Bought a full version of LR6, tried to install it but got a message that it wouldn't work with Vista, I am running Windows 7 home premium. I read on the net to go into the files, right click setup and run as admin. I did this and the program loaded up fine, I now have a message at the top of my LR screen that says I have 29 days left in my trial period. This is a legal full version, what trial period is that referring to.
Found the answer to my problem, had to log out of adobe from within lightroom and log back in, was then prompted to reenter my numbers which I did. had to shut down light room and then shut down my computer and reboot. When I fired up light room after the reboot the trial information was gone.
