Environment

All supported DevTest releases and platforms.

Cause

Check if the installer has uninstalled the old jars from the $DEVTEST_HOME/lib/dradis folder.
File or folder permissions may have prevented that.

Resolution

Verify that the user running the installer has the correct permission to access all files and folders in the DevTest installation.
After adjusting the permissions, rerun the installer.
