Challenge
When attempting to uninstall or upgrade Veeam Agent for Microsoft Windows, the Windows dialog box appears stating:
The feature you are trying to use is on a
network resource that is unavailable.
Click OK to try again, or enter an alternate path to a
folder containing the installation package
"Veeam_BR_Endpoint_x64.msi" in the box below.
Cause
This issue occurs when the original install msi is missing from the Windows Installer cache (C:\Windows\Installer).
Solution
To resolve this issue, the Veeam_B&R_Endpoint_x64.msi that matches the installed version of Veeam Agent for Microsoft Windows must be supplied to complete the uninstall.
Note: The installed build number can be found by opening the About page within the Main Menu (≡) of the Veeam Agent for Microsoft Windows console.
If you still possess the original VeamAgentWindows_x.x.x.x.exe installer that matches the installed version of Veeam Agent for Microsoft Windows, you can extract the Veeam_B&R_Endpoint_x64.msi from that exe using 7zip. (See example below.)
If you don't have a copy of the original exe-based installer, check the Veeam Downloads page to see if the installer for the version installed is available for download. If it is, download it and extract the Veeam_B&R_Endpoint_x64.msi from the exe-installer using 7zip.
More Information
It is highly unusual for an msi installer to go missing from the Installer cache. Many, but not all, situations where this issue occurs are related to the use of third-party "uninstaller" or "registry cleaner" applications. It's important to note that Microsoft does not endorse these third-party applications. Moreover, Veeam's software is not tested with these applications, and therefore, cannot predict the potential long-term negative impacts of their use. As a result, we strongly advise against using these applications to uninstall Veeam software or clean the registry of a machine where Veeam software is installed.
