Question

I had a msi installer which has custom action install and uninstall runs perfectly on windows xp and 7. That project was on vs 2005. Then I update that to vs 2010. Now it works fine in windows 7 but when I try to install it on windows xp sp3, it is not working. I'm getting "There is a problem with this windows installer package..." error. It seems my custom action install don't get start from the msi. what could have gone wrong?

Error was I'm missing mfc100.dll in Win XP. When I installed Visual C++ redistributable package 2010 for Windows form it works fine.

It's likely a dependency problem. It's hard to say without knowing what language your CA is written in (C++?) but check that you have the right dependencies either linked to your CA or installed on the target machine. Depends is your friend.
