i am using Installshield Professional for windows Installer 2.0.

And our application is a small one with no keys being created in registry.

Now,  i  want to abort 'Uninstallation' if the application is running.

Any clues are welcome..

i just read that we should use Maintence() function to create a key in registry and check that before unisntall.
Now my question is: if i create a key in registry then, is it necessary to reboot the machine after completing installation?

Please help.
If anyone has simpler solution, pl let me know.

Just realised that Maintenence(),  DeinstallStart() are NOT supported in Installshield Professional for Windows installer!!!

help awaited!

Can you detect if your app is running using FindWindow?

If you can, you can author a Custom Action that, if it finds the App using the FindWindow function, create a property for it (ex. call MsiSetProperty (hMSI,"AppRunning","1") to create a property called "AppRunning", and set its value to "1".)

Place this customaction in the UI sequence (using a condition "Installed" or better "ProductState=2 OR ProductState=5").

Later in your UI sequence, author a TYPE 19 Custom Action, giving it's Target Field "Must shutdown app before you uninstall...", and call this customaction later in the UI Sequence given the condition "AppRunning=1". This will abort the install / uninstall with the message specified.
