Photoshop: Error: Extension not properly signed on start-up

CC keeps telling me " the extension could not be loaded because it was not properly signed" Why? Also when I go to contact Adobe, I get directed to the Danish site, again Why?

See this document for troubleshooting: https://helpx.adobe.com/photoshop/kb/extension-not-properly-signed.html

Note: You can see what extensions are installed and the path to those extensions by selecting Help > System Info... (scroll to the bottom. Extensions are listed last).

Sounds like uninstall/reinstall fixed this.

Yes, but created another problem with CS6, can't get CS6 to update apparently update is checking CC rather than CS6

I uninstalled it, and downloaded another copy from prodesigntools.com and now it works perfectly. Try that.

Also, when updating, let it update directly from photoshop itself, dont download offline updates.

I have disabled the libraries panel from Window > Libraries and the error is gone.

I didn't have to disable anything, just reinstalled it with a fresh copy of cc from prosesigntools.com and it worked flawless
