I'm tying to upgrade our Nintex Workflow 2013 version from 126.96.36.199 to 188.8.131.52. While running the installer, I get the below errors;
How do I manually retract NintexWorkflow2013.wsp?
Make sure you are running the installer as an admin or a farm admin. To remove it manually you go to the Central Admin, System Settings, Farm Solutions under the solution management page.
This can also be done using PowerShell if necessary. But you should be able to do this from the CA site.
