SharePoint 2010 Troubleshooting: Cannot uninstall Language Pack 0 because it is not deployed when uninstalling solution
Issue
Cannot uninstall Language Pack 0 because it is not deployed.
Solution:
Follow the below steps to resolve the issue.
- 1. Ensure to check the solution store (Central Administration --> System Settings --> Manage farm solutions) and see that the solution being updated was not deployed and has thrown an error. The error it gave was not able to do GAC deployment of the DLL. So I went to the GAC and uninstalled the WSPs related DLLs and deployed the WSPs again from Central Admin.
- 2. From services.msc, stop and restart the SharePoint 2010 Timer service and the SharePoint 2010 Administration service.
- 3. Ran the PowerShell command again. This time the WSP got updated.
