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?

1. Do you have the proper .NET Framework installed? For example, if you have written an application targeting .NET 4.0 as you have tagged your question, do you have .NET 4.0 installed?
2. Did you debug through your code and check if you're getting an exception?

Solution 1

Do you have all the external software you use loaded on the Windows 7 machine?
Since it is complaining about a query expression, it may be that you need SQL server 2008, or Excel, or some other system loaded. Since we don't know what you are using, it is not possible to be more than vague!
