SubscriberI have been trying to fix this error for 2 days but can't figure it out I uninstalled and installed ansys 3 times but no luck, tried deleting the .cfx folder, and .ansys files but nothing seems to work, I'm trying to open results in CFX from the WB, but it keeps popping the error, the standalone version works if I lauch it outside of WB but anything CFX related inside WB doesn't work. Error:

Ansys EmployeeHi
Suggested Solution:
Check for the following files in the system directory:
C:\Windows\System32\libcrypto-1_1-x64.dllC:\Windows\System32\libssl-1_1-x64.dll
If these files exist, rename them to:
C:\Windows\System32\libcrypto-1_1-x64.dll.safeC:\Windows\System32\libssl-1_1-x64.dll.safe
After renaming the files, try launching CFX again.

SubscriberHi, I am facing the same issue. I don't find these files in the folder mentioned. I have tried all possible measures to resolve this issue using whatever fix was recommended. It doesn't solve, however. Kindly help. I am able to open CFX in standalone mode, but it doesn't open from Workbench, and I would highly appreciate it if I could do that.
