Kobo Glo + Kobo Aura Authorization Troubleshooting

This appears to be an issue with Adobe 4.0. You get an ADE error message when attempting to move books from ADE to the KOBO. The solution is to use an older version of ADE. That means undoing everything done to set up the device, set up ADE and download and move books. The slate must be wiped clean and then all setup done again from the beginning, as before, but with Adobe 3.0 this time. The following steps should accomplish that.

1. Uninstall Adobe Digital Edition 4.0 (ADE 4.0) from your computer:
• Go to: Start > Control Panel > Programs.
• Click on Uninstall a Program (in Windows 7 or Vista).
• Select Adobe Digital Editions. Click Change/Remove to uninstall it. (In Windows 7 or Vista, click Uninstall.)
• Delete the Adobe Digital Editions folder (if present): C:\Program Files\Adobe\ or C:\Program Files (x86)\Adobe.

2. Install Adobe Digital Edition 3.0 (ADE 3.0) on your computer:
• (If you don’t have Adobe Flash installed, please install it now.)
• Visit the ADE website to download ADE 3.0 here .
• Click the download link for ADE 3.0.
• Once the download is complete, run the installer file.
• Follow the prompts in the setup wizard to complete the installation.
Make sure to leave the Associate .acsm and .epub file types option selected if you want to use ADE to read these types of eBooks.
• Click Done to exit the setup and launch ADE.

3. De-Authorize ADE on Your Computer:
• Open ADE.
• Press Ctrl + Shift + D on the keyboard.
• When prompted, click Erase Authorization.
• When the process is complete, click OK to close the dialog box and return to ADE.

4. Re-Authorize Your Computer with an Adobe ID:
• Open ADE.
• Click on Help > Authorize Computer to start the authorization process.
• If you have an Adobe ID, enter it along with your password.
• If you do not have an Adobe ID, click Create an Adobe ID to make one on Adobe’s website.
Once you’re done, return to the “Computer Authorization” dialog box and enter your Adobe ID and password.
• Click Authorize. Your computer is now authorized with your Adobe ID.

5. Download book to ADE:
• Click on FILE > Add to library.
• Double-click the title you’d like to add to ADE. It must be a title that you have not moved to any other device. It should appear on the Bookshelf in ADE.

6. Transfer a book to Your Kobo from ADE:
• Connect the Kobo to your computer. Wait until it is recognized.
• Open ADE on your computer. Make sure you’re in “Library” view.
Your eBook reader should show up under Devices in the left-hand column.
• Click on an eBook, then drag it over to your device.
Note: Transferring an eBook to your Kobo will automatically authorize the Kobo with the same OverDrive account or Adobe ID that your computer is authorized with.
• Once the transfer is complete, you can disconnect the Kobo in the usual way and open the book on your Kobo.
