Yes this is possible. I've never needed this, but I have an old book from InstallShield Press (2003) with an example in cpp how to read a table from within a custom action. I'm not sure if it is allowed to post this here (copyright), but if this is in principle what you are looking for, I can try to write a "similiar" example and post it here. Or someone from InstallShield give permission to post here. regards Markus ... View more

In my opinion, the "prerequisites" that "InstallShield" provides are only examples, since it is impossible to provide "prerequisites" for all runtime environments for all versions. For this there is the "Prerequisite Editor" so you can create everything you need yourself and it is really very easy. Here can you download the runtimes from Microsoft to create the prereq's Die "Prerequisites" die "InstallShield" zur Verfügung stellt sind meines Erachtens nur Beispiele, da es unmöglich ist für alle Laufzeitumgebungen für alle Versionen "Prerequisites" zur Verfügung zu stellen. Dafür gibt es den "Prerequisite-Editor" damit kann man sich selbst alles erstellen was man braucht und es geht wirklich sehr einfach. Gruß Markus ... View more

What you show in the screenshot is, that the 64-Bit version of mfc140u.dll is installed. But because IsCmdBld.exe is a 32-Bit program you should check if the 32-Bit version of mfc140u.dll is installed. Check your SysWOW64 folder. regards Markus ... View more

You can also use: regasm MyTest.dll /regfile:C:\Temp\MyTest.reg This creates a reg file with the extracted registry info from the dll. Import this into the appropriate component. Take a look at the reg file, that everything is correct. regards Markus ... View more

I have a similar scenario in a suite project. What I did is I have written a small .NET exe console program, which just return with different error codes. In your case, like a vc++ prereq, just return 1641 or 3010 and set the appropriate "Exit Behavior" and "Reboot Request". To control the execution I use the "eligibility conditions" and "detection conditions" regards Markus ... View more
