Windows June 8 2021 Security Update (KB5003637) Disables Adobe Reader PDF Preview Support in SOLIDWORKS PDM

Article by Joe Medeiros, CSWE updated June 16, 2021


Issue: the recent Windows Security Update (KB5003637) released in June 2021, may break the integration of Adobe Reader ActiveX within SOLIDWORKS PDM. This can result in a black window when previewing a PDF, or on some systems, this may cause SOLIDWORKS PDM to crash! There have also been reports that right-clicking a PDF and trying to use “Open With” to open the file in either Adobe or Chrome will crash Windows Explorer.

Solution: This 3DEXPERIENCE Technical Partners Community article provides details on this alert and a potential workaround for SOLIDWORKS PDM Professional. You can use your SOLIDWORKS ID to log in. If you are not able to access the article, please follow the instructions below.
