Question

Hi everybody,

I got a problem with application. I have deployed my application and I got .MSi. I have installed it in Xp and it is working fine. But when I install it in windows7, it is showing some errors like:
Unhanded Exception has occurred in your application if you click Continue the application will ignore this error and attempt to continue .if you click quit the application will close immediately

Syntax error(Missing Operator) in query expression "8522"

How can I resolve it? What could be the issue?

Now I am Uploading my .msi File also which will working on XP but not in Windows7
