Photoshop CC 2017 won’t open on my Mac.

I’d been receiving messages the past couple of months that my Adobe CC needed to be upgraded to function properly with the updates on my Mac. I’ve recently installed the latest iOS update and once it finished I noticed that the Photoshop program doesn’t want to open. 

 

I have the duo package of Photoshop and Lightroom–and while Lightroom functions and I can open it–Photoshop doesn’t seem to want to. I’m guessing that the reason this is is because my version of Photoshop, CC 2017, could still be a 32-bit app and needs to be upgraded to a 64-bit app? If I’m wrong about this, I apologize–this is all rather new to me, and I’ve not had any problems up until now. 

 

I’ve Googled the trouble-shooting procedures, but none of them seem to work. I couldn’t even uninstall the app because the file itself was too outdated to do so.

 

Is there anyone I can contact in order to get this issue resolved? I’m paying for my copy of Photoshop and I got it for a fair deal when it was being advertised several years ago, and I would hate to have to remove the applications entirely or pay more for an updated version.
