Uninstall hang in Windows 2000

[Steve Hanrahan]

If the control panel Add/Remove Programs is run in W2000 to remove our
program, it uninstalls just fine but never returns control to the
control panel -- you have to end task on it. The task manager shows that
uninst.exe is no longer running, so it looks like the uninstall has run
to completion (it's not hung). We do use a custom uninstall dll.

Our uninstallation works fine for every OS except for W2000.

Steve,

If you remove the custom uninstall dll, does this happen?

Jacob,
I realize this question is several months old but I am experiencing
a similar (if not identical) problem with 5.53 on Windows 2000.
I'm running Uninstallshield with a custom DLL. The custom DLL is used
for the uninstallation of a Palm Conduit from the Palm Desktop Software.
One of the functions that the Custom DLL has to do is to stop the
Palm HotSync Manager, remove my conduit, and restart the Palm
HotSync Manager. The HotSync Manager is restarted by doing a
CreateProcess() as the last step of the Custom DLL. This is what
is causing the problem. CreateProcess() creates the process successfully
and returns immediately. My UninstInitialize() function then returns
immediately. After Uninstallshield exits, however, the Windows 2000
Add/Remove Programs applet is frozen (can't get focus, can't kill, etc.)
*until* I tell the HotSync Manager to exit (by clicking on its
icon and selecting "Exit"). This is very bizarre because if I avoid the
CreateProcess() call, everything is fine. I've also tried _spawnl() as
opposed to CreateProcess() and they both do the same thing.

Any help/advice greatly appreciated.
