Reinstalling the ShadowSnap software

Follow

Scope

This article explains how to use Revo Uninstaller and PsExec to remove and reinstall the ShadowSnap software.

Revo Uninstaller and PsExec are not supported by Datto, but they have produced reliable results. 
This process requires several reboots of the production machine.
This article only applies to the ShadowSnap agent. This process is inapplicable to any other agent type. To reinstall the Datto Windows Agent, Datto Mac Agent, or Datto Linux Agent, please use their built-in uninstall and reinstall utilities.

Background

Revo Unistaller Pro is not always necessary, but we recommended it because it ensures all files and registry entries that are associated with the installation of ShadowSnap and ShadowProtect are completely removed.

An alternate but less-comprehensive method to remove ShadowSnap and ShadowProtect would be through the Add/Remove Programs wizard located in the Windows control panel.

Prerequisites

1. Reboot the production machine.

2. After the reboot, verify that the following services are present and running:

  • ShadowProtect Service
  • StorageCraft Raw Agent
  • StorageCraft Shadow Copy Provider

If any of these services are not present or in a running state, this is a sign of a corrupt ShadowSnap install. Follow the process described in this article to resolve the issue.

Using PsExec To Install The ShadowSnap Software

Disable all antivirus software running on the production machine before running the ShadowSnap installer. This will ensure that the software installs correctly, and with all required permissions.

1. Download the full suite of PsTools software (about 1.6 MB) from Microsoft.
2. Download the ShadowSnap agent from the ShadowSnap section of the Datto Downloads page.
3. Extract the zip file to the production machine's desktop.
4. Make note of the path of the ShadowSnap installer.
5. Go to "Run" and type cmd to open a command window. If you are using domain accounts to install the ShadowSnap software, open the first command prompt using the Run As option, and uncheck the option to restrict access.

6. Navigate to the directory where you downloaded PsExec:

cd Desktop\PsTools

psexec.exe -hsi cmd.exe
