Error! PlugIn Error: The required license is unavailable.Software & Version
Workbench 2025R1
*This example was taken from this version but is not necessarily limited to this version.
Description/Cause
This error occurs in 2025R1 because it is looking for the “rdpara” increment and that increment is not listed in the license file. This is a known issue with 2025R1 Pro and Premium licensing. This will be fixed in 2025R2.
*The cause(s)/solution(s) we identified in this documented instance may not be the only cause(s)/solution(s) for this error.
Solution
Solution 1 - Request Geometry Interface for Parasolid Temporary license
The “rdpara” license increment is included with the Geometry Interface for Parasolid license. Contact your account manager to request a temporary license.
Solution 2 - Revert back to 2024R2
Older versions of Workbench Pro/Premium do not look for the “rdpara” increment. You can revert back to the previous version you had prior to 2025R1 then wait until 2025R2 is released.
