"Virtual application does not exist" Error Un-registering an Application with SpoonReg.exe

Using SpoonReg.exe to unregister a virtual application

ERROR:
An error occurred while processing the command: Virtual application does not exist: pathtoapp.exe

A. Make sure that the virtual application is still installed in the current user profile

B. If the /allusers flag was used to register the application, use it in the un-registration as well. eg:
path\to\SpoonReg.exe /allusers path\to\app.exe
path\to\SpoonReg.exe /allusers /unregister path\to\app.exe

C. Verify that the path to the virtual application executable is correct

This error can typically mean one of three things:

1. The application is not installed on the current user profile
2. The application was installed to the All Users profile instead of the current user's profile
   
3. The path to the virtual application executable file is wrong
