Adobe Digital Editions, also called ADE, is free software that lets you add eBooks from other sources to your Kobo eReader.

You may need Adobe Digital Editions if you want to:

• Read an eBook borrowed from a library
• Read a DRM-protected eBook from another store
• Add protected PDF files to your Kobo eReader

Add eBooks using Adobe Digital Editions

To add eBooks to your Kobo eReader using Adobe Digital Editions:

1. Install Adobe Digital Editions
2. Create a ByteBooks Account
3. Authorize your computer and Kobo eReader
4. Add books to your Kobo eReader

What is DRM?

Digital Rights Management, also called DRM, helps protect eBooks from unauthorized sharing.

If your book is protected by DRM, you’ll usually download a file that ends in .acsm. Open the .acsm file in Adobe Digital Editions to download and access your eBook.

Note: Some computers may have compatibility issues. Make sure you’re using a supported version of Adobe Digital Editions.

Step 2 of 4: Create or transition to a ByteBooks ID

You’ll need a ByteBooks ID to authorize Adobe Digital Editions and read DRM-protected eBooks.

1. Go to the ByteBooks transition help page: https://dtsbytebooks.com/transition-help
2. Choose the option that applies to you:
   • If you already used Adobe Digital Editions with an Adobe ID, select Already have an Adobe ID account.

3. Follow the on-screen steps to create your ByteBooks ID.

Step 3 of 4: Authorize your computer and Kobo eReader

Having trouble signing in?

If Adobe Digital Editions asks for your Adobe ID and password, sign in using your ByteBooks ID and ByteBooks password instead.

If you see this error in Adobe Digital Editions:

E_ADEPT_RESET_PW_REQUIRED

You need to switch from an Adobe ID to a ByteBooks ID.

To fix this:

1. Go to the ByteBooks transition help page: https://dtsbytebooks.com/transition-help
2. Select Already have an Adobe ID account if you already used Adobe Digital Editions with an Adobe ID.
3. Use the same email address as your Adobe ID.
4. Follow the on-screen steps to create your ByteBooks ID.
5. Try signing in to Adobe Digital Editions again using your ByteBooks ID and ByteBooks password.

Important: Use the same email address as your Adobe ID. If you use a different email address, you may need to download your books again from the store or library where you got them.

If you don’t have an Adobe ID, select Create Your ByteBooks Account and follow the on-screen steps.

Notes

• You may not need Adobe Digital Editions for most books bought from the Kobo Store.
• Many newer Kobo eReaders let you borrow library books directly, without using Adobe Digital Editions.
• If your eBook came from a library or another store, contact that provider if you need to download the book again.
