Thank you for your help! We eventually figured it out, here is a snippet of our working source <Binary Id="ExecuteCommand" SourceFile="path\to\exe\ExecuteCommand.exe" /> <CustomAction Id="checkDependencies" BinaryKey="ExecuteCommand" Impersonate="yes" Execute="deferred" ExeCommand="perl 'checkDependencies.pl'" Return="check" /> We had to write our own exe to do it however, but that was not really a problem.
Now we are trying to figure out how we can get the perl scripts into the msi, unpacked and on the new system, and run them before install. Is there a way to include the .pl files and our ExecuteCommand.exe in the msi like you would normal components and write them before the other files, or to include them a separate way and have them still be written to disk before the actual install occurs.
