I’m trying to install TotalSpaces2 (trial, downloaded today) and I get the following error message after I accept the terms, confirm the disk/destination, and press install. I have 7.5GB space remaining on my drive and I’m running 10.9.4 with admin privileges.

Hi, I’ve not seen this message before.
I just googled it (“SecurityAgent may only be invoked by Apple Software”) and it seems most answers mention that there may be some hard disk or hardware problem.
I think it could also be a corrupt download of TotalSpaces2. Perhaps, as a start, download the app again?
