Hello Daphne
The issues we have covered have been the most common occurences of this error, however there has been the 'odd' one reported that was due (in a nutshell) to trying to run a very old product on a very new environment (i.e. untested).
Have you recently upgraded your Windows version, or bought a new PC that comes with a newer version of Windows and installed QIWIN on it?
If not, has anything else changed since you first installed QIWIN that may have caused it to stop running as expected?
If QIWIN was installed on a network Server, and you got a new station - did you run the workstation setup? If you did run the wksetup - did you (the User you log into the network as) have full Admin rights to install software when doing so?
The printing of reports relies on a successful program install (if it is installed 'standalone') and if the program is installed on a Server, then successful completion of the worksation setup.
For more troubleshooting, it would be very helpful to have a bit of history about your setup, if the above information is not helpful.
Regards,
