Q: Removing Add-ins for SQL Server Management Studio I have SQL server 2008 R2 installed.
In the past I have installed the Redgate Sql Promprt 5 add-in. It doesn't work anymore, but I still have the menu in the SQL Management Studio. 
I don't see the add-in in the Programs and features list in windows 7, so I can't uninstall it. 
When I click on a command in the menu I get this message:

The Add-in supporting this command could not be loaded. Do you wish
  to remove the command?

When I choose "Yes" it removes only the selected command from the menu.
I want to completely remove the add-in from my Management Studio.
Where can I find the add-ins and where can I configure them in Management Studio 2008 R2?
If I need to remove some files to get rid of it, where could I find these files?
I looked in the installation folder and didn't find anything about add-ins...

A: I had same issue under 120. It seems Addins are now stored in Program Data. I renamed file but didn't help. I had to open/run SSMS in Administrator mode and this fixed it. Later I deleted the Addin from folder "C:\ProgramData\Microsoft\SQL Server Management Studio\12.0\Addins". May be you can try renaming the Addin with "_". That was the only difference in me renaming the file and SSMS in Admin mode renaming it.

A: And now for the correct answer
To remove all addin from SQL Server Management Studio. Delete all keys from:


*

*HKEY_LOCAL_MACHINE


*

*SOFTWARE


*

*Wow6432Node


*

*Microsoft


*

*Microsoft SQL Server


*

*100


*

*Tools


*

*Shell 


*

*AddIns











I didn't ask RedGate to slow down my SSMS with no way to disable it.

A: I had the same error when loading SQL Server, an Add-in from another related application was giving that error.  I didn't need that Add-in, but couldn't remove it.  Even removing from the registry (thanks for posting that by the way) didn't work for me.  I had to uninstall and reinstall the related application (Toad for SQL Server) and the "Add-in" was no longer an issue. 

A: I was using SSMS Tools but it kept autosaving my queries which I couldn't easily disable. Therefore I had to remove add in.
