I just installed 16.6 on my computer under the assumption I could still launch 16.3. 16.6 is up and running as anticipated, however if I try to launch 16.3 I get the following error.
"The program can't start because cdn_xerces-c_2_7.dll is missing from your computer. Try reinstalling to fix this problem."
Did the install of 16.6 delete or move this .dll? Should I reinstall 16.3? Any guidance would be greatly appreciated.
You need to use the switch release feature to switch the licensing between 16.6 and 16.3.
