Cannot lauch interactive window

If I try to run a instrument driver I get the attached error messages. Any ideas how to fix that ?

The problem is caused by the time stamp on the iw.exe file and the iw.cdb file not matching

Thanks;  that was the problem. I fixed that by copying iw.exe and iw.cdb from a working CVI 7.1.1 installation. But I'am still wondering, how I managed to get the different timestamps ( .cdb file dated 26.07.04 and .exe dated 17.02.2005).
