With FlexNet Manager Suite 2019 R2, after a 14.0.x or later version of the FlexNet Beacon or inventory agent is installed, attempting to then downgrade to an earlier version (13.8.x or earlier) will result in the application unexpectedly quitting, related to FlexNet Beacon or inventory agent processes after the downgrade completes.
To work around this behavior, remove the following file from the machine:
- 32-bit machines: C:\Windows\System32\mgscmn.dll
- 64-bit machines: C:\Windows\SysWOW64\mgscmn.dll
After removing this file, repair the FlexNet Beacon or inventory agent installer though Add or Remove Programs, or by launching the MSI installation again and selecting Repair.
