An error occurred while signing: SignTool.exe not found

Question

While I was trying to Update my Project I was making - I got an error for the first time I\'ve seen:

\'An error occurred while signing: SignTool.exe n

Answer 1

I had the same issue/error message just after upgrading Visual Studio Pro 2019 V16.6.0. Solution was to make sure that the signing certificate is valid as mine had expired by a day.

Look in properties and signing to either enter a valid or temporary certificate. To keep the file name the same as before then un-click the security as mentioned above and then delete the key file linked to the programme.

Create a new key file and then add back the security.
