Using ACAD 2012, Windows 7, 64-bit

I'm having a little problem...

I have a number of .lsp routines that I have loaded into the startup suite. I have them pathed correctly and at the top of the list in the support file search path under options.

Problem is...they load into the drawing when a drawing is opened, but they will not execute. If I type APPLOAD and re-load them individually, they all seem to work fine.

I'm only having this problem with the computers that are running 2012 in the office

Any help is greatly appreciated
