Unable to Launch Adobe Digital Editions 4.5.11

So after spending some time looking for a fix, I could only find a workarround solution. Just to give a general picture of my issue with ADE

- I have ADE running for almost 1 year. I use it basicaly to study ebooks generated on this platform (if I could only have a choice ...)  These ebooks requires ADE ID registration to work. 

- All of the sudden the application stopped working this weekend (June'20). 

- Tried to uninstall/reinstall/reboot and no luck. ADE wouldn't start, giving no hint neither error message of what was going on. 

Workarround solution

- Step 1- Remove ADE 4.5

- Step 2 - Download and  install ADE to 4.0, using the install zip provided at this link:

-  Step 3 - (Required in my case, as after installation, I was able to access the App but the following error message showed up: "Error! Check Activation.") Reset ADE ID. To do that, go to Help -> Remove Authorization . After that Add a new authorization with your credentials. 

Things seem to be working and I can go back to my chambers and study. 

I also found a link (for those who believe a workarround is not enough, and want to keep wasting time) to play with windows registriy...

Thaks Adobe for developing a crappy App with no support.
