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.
Note: It is helpful to note (in your case submission) the brand of your machine, plus any spyware, malware, or security tools that are installed. For example, if you have any McAfee products installed, or spyware tools such as Lavasoft's Ad-aware.
Generate a Windows XP System info file:
Choose Start menu > Programs > Accessories > System Tools > System Information.
In the System Information menu, choose File > Save.
Save the system information as a system information file. Windows exports an .NFO file.
Put the .NFO file inside a .ZIP archive and attach it to the web case when you open the case.
If you have trouble creating a ZIP archive, you can FTP the file to Adobe Support. See www.adobe.com/support/crm_portal/ssi/ftpinfo.html for more information.
Note: The system information file can contain information that is not relevant to this issue and that you do not want to share with Adobe. If so, exclude that information from the file that you send.
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 computer to determine the cause and resolve the issue.
To troubleshoot, use the procedures in Disable startup items and services (Windows XP) (kb404984). Disable all startup items, and then restart and launch Adobe Digital Editions. 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.
While troubleshooting, use a workaround to run Adobe Digital Editions to read eBook content. You can also use this workaround if you do not want to troubleshoot.
To temporarily work around this issue, do the following:
Open a support case and have your authorization count reset if necessary.
Select Start > Control Panel.
Double-click User Accounts.
Log out of your primary account.
Log in to the new user account.
Launch Internet Explorer. If you prefer to use another browser, such as Mozilla Firefox, it's sometimes necessary to reinstall that browser in the new user account.
Launch and authorize Adobe Digital Editions using the same Adobe ID you used on the other account.
