So if you don't want to keep 151 on your computer you can just do that update and 151 will be removed.
If you want to have both builds on your computer follow my instructions.
This is great news for those with a Mac as I wasn't sure how to get that problem fixed. (Hey, I've bought cartridges to help people with their problems. I even bought an Imagine so I could help. But I draw the line at a new computer!!! At least while mine is working fine....) (Never say never, right!)
Thanks for letting me know Colleen!
