Apologies for the delay in reply.. we tried it with the admin login too, but error continues. There is a local printer installed and it is configured properly.

Thank you Edward for you reply!

Yes, there is a default printer installed and configured.

We have a software product where we use Stimulsoft reports. The software has been installed at various places (at least 100 computers). But only on 1 client's computer facing an issue of null reference exception. PFA screenshot of the error.

Any help is appreciated.
