Thanks everyone for the input. This at least gives me a few more tools to look into the problem to try and diagnose what the issue could be.
I just barely found out from the customer that the temporary solution I sent him has worked. Bascially, I created a new installer just for him. I changed the upgrade code and changed the value under the <Media Cabinet="[value]" /> so that Windows would think this is a new product. That has work for him. However, I still want to understand what is wrong with my other installer. I only wanted that to be a temporary solution. Thanks again everyone for the input again. I really appreciate it. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/SOURCEMGMT-Failed-to-resolve-source-MainEngineThread-is-returning-1612-tp7598095p7598116.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
