Already tried several times, still got same issues.

Then I try to delete/uninstall all spaceclaim and discovery R2. Next, re-extract the DISCOVERY_2021R2_WINX64, of course with "run as administrator", then re-install the file inside ( Discovery and Spaceclaim). 


After finish installation, I try to run the Discovery R2, still got same problem. But, the SpaceclaimR2 can open smoothly.
