I 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:

Hi 

Suggested Solution:

1. Check for the following files in the system directory:

   • C:\Windows\System32\libcrypto-1_1-x64.dll
   • C:\Windows\System32\libssl-1_1-x64.dll

2. If these files exist, rename them to:

   • C:\Windows\System32\libcrypto-1_1-x64.dll.safe
   • C:\Windows\System32\libssl-1_1-x64.dll.safe

3. After renaming the files, try launching CFX again.
