I have been using Adobe Configurator for years, creating extensions for Photoshop CS6 and I've never had an issue.
Today I have gone in to create some updates to an extension that I have been running for years in CS6 and I get the following error when I attempt to export the .zxp file. I have also changed computers, to the one I originally created the extension on to see if there was something funny going on with my computer, but I got the same error.
For the life of me I cannot understand why this error is appearing, and it has nothing to do with passwords.
Does anyone here have any idea what the issue is. I have seen it in other forums with no clear answers.
Unfortunately, The Configurator 4 discontinued a few years ago and timestamping mechanism stop to work last year. However, We can make package and sign manually.
