Problem: When opening Discovery products 2019 R2 via subscription license, you may receive the following license error:

ANSYSLI exited or could not read server port ANSYSLI_FNE_PORT

Cause: This is possibly because of an issue in retrieving the host ids from the system on ansysls_client.exe startup. To confirm this:

1. Type %temp% in Windows Search and locate .ansys folder.
2. Locate the file named ansysls_client.****.log
3. Open the file and check for error “Received a fatal signal C0000005: ACCESS VIOLATION”

Recommended Solution: Reboot the machine and if the problem persists, follow the steps listed below:

1. Go to folder C:Program FilesANSYS IncShared FilesLicensingwinx64
2. Rename the file ansysls_client.exe to ansysls_client.exe.old
3. Download the attached ansysls_client.exe file and paste it in the same folder.
4. Add a new environment variable ANSYSLS_CLIENT_USE_ALT_HOSITD_METHOD=1 to the list of system variables on your machine.
5. Reboot the machine

Note: This solution is applicable for 2019R2 version only and once 2019R3 is available, a complete uninstall and reinstall to 2019R3 is recommended.
