App exe crashing at startup. Faulting module path c:\windows\syswow64\kernalbase.dll

Question

Whenever I try to launch my app on a machine that isnt mine it crashes at start up. I am at a loss and have done a ton of searching with no resolution. There is no real error I just get the standard windows 7 not responding. All machines are win7Pro 64 with .net4. I am seeing the event viewer logs below.

Event id 1000:

Answer 1

It looks like frmMain.refreshEmpInfo contains a LINQ query that retrieves a record from the database, and the LINQ query calls First() to get the first record. Is it possible that no records are being returned, which would cause First() to throw an InvalidOperationException?

(It might be helpful if you posted the code in frmMain.refreshEmpInfo. You might also want to wrap that code in a try...catch block and display the exception details in a message box.)
