I've been able to add code to detect if a copy of the application is running during uninstall, but how do I detect if a copy is running during installation? I thought I'd be able to use the same code, but it gets ignored.

Where did you add the code? Like what function?
If you put in like OnBegin it will get picked up for both install & uninstall.

In the SetupInstall() function.
I'll try adding a OnBegin(), but to be perfectly honest, I am learning Install Shield on the fly and borrowing heavily on snippets I'm finding on the net.

Okay, I'm not familiar with that function, but OnBegin is run everytime, regardless of the scenario, so that will certainly work for you.

Don't worry, I'm not either :)
I believe the person before me didn't know it that well either and made things up as he went along. I made the OnBegin and put my code snippet there, but it still does not seem to work correctly.
Do you have any working code that does this? or a point in the right direction?

I have a question. If the product is installed, why would installation run again? Are you looking for a different product?

so what you want is the following:
1. grep the process list if aourapplication.exe is runnuing -> see sample section of this site.
2. search for an older version of yourapplication.exe installed -> search former install locations and use VerGetFileInfo
ok..looks like you want to apply a patch somehow. For those purposes we use RTPatch and embed this into an installer for getting the needed information to apply the patch.

Becky,
I'm trying to protect the end-user from themselves, because someone out there might actually do it. The problem came up during regression testing and now that it's reared its ugly head, I need to fix it. So, no I'm not looking for a different product.

MKaiser,
I'll look for the sample section, thanks for the direction. I'll let you know how it goes.
