I have downloaded the most recent executable from your website and installed it on my PC. Nothing seems to happen when I try to launch the program.
I have searched the forum for a solution and can see that this has been an issue for at least 3 years (maybe even 10+ years). I have personally had the issue for at least one year. When I read through the comments, no one has ever been able to resolve this issue. When can we expect to be able to read our ACSM encoded e-books?
I have tried the following as per advice in forum:
My windows spec:
Hello friend, don't waste your time trying to fix the ADE (the problem is more than 10 years old), better install the Bluefire Reader for Windows. With the same Adobe account it can be activated.
Had similar issue, all I could do was find a random old link to edition 4.0 and install that. Seems to work so far, touch wood. Follow these instructions: https://helpx.adobe.com/au/digital-editions/kb/cant-install-digital-editions.html
It worked for me to change the installation directory. See the following link on this same site.
