Users using SOLIDWORKS 2020 SP4 Finding Error "The operating system is not presently configured to run this application"

Esther Park

Many users are finding they are running into the following error when closing SOLIDWORKS 2020 SP4 or turning add-ins off or on. 


The issue is currently under investigation by the SOLIDWORKS development team and reported in the software performance report (SPR) 1193884. The issue appears to be caused by a conflict between the latest update of MS Office 365 released on September 1, 2020, and the SOLIDWORKS CAM add-in. 


SOLIDWORKS Development has collaborated with Microsoft Development and Microsoft has resolved this with Office 365 (Office 2019) versions 13231.20262 and 13231.20250 released on September 28, 2020.

If you are still experiencing the error ‘The operating system is not presently configured to run this application,’ please Select the Start button, then select Settings > Update & security > Windows Update to update your Office 365 (Office 2019).

Alternate Solution

To resolve the issue, install the Microsoft Access Database Engine 2010 for 64-bit. Download and install the following:

AccessDatabaseEngine_x64.exe from 


Or, rollback the Office365 installation to a previous version and block automatic updates to Office365 using the instructions below.

    Apparently this happens with 2019 users too, just solved a ticket with a user with the same problem on 2019. Tien also confirmed it happens and works with 2018 as well.

    For users not using SOLIDWORKS CAM. If you open the registry and then Computer\HKEY_CURRENT_USER\Software\SolidWorks\AddInsStartup and "carefully" switch all the add-ins final number from (1) to (0) it will stop the pop up. You can then turn on add-ins as needed.
