I'm using "Advanced installer" for a few years and it's working fine.
I'm developing a C# service.
Lately the versions that I'm creating don't upgrade well.
When I'm installing each version by itself without upgrade everything works fine.
When I'm upgrading version to another version, the upgrade seems to pass correctly but an exe file is missing which causes my program not to work.
I couldn't find any relevant change in my code and also couldn't find any explanation on "Event Viewer".
I couldn't find any difference on file definition on "Advanced installer" between the missing exe file and another exe file.
Do you have any idea what is the issue or how should i proceed in investigating this issue?
Thanks in advance
Amir
