sitting at a client's computer.
The Install Plugin Script Step always errors with error 1551.
We tried a lot of things. Same script works on other machines fine.
But here we always get the error. Manually deleted plugin and same error.
What could go wrong there?
As we are clueless, please change Install Plugin Script Step to provide error message for Get ( LastExternalErrorDetail ), so we can have a textual message on what exactly failed.
