My Application was developed using c#.NET with java web services to connect to oracle database. It is working fine with my windows XP machine, but when i deployed the same app in another win7 machine by just cpoying the release folder with dll and exe files and launched the app shows the error message "Application has stopped working". I checked for the dll files and exe files nothing is missing in release folder which i gave.
But after deployment its been worked for few days without any interruption. What's the reason which sudenly prompts this message. can anyone help with this issue?

Did you run it as administrator?
Because I used to have the same problem.
When I had run it as administrator all my problems where gone.

Yes, its been run by an administrator, but the problem doesnt occured agian.
