Making a Pre-requisite self-contained within my installer
I am using InstallShield 2018.
Recently, Microsoft moved its direct download location for their standalone .NET 4.7.2 installer.
This breaks our current installer. One of our components absolutely requires 4.7.2 or later in order to run. I tried making a copy of the PRQ file and changing the download location, but for some reason this does not always work. We've since decided to make our installer actually contain the .NET installer as a "child installer" but the pre-requisite system doesn't seem to be able to unpack or find the EXE in order to run it.
What's the trick to doing this? We must produce a reliable installer that works with minimal user intervention, so this is becoming a critical issue.
