@WayneSchulz, I'm pretty sure that's not the case anymore. Up until a couple/few years ago, you had to have the prior IRD's installed before installing the latest IRD. But now that doesn't appear to apply, as it's not mentioned in Sage's year-end doc. Only problem with looking in the Sys Act Log is that you have to wait an eon for it to appear on-screen, so most often I'll instead pull that file into Crystal/Excel. I agree @JeffSchwenk, that's too logical to have it show in the Installed Modules Listing.
