Any updates?? 

Half of the modules have disappeared now - including Payroll and Job Cost. I appear to be the only Windows 11 user in the company. Reinstallation didn't work either. 

Is your application Sage 300 ERP or Sage 300 CRE?

If Sage 300 ERP, please contact support (1-800-253-1372) to have a look.

Using Sage 300 CRE

EDITED

FIX:

Close Sage

Go to folder --> C:\ProgramData\Sage\TimberlineOffice\9.5\Shared\Config\Timberline Office Desktop\Tasks

Changed the filename PRProvider.acx_22_2_1.bak (numbers might be different but it should be a .bak file) to PRProvider.acx

Reopen Sage and the Payroll module should appear again ;)

Moving this post to the Sage 300 CRE forum in the Sage Construction and Real Estate support group.

Thanks,
Derek
