Hi Ash,
The easiest (and correct?) way to determine whether a certain application is installed
is to query the registry.
E.g. "if professional installed" would be something like
If RegistryKeyExist("HKEY_LOCAL_MACHINE\Software\MapInfo\MapInfo\Professional\")
Then
A similar approach applies for the runtime, although I don't know the exact key since
I've never had it installed.
You just need to look up the correct registry finction in VB.
Best regards/Med venlig hilsen
