Plz Help me with InstallShield 8

There is this *.msi package for a Visual Basic Application that was developed under InstallShield 7.

If the VB App is uninstalled, the /program files/[install dir]/ folder is removed also, along with its contents.

However, after converting the MSI to InstallShield 8, this no longer happens.
Now, when the VB App is uninstalled, the /program files/[install dir] folder still exists, even though everything in the folder was removed.

I've installed up to Service Pack 2 for InstallShield 8.

Does anyone know if there is some setting? Or something I'm doing wrong?

Moved from General Developer forum.

Wow i figured it out. What a wierd cause.
Anyway I should have been using InstallShield Professional Windows Installer Edition instead of InstallShield Developer 8.

That solved the problem for me at least.

I'm still not sure why InstallShield Developer 8 would leave the empty program folder though.
