I recently upgraded to Advanced Installer Professional 13.2, and my installer now crashes. I've narrowed it down to the condition for my install prerequisite (a Windows update). My install condition is set to Search done by a custom executable, with the exe being C:\Windows\System32\cmd.exe and the arguments /c "wmic qfe get hotfixid | findstr ^"KB971512 KB971644^"". If I change the Install Conditions to Always install prerequisite then the installer does not crash. I was previously using AI 13.1 and did not have this problem.
I've attached a sample project to reproduce this. Please note that the update I am trying to install is for Windows Vista x86 SP2 only, but I've set the Supported Windows Versions to all versions for testing purposes.
