Dredging this up from the past... What I can say is that I have 2 versions of CAESAR loaded... 2017 (build 160721) and 2014, and the experience is the same between the two, across all CAESAR files. Whenever I get to the point to select a CAESAR (or _P) file to pull loads from, I get an Out of Memory error.

Unfortunately, I cannot pinpoint a specific action that resulted in CAESAR to start acting this way.

All I can guess is that there's some registry setting or temporary files that gets removed if you un-install, and then gets reset to default when you install it, but doesn't get over-written if you install on top of the last CAESAR install.

I've attached an example file, but I'm doubtful it'll reveal anything.
