Failed migration due to access restrictions

Issue

Error on rename ... (Errcode: 13)

Cause

If you see this error, a migration failed during Contrast startup. The failure was most likely caused by the current user having insufficient privileges to modify files in the directory in which Contrast was installed.

Resolution

To resolve the issue, uninstall Contrast and delete the remaining data files. You can then either elevate the user's permissions in the installation directory or choose a new directory where the user has full privileges. While it's uncommon, Administrator users can encounter this problem if there are extra file restrictions put in place by your organization.
