I’ll assume this Tamino v4.2.1 that this is a Client only installation (Tamino tools only) that the module (MSVCR71.dll) is already defined in your PATH Assuming the above to be true, I believe the only way to correct this problem would be to: Reinstall the X-Tension Builder You need to go to Add/Remove Programs and modify the Tamino installation, by adding (reinstalling) the X-machine feature (tools).
