问题
I've made an application in C# . it's a WPF application with SDF DB. I have VS2008 express. I published my application (with SQL-CE dll) and installed it on my computer (I have windows XP) and on another WinXP computer and it worked fine. I sent the same files to 2 people with windows 7. the first one couldn't install the application - she got an error message like "cannot download the application [...] missing required files [...]". the second one (window 7 with 64 bit) installed it but she could see only the main screen (that doesn't require DB) but after she tried to go to another screen - the application crashed and there was an error message that told her that maybe the application wasn't installed correctly (I have a screenshot but it's in hebrew).
What do I have to do to make the application work on windows7?
