LDRA Test tools: Invalid CTL file

10-Jun-2026

If you get an error that the CTL file is invalid:

1. Check that the version and language match the installation.

2. Make sure the CTL file has not been altered; improper editing of this file will invalidate it. 

If the issue remains, send the CTL file to Technical support and include the version of LDRA  you have installed and the language, e.g., 9.4.3 C/C++.
