Below is a way of manually installing GuideGuide version 3.2.3 into Photoshop CS6 (it is assumed that the same method will work with other versions (for example, CC), but here, mostly, we are dealing with CS6 only).

Sometimes, Adobe Extension Manager will not install an extension.

INSTRUCTIONS FOR MANUAL INSTALLATION OF GUIDEGUIDE (version 3.2.3) into Photoshop CS6 (and, possibly, other versions of Photoshop) Nor do I ever use Windows, so the instructions for a Windows installation may need a little alteration also. However, I can only speak from my own experience, and I do not use CC. 2.3 in CS6 at least (and, very likely, in CC also. I can guarantee that, if these instructions are followed, you will be able to install G.G. Below, I am pasting in the document that I composed for others with the same problem. However, there is a snag that can throw anyone, as it threw me at first. Anyway, essentially, the procedure for v 3.2.3 is essentially the same as that for 2.1.4. That was when I posted on this forum, for ideas that would help. 3.2.3, I tried to install this in the same way as before. I did this, and, after making little alterations (in CS6, the folders were a bit different), it worked (I am using a Mac, by the way). I had given up on ever installing it, but thankfully, a correspondent somewhere in this forum (the thread is over two years old, and I have since looked for it, and cannot find it) stated how manually to install GuideGuide 2.1.4. The xzp installer that it mentions failed, just as Adobe Extension Manager, to install GuideGuide. I did consult the document (previously), and, although it is the official answer, it did not solve my problem.
