To troubleshoot this I'd reboot the computer, then run the app as the very 1st thing. Do you still get the error? If you do, what software that might be loading the report(s) loads on startup?
If you do not get the error, what other software that may load the report is used on that computer?
You could use Process Monitor and see which software loads the CR runtime. This will be a very arduous exercise as you want to run ProcMon without any filters. This will result in pretty sizable logs to go through. But searching for crpe32.dll or crystalDecisions,crystalreports.engine may tell you which apps are loading the runtimes.
