Thank you for your post.
I am unable to replicate the problem on a number of Macs running Mac OS X 10.7.4.
Since reinstalling didn't work, it could be a bad download of the application.
Did you purchase this electronically? If so, then download a fresh copy of FileMaker Pro 12 and run the installation again. If you purchased a CD, contact the FileMaker office nearest you for a replacement CD.
Keep me updated with any progress.
I downloaded from your web, twice, with the same result. Initially I installed the demo version, then purchased this promo deal. When I recieved the email confirming my purchase I used the link to download the software. This link I used again on the second download.
Is there a special way to uninstall the software, prior to installing again.
Best wishes C
