Have successfully installed the Gen 8.6 Toolset installation.
Using Support Portal > My Entitlements for Site ID and "Gen - Workstation Toolset" > "Entitlement Details" the Licenses link/License Keys tab provides the FEATURE lines to create a ca.olf license file. That file has been placed into the License software directory "C:\Program Files (x86)\CA\SharedComponents\CA_LIC" per Gen Licensing.
However when using Gen Toolset option "Help > About Gen Toolset > System Info. > Licenses" it shows all the Licenses have Status as Expired.
The FEATURE lines all have date "31-DEC-35".
Gen 8.6 Workstation Toolset
The date format is incorrect and the year should be 4 digits i.e "31-DEC-2035".
The Licensing team explained that this is a known issue dating back to when CA systems migrated to Broadcom systems. Those keys were auto-generated by the system.
Editing the file to have 4 digit years should resolve the problem.
