Hi Scott,

The issue is due to a newer version of OpenSSL on the Windows machine which places conflicting libraries like libcrypto-1_1-x64.dll and libssl-1_1-x64.dll under C:\Windows\System32
This common Windows path is always loaded on the PATH variable and conflicts with the ANSYS install of OpenSSL under the ANSYS install path.

Solution is to rename the following dll files to .dll_backup under C:\Windows\System32:

libcrypto-1_1-x64.dll

libssl-1_1-x64.dll
