I have Installshield 2018R2 Premier edition. I have a custom prerequisite to install DacFramework.msi. This prereq needs to be installed only if a specific registry key does not exist.
I have tried both these scenarios:
1. When the registry key exists
2. When the registry key does not exist
In both these cases, the prereq installation is being kicked off and I get an error message about installation failure.
In the second case, the installation of the prereq finishes (registry key entry appears, the relevant files are installed to C:\Program Files, Windows Event Viewer shows the installation completion step) but I still get the same error message.
There seem to be two issues: 1. The condition is not being evaluated correctly 2. Errors even when the prereq msi installation finishes
Attached are screenshots of what I have. Can someone point me in the right direction as to what is wrong?
