Issues and Workarounds
Non-Application Recovery Manager Issues Related to
Installation
• After installation of Application Recovery Manager A.06.00, Windows
may report that some application is not installed or that a reinstall is
required. The reason is an error in the Microsoft Installer upgrade
procedure. Please read the Microsoft Knowledge Base article
Q324906 to solve the problem.
• On rare occasions, Windows may incorrectly report free disk space for
an NTFS volume that is mounted at a directory on an NTFS
filesystem: instead of the NTFS volume free space the amount of free
space on the NTFS filesystem is reported. In such cases, if you try to
install Application Recovery Manager to the mounted NTFS volume,
the Application Recovery Manager Setup Wizard will not start the
installation if the amount of free space on the NTFS filesystem is
smaller than the minimum disk space installation requirement.
Workaround: free enough additional disk space on the NTFS
filesystem by removing unnecessary files.

Workaround: Install the Scrubber utility and run it. It will remove
obsolete storage nodes from the Registry. Note that a reboot of the
backup system is required afterwards. For more information on the
Scrubber utility, refer to the Microsoft support.
