[wix-users] pass credentials to a service and retry if wrong

Fri Aug 7 16:32:48 PDT 2020

many thanks to you all for the help

How do I pass parameters through LaunchElevatedApplication? Is that a
bundle function? Actually I (or google) can't find any info so if there are
docs please point me in the right direction

thanks again
Alan
