KB483982: An error is experienced when uninstalling MicroStrategy Workstation

Description 

When uninstalling Strategy Desktop or Workstation, you may experience the following error:

Why is this happening? 

If you have installed Strategy 2019 or previous versions of Platform prior to installing Desktop/Workstation, and then uninstalled Strategy 2019, it will remove a registry key required for uninstalling Desktop/Workstation.
In an ideal scenario, this registry key can be found at

Computer\\HKEY_LOCAL_MACHINE\\SOFTWARE\\Strategy\\DSS Suite\\StrategyWorkstation.

If this registry key is missing, the above error message will appear during the uninstall process of Workstation/Desktop. 

Workaround

The installer looks for entry "Version" in the "StrategyWorkstation" or "StrategyDesktop" registry key. To recreate the missing key, you need to create a few parent keys first. It is likely that your current machine will only have

HKEY_LOCAL_MACHINE\\SOFTWARE.

• Right-click on SOFTWARE > New > Key. 
• Name this new key "Strategy."
  

• Right-click on Strategy > New > Key.
• Name this new key "SS Suite."
  

• Right-click on DSS Suite > New > Key.
• Name this new key "StrategyWorkstation" (or "StrategyDesktop" if using Desktop).
  

• Right-click anywhere in the right pane and select New > String Value.
• Name this new string value "Version."
  

• To find the version number of your current Strategy Workstation/Desktop, go to Add/Remove Programs in the Control Panel. The version number can be found in the Version column.
  

• Alternatively, you can open Workstation/Desktop and choose Help > About Strategy Workstation.
  

• Make sure to enter the version number exactly as it displayed to the registry entry "Version." To edit the version, double-click on it and enter the value.
  

• Proceed with uninstalling Strategy Workstation/Desktop.
