Sorry if this is a stupid question or has been asked before but I couldn't find anything in the search...

Can I run Desktop Manager 3.6 and the latest 4.1 on the same PC? I ran into errors one time by having 3.6 and 4.0 installed simultaneously.

I don't want to get rid of 3.6 because it allows you to edit your Address Book IPD files directly from the app. I don't know why they've removed it for 4.0 and up?

Any help is appreciated! Thanks!
