Have you checked what it says in http://helpx.adobe.com/digital-editions/kb/installing-digital-editions-20-windows.html ?
I think this is more about installation than running after installing, but ...???
I reverted to 1.7.2 because of other issues with v2.0; it has lots of bugs.
Did you want to use 2.0 because it is the latest, or is there some new feature in it you really want to use?
SJPT, I saw that link before posting here. Thanks though. That link doesn't address my issue but it would have been helpful when I installed 2.0 and it took me two days to figure out that the reason I couldn't run the program because Windows was blocking it. They should put this link on the download page.
I liked the new interface of 2.0 but since I primarly read on my Droid phone using a third party app (Aldiko), I guess it really doesn't matter what version I use. Thanks for the suggestion.
I'm having a similar issue using Windows 7. I can't uninstall/reinstall the program because it's my workstation and I don't have admin permissions.
