Check if your Firewall anything blocked. Better you add Digital Edition as sure program.
Thank you for replying.
I've change another formatted ebook. Then the error was dismissed.
I don't know what's the cause. But I'm annoying that update dialog pops up at startup...
The error with the update seems a error with the permissions of the user.
Thank you for answering again :-)
You're right. I haven't seen the error when I started up the application as an administrator.
After that, however, I still get the update popup when I start the application as an ordinary user.
I will use to read books with the popup for the time being ;-(
Right click on Digital Edition.
Choose settings and compatibility.
Set the check for run as admin.
Now click on Okey.
now start the program again
