When you launch Adobe Digital Editions 1.x on Windows, you are asked to authorize the product. Then, the error "E_ACT_TOO_MANY_ACTIVATIONS" occurs, indicating that all of the authorizations allowed for Adobe Digital Editions on that machine have been used.
In some cases, you don't receive the error, but run out of activations after switching machines or replacing hardware.
Use the following workaround to allow your machine to launch Adobe Digital Editions 1.x. If you received the error "E_ACT_TOO_MANY_ACTIVATIONS or Adobe Activation Request Error 2004," contact us to have the activation count reset.
If possible, generate a System info file before you contact us (see instructions below). Adobe uses this file to help find a common element that's causing this issue for all Adobe Digital Editions users.

The root cause of this issue is something installed in your user profile that affects Adobe Digital Editions. While there is a temporary workaround, it is in your best interest to troubleshoot your machine to determine the cause and resolve the issue.

If Adobe Digital Editions launches without requesting activation, then you know that one of the startup items is the root cause. You can then selectively disable startup items and retest to determine which startup item is the problem.
