Well, taking the second extension off didn't work, so I ran the entire ver7 upgrage again, including all the updates. 5 mins later I was still looking for the file.
This time I looked in C Windows ie7 updates\ KB953838-IE7 And lo, in there was the file! I felt the need to move it to the proper place, but a thought struck me. In KB etc, there are 49 files, mostly dlls What if the new copy needs these for all its new functions. The few that I've tried seem to work...the map and stuff like that. But what the Dickens is the other stuff for, and does a 'normal' copy of XL have that directory?
Sheeesh, since getting to Texas, I haven't done a thing but fight back a rain forest, and play with this computer. Book will never get writ.
