Problem with LaunchAppAndWait

[jackie]

I'm using InstallShield v5.5.3 and getting some weird behavior on Win2000. The installShield uses the LaunchAppAndWait to launch the unzip.exe to unzip the files. In some Win2000 systems, it behave correctly and unzip all the files. However, on other Win2000 systems, it failed to unzip the files. Does that have something to do with the Win2000 system setups?? Any help will be appreciated.

On the other Win 2000 systems that it doesn't work on, can you run the unzip.exe standalone (i.e. through Windows Explorer), If not then there is no problem with LaunchAppAndWait, there is a problem with the dependencies for that executable. You can check it using a program like Dependency Walker (get it at www.dependencywalker.com)

It has no problem running the unzip standalone on the Win2000 system. That's why I'm wondering if there's any Win2000 system setup that may cause the LaunchAppAndWait not function correctly. I can see the screen flashes as if it was executing the unzip. But I guess the LaunchAppAndWait desn't wait till the unzip utility to complete.
