difficulty sorting out a 1603 error
Hello. I have an installer that works on thousands of machines just fine, but on a handful I am getting error codes from several custom actions "returned actual error code 1603 but will be translated to success due to continue marking", with an ending message of "CustomAction <x> returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)" I'm having a difficult time determining the actual problem from the log (attached). Any help would be very much appreciated. Thank you!
