Crystal Reports 12 - .Net 4.5 - LogOn Failed

Hi

  I have an app that I am deploying on the end-user's machine. The app also calls a couple of crystal reports reports (non- embedded). The reports are running fine on the dev machine. But when I deployed it and run from the user's machine, 'LogOn Failed - Please try again" error is thrown when the report is loading.

I installed Crystal Runtime (SP7) on the client machine.

I installed the SQL ODBC (native client) on the user's machine.

But the error persists.

The reports are running OK on my (dev) machine.

I would appreciate any help in this regard.

Thanks

Kanthi
