OK, I've built installer (call it main installer) that has 4 prerequisites: .NET Framework 4.0; .NET Framework 4.5; Installer Package 1 (IP-1); and Installer Package 2 (IP-2).
When I run main installer, the .NET Framework packages are detected as installed, and skipped. The two Installer Packages are not installed, prerequisites check box shows them checked, not found.
OK, then I click next, to run the prerequisites, and that seems to be the end of running the main installer. Neither IP-1 nor IP-2 run, no other installer dialogs display. Even though I have a verbose log option selected on main installer, no log file is generated.
When run on their own, outside of main installer, IP-1 and IP-2 both run with no problem. IP-1 and IP-2 are both of type Single .exe setup (resources inside), both built with AI.
Main installer has worked previously, but now the wheels fell off. Any ideas on how to tell what went wrong?
Thank you.
