I installed ADE 2.0 successfully on my XP SP3 notebook(Acer 5630Z).
When I start the program, an error message would occur, saying something like:
"Adobe Digital Editions 2.0 has encountered a problem and must be closed"
Perhaps there is a Windows service missing, but which?
A lot of people have been having similar issues on XP with ADE2.0 (as well as several other problems with it as well).
I suggest installing the older version 1.7.2 which seems more reliable.
Version 1.7.2, it is a little difficult to find, available on Adobe site for Windows and for Mac.
Thank you for the hint.
In fact, I was looking for a link to the old version, but all google results landed finally at version 2.0.
