SDK Return code 2 from Everything_Query(True)

[daspud]

I am using WinDev to connect with the Everything.DLL. It seems to work perfectly on my systems (win 7 and win 8), but not so for one of my customers. The GetLastError returns 2 (no IPC) whether or not Everything is running.

Is there something else besides Everything not running that could cause that return?

How would I go about figuring out what the problem is?

Thanks for any help

Are both apps running as administrator?

EVERYTHING_ERROR_IPC can occur if the Everything window is not found or WM_COPYDATA failed to send the IPC query.
