Are structured keywords ever going to be supported in Windows? A couple of months ago it looked like they would be and that it was a priority but I still haven't seen anything on it.
It was my highest priority for version 4.5.2. I completed it a number of days ago and it has appeared in the currently available 4.5.2 beta. See the Announcements section for details on how to obtain the beta.
The other question is how do I know for sure that I have 4.5.1.1 installed? I have tried help about and it just keeps saying 4.5 after the install of 4.5.1.1.
Then you are still executing the 4.5 version even though you now have the 4.5.1.1 version installed. This mostly happens on Windows. Here is what I recommend you do. Use the Add/Remove programs control panel to uninstall Photo Mechanic until there is no Photo Mechanic left on your system. Restart your system. Then reinstall 4.5.1.1.
Now there should only be 4.5.1.1 on your system.
