Symptoms
In an isolation environment, uninstalling isolated applications, using Installation Manager, may not remove all files.
Causes
A component or file is open during uninstall.
The files, usually zero-byte, are deleted file markers created by the isolation environments to track deleted files.
Resolution
Manually remove these files. This can be done when there are no active sessions for applications running in the isolation environment. Launch Windows Explorer or a command window outside the isolation environment and delete the offending files. After uninstallation of an isolated application, it is safe (and a best practice) to delete related application files or artefacts that remain in the isolation environment.
