Codecoverage.exe does not generate output xml

In order to import a coverage file to SonarQube, I'm executing CodeCoverage.exe to convert a ".coverage" file to xml. I execute a cmd line like: CodeCoverage.exe analyze /output:[name of xml file to be generated] [name of the coverage binary file].coverage but I do not get any output xml and no errors. I must say that I was able to generate such xml for tests of other solution files. What can be the problem? How can I troubleshoot it?

Thanks!
