- No license found: to work with Xpress Kalis for Mosel, the Xpress licensing system, and the kalis module must be installed. You need to copy the license file that you will receive from your software vendor into the Xpress installation directory and set the environment variable XPAUTH_PATH to point to this directory.
- The Xpress Kalis module is not found: if the file kalis.dso is not installed in the directory dso of the Mosel distribution, then the environment variable MOSEL_DSO must be defined with the location of this file.
