Sorry, had read the details of the text file and saw that it implied that my ‘publisher’ field was incorrect. To clarify the contents are :
Done Adding Additional Store
Error information: "Error: SignerSign() failed." (-2147024885/0x8007000b)
SignTool Error: An unexpected internal error has occurred.
Thanks for the common cases link - I can see that the publisher didn’t match (I was missing the ‘O=’ section). Editing that to match will hopefully sort it.
Regarding the automatic certificate generation - I’m on the latest commit, but I don’t see the option in the project settings UI. Any reason it wouldn’t be available to me?
