For those Linux users having trouble installing ADE 2.01 in Wine, I have just posted a Howto on the Wiki. You can find it at:
https://wiki.mobileread.com/wiki/ADE_2.0.1_Linux
It worked for me. However, I already had it working following a much more convuluted procedure. As I had removed the existing version and the steps install into a totally different wineprefix in any event, this should not make a difference. In theory at least.
I am running Sabayon with the latest version of Wine. The program runs and I was able to authorise it with Adobe, drag and drop .acsm files and download and read the books. I've got a warning on the howto which I intend to leave until others have tested and verified it. Wine is a strangte and wornderful creature, and there is of course the potential to break your installation.
If you do want to try it please post you success or failure and any feedback on this thread.
