Hi everyone, hope somebody can help us with this issue. I haven't been able to find any other posts with this problem. We are only getting in on 2 different computers, and we cannot find any pattern at all. (Both systems having the error have XP Home SP2 and IE7)

Here is the scenario:

We are using ClickOnce as our deployment process. Our application requires the installation of

1. .NET Framework 2.0
2. Our own Application Framework
3. Our Application

#’s 1 and 2 are listed as pre-requisite components in the ClickOnce deployment.

Upon running the bootstrap, the two prerequisites (.NET Framework and Our own Application Framework) show up and are successfully installed. However, what then happens is that the third installation (the actual product) does not get installed. The installation window just disappears after #2 is installed, and #3 installation doesn’t launch. Watching Task Manger > Processes, we can see that msiexec.exe is still running, but again, no dialogue box, progress box, no error message, nothing. And again, the install works fine on about 40 systems we tested (all kinds of hardware and OS configs) but not on just these 2 systems that are not related in any way other than the same OS.

We looked for popup blockers, turned off anti-virus, but no clues.

Thanks for any assistance

Michael

We've seen a situation where this can happen... if .NET Frameworks 1.1 is already installed on the machine. For some reason we don't fully understand, the .NET Fx 1.1 gets loaded and locked during the web page / setup.exe installation process... and as a result, when setup.exe tries to launch the ClickOnce app, the .NET Fx 2.0 can't launch. If you close down IE and re-run the setup, it usually works.

Hi David,

Thanks for the speedy reply, but that is now what's happening. Let me restate.

Here is what should happen:

1. The .NET 2.0 Framework installs (or skips if its already installs)

2.Our Application Framework installs

3.Our Application installs

4.END

Here is what does happen (but only on 2 systems):

1. The .NET 2.0 Framework installs (or skips if its already installs)

2.Our Application Framework installs

3.END

The window to show our Application is installing never appears.

Hope this makes more sense.

Thanks,

Michael
