Crystal Reports XI crashes using IBM UniData ODBC Drivers


I've been using Crystal Reports XI on a PC running Windows 7 for over a year with no issues. My usual work requires an ODBC connection to a UniData server. That has never been an issue until earlier this week. From one day to the next, I started getting the following error every time I tried to do anything with a connection to UniData:

Problem signature:

Problem Event Name: APPCRASH

Application Name: crw32.exe

Application Version:

Application Timestamp: 4b16581e

Fault Module Name: udtodbc.dll

Fault Module Version:

Fault Module Timestamp: 4726415d

Exception Code: c0000005

Exception Offset: 00012f5c

OS Version: 6.1.7601.

Locale ID: 1033

Additional Information 1: 1fc1

Additional Information 2: 1fc163a1c57ae45571bce37d539b233f

Additional Information 3: cc5f

The error immediately points to udtodbc.dll, the UniData ODBC Drivers. I've tried uninstalling/reinstalling them several times with no luck with Crystal Reports. The thing is, I can make an ODBC connection outside of Crystal Reports. I am able to do so with Excel and with Visual Basic. It has to be Crystal Reports. I've searched and came across and They mentioning upgrading Crystal Reports XI to the latest Service Pack. Prior to the issue, I wasn't even on R2 and it worked fine with Windows 7. I am now on R2 SP6 (version but I am still having issues. The threads also mention disabling DEP for crw32.exe which I have done, but didn't help.

Everything works fine on a different workstation running R1. Anybody have any insight?
