Adobe digital edition dont open anymore

[Laurence26508895yt3g]

I had problems opening my Adobe Digital Edition 4.5 and read books on the last 3 days, so I read that I have to desinstall and reinstall Adobe Digital Edition on my PC, wich I did, but it doesn't work, the programm now just dont open anymore. 

Could you please help me??  I am in the middle of my master degree and need to be able to have acces to the book I had bought. 

Thank you.

I've been tackling this problem for a few months now.  Very frustrating.  I finally got Digital Editions 4.5.11 to work on my Windows 10 computer today.  Here is the method I used:

1. de-authorise Adobe Digital Editions - Open Digital Editions, ctrl+shift+d to de-authorise installation

2. close the application

3. find Adobe Digital Editions application file in File Explorer - mine was in C:\Program Files (x86)\Adobe

4. open Adobe Digital Editions folder and use 'uninstall'

5. find all other copies of ADE_4.5_Installer.exe or ADE_3.0_Installer.exe on computer hard drive and delete

6. download ADE_4.5_Installer.exe from https://www.adobe.com/au/solutions/ebook/digital-editions/download.html

7. install in folder C:\Program Files (x86) NOT C:\Program Files (x86)\Adobe

8. copy  .acsm file for book borrowed through ProQuest to C:\Program Files (x86)\Adobe Digital Editions 4.5 and C:\Program Files (x86)\Adobe Digital Editions 4.5\resources

9. authorise freshly installed Adobe Digital Editions application

10. open Digital Editions

11. File>Add to Library> select .acsm file from Digital Editions 4.5 folder or Digital Editions 4.5\resources folder

12. Book should now open and Digital Editions 4.5 should work properly.

**edit** - I wrote the above for the librarian at my uni. My uni library uses ProQuest for downloading .acsm (Digital Editions ebook) files.  You may get your Digital Editions e-book .acsm files from 'wherever' you usually get them - shouldn't make a difference.

Hello, I did everything until the step 8. I bought my books in Kobo, I
dont understand where to find the .acsm file book and where to copy them.
Coule you please help me for that?

8. copy .acsm file for book borrowed through ProQuest to C:\Program Files
(x86)\Adobe Digital Editions 4.5 and C:\Program Files (x86)\Adobe Digital
Editions 4.5\resources

Thank you.
