TestComplete displays this message if you are trying to save a copy of your project or project suite to a subfolder of the project’s or project suite’s current folder. To avoid issues, specify a different destination folder that is outside the project’s or project suite’s current folder.
For example, if your project suite is in the C:\TestComplete 15 Projects\ProjectSuite1 folder, you can save a copy of the project suite to the following locations:
C:\TestComplete 15 Projects\Copy of ProjectSuite1
C:\ProjectSuite1
and so on.
