Hi, i have same situation, but all windows/temp permissions are read/write, in my case, the aspnet application works good and at any moment the load report filed error appears, why is happend this ? for the moment my only solution is replacing all the application files with a backup. But the reports will work 1-7 days, and later the error will show again.
My server has sap crystal reports 32 and 64 bits version 18.104.22.1686
I have recently had this problem pop up out of the blue. The report printed fine in house but at the customers site we got the failed to load message.
After much messing about we found that the customer had uploaded a new image which was displayed on the report. It seemed to be a perfectly good jpg, however Crystal seemed to take exception to it, and crashed. Replacing the image fixed the problem.
