How to uninstall Patch Manager

There are occasions where you may need to completely uninstall  Patch Manager and SQL express (if used). Simply uninstalling it from programs and features is not enough. This article will walk you through removing the patch manager and its files and registry keys.

If you wish to remove licensing as well, do this first before the uninstall.
Use the Start Menu > SolarWinds > SolarWinds Licensing app to deactivate the license if needed.

1. Open Control Panel>programs and features. Uninstall Solarwinds Patch Manager V.....
Uninstall SolarWinds Client Components.

2. If SQL Express is used for the EminentWare database, you will need to verify the Eminentware database was removed by the Patch Manager uninstall, or uninstall SQL Express from Programs and Features as well.

The database instance will be labeled MSSQL, SolarWinds Orion (Verify that instance does not support any other database other than eminentware). You can use tools like SQL Management Studio to verify this, or check the default database location (typically <installdrive>:\Program Files\Microsoft SQL Server\MSSQL##.SQLEXPRESS\MSSQL\DATA  (the ## depends on the verison of SQL Express).

3. Open the C: drive and delete the following if Patch Manager is the only Solarwinds product installed on the server. (Drive letters may vary depending on your original installation).
C:\ProgramData\SolarWinds
E:\Program Files (x86)\SolarWinds
If there are other Solarwinds products on the server uninstall the following. 
C:\ProgramData\SolarWinds\Logs\PM
E:\Program Files (x86)\SolarWinds\Patch Manager

4, Open the Registry delete the following key (entire folder)

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\EminentWare

5. Confirm that the Eminentware database has been deleted. If the Eminentware database still exists, deleted the database. The new install will require the exact same name, and it should be created by the PM Configuration Wizard during installation. Please don't manually create a database.  Also, verify that the actual database files are deleted from the data drive location (varies by installation).

6. If you are completely removing Patch Manager permanently, also delete the following registry keys (entire folder):

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Solarwinds\Licensing\Patch Manager
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\EminentWare

This will wipe the License key. If you are going to re-install, DO NOT delete these folders.

7. Reboot the Server

9. If you are getting a license error during the initial software installation during an upgrade, you may need to use the License Reset Utility, which can be obtained from support or via the Customer Portal.
