This error:

occurs for bot the base and HPC 2025.3.1 toolkits, and the earlier hpc kits are not available. It occurs with and without cli installation, and even with h--ignore-errors:

This was a bogus error message. When I installed into fresh directories it worked fine. Claude.ai helped me figure this out.
