I am attempting to trial a standalone version of LR5.5. I have been using aperture but have heard that this program is on life support. So I thought I would give LR a test drive. So far, not so good. I installed the trial but keep getting "An error occurred when attempting to change modules." I have tried uninstalling to no avail and a few things from the web like starting a new catalogue. I tried to late preferences in my applications support but it does not seem to be there. I tried to see if it was hidden but still could not find it. No sense in buying if I cannot get it to run. This problem seems a bit unusual to me. I have never installed any software on my Mac pro and ran into an issue that would not all me to use the program. I hope there is an easy solution to this.
Tried removing preferences in library and restarting but it did not fix issue
