I am trying to run a model I've built and used successfully on my Mac for several years; I recently bought a PC with the new AMD 32-core chip and am trying to run it there.
My parfor loop is used to run many different simulations at the same time, all of which use readtable on the same set of input spreadsheets in order to read input data to the simulation.
The simulation is continually crashing on the readtable lines, with 'internal error' or other messages.
I know that the excel interaction is different on a PC than a Mac, but is there a different program structure I should be applying? Should I use readtable differently, or not at all?

Try using READTABLE with the 'UseExcel',false parameter. (This might also be 'Basic',true in older releases.)
