Without knowing "some of them threw errors" means, not much can be advised.
There have been some changes (command barRibbon, the way graphics are dealt
with..), but how these impact your code, only you can tell.

I ran several old programs, but some of them threw errors. So sounds
like that's really bad.
If so, upgrading to Excel is going to be painful.
