1.0 and then run our installer. That works.

Is there another, more friendly workaround? Any other suggestions?

Your help would be appreciated.

Thanks,

This is most interesting. Can you confirm that you are using version 050927 (just open the About box in the main IDE) of InstallAware?

I will escalate this and get back to you.

Yes we are using version 050927. This version did fix a similar issue when the .NET Framework 1.1 SP1 install kept requiring a reboot and never accomplishing the install when the target machine had no .NET Framework installed. Now we see a similar problem but only when the target machine has .NET Framework 1.0. The other issue has been resolved with this version, but not this new issue.

OK, I will escalate this...you'll hear from us soon.
