CRITICAL ADVISORY

Potential Data Loss When Uninstalling Loupe Cell Browser 1.0.1/1.0.2 for Windows

Release Date: April 4, 2017
Severity: Critical

Summary

Due to an issue in a third-party uninstaller component that shipped with Loupe Cell Browser 1.0.1 and 1.0.2 for Windows, the uninstallation process may delete unintended files if the user installed Loupe Cell Browser into a non-default location.

If you have installed Loupe Cell Browser 1.0.1 or 1.0.2 for Windows, do NOT run the uninstaller, either through the Control Panel or by running the "Uninstall Loupe Cell Browser" program. See below for details on how to safely delete Loupe Cell Browser 1.0.1/1.0.2 and upgrade to a new version.

Affected Products

Loupe Cell Browser 1.0.0 for Windows is not affected. The Mac versions are also not affected.

Details

When the Loupe Cell Browser 1.0.1/1.0.2 for Windows uninstaller runs, it deletes the folder in which Loupe Cell Browser was installed, including all of its contents. If the user installed Loupe Cell Browser into the default folder specified by the installer, C:\Program Files\Loupe Cell Browser, then the uninstaller deletes this folder. This is the expected, normal behavior, and there is no risk of data loss in this case.

However, if the user overrode the default location and selected a pre-existing folder during the installation process, then that folder will be deleted by the uninstaller. Any other non-Loupe Cell Browser files or folders within that preexisting folder will also be deleted. The files are deleted in such a way that they cannot be recovered by the Recycle Bin. If the user has not backed up the files within this folder, they will not be recoverable.

Recommended Actions

If you have an affected product installed:

Software Fix

We have addressed this issue and incorporated a fixed uninstaller into a new 1.0.3 release of Loupe Cell Browser for Windows. Going forward, please use only Loupe Cell Browser 1.0.3 for Windows or later to avoid this potential issue.

It is important to note that installing version 1.0.3 does not, by itself, remove the risk of unintentional file deletion. You must follow the steps above in "Recommended Actions" to disable the uninstaller from versions 1.0.1 and 1.0.2.
