Installing Kobo on a tablet and problems with Adobe digital editions.

Report · Jun 07, 2015

I have just installed kobo on my tablet. I cannot transfer books from my local library to my tablet. It says Error! Check activation. It says that my table has been authorized. I tried to erase the authorization but it won't let me. The Adobe digital stops working! It is driving me to distraction. On another note, I have been having trouble trying to reinstall Kobo to my Kobo ereader and there is also a fault, of which I have contacted Kobo and still no solution found.

If due to some reason, you are unable to deauthorize ADE, follow the below steps:

Mac:

1. Go-> Go to folder.

Go to folder dialog will appear.

2. Type ~/Library/Application Support/Adobe/Digital Editions

drag the activation.dat file to the trash.

ADE will be deauthorized now.

Now Authorize ADE again [Help -> Authorize Computer].

Windows:

Choose Start > Run.

In the Open text box, type regedit and then press Enter. The Registry Editor opens.

In the left pane of the Registry Editor, locate the following registry key:

HKEY_CURRENT_USER\Software\Adobe\Adept

Right-click the Adept key and choose Delete.

In the Confirm Key Delete dialog, click OK.

Your authorization will be deleted.

ADE will be deauthorized now.

Now Authorize ADE again. [Help -> Authorize Computer].

I have tried all this to no avail. I have even tried it on my tablet. It always stops at this:

Execute: "C:\Program Files\Kobo\vcredist_x86.exe" /q

I had this problem on Windows. It was sorted by deleting the Registry entry key which held the authorisation. I am afraid someone else did it for me, so I can't give you instructions on how to do it.
