When you activate Adobe Digital Editions, do you receive an error? If so, try the solutions on this page to resolve the issue.
Solved: I need activation code for our Photoshop CS2. This is what we have used for years and it is actually not more than that we need. Are trying to install - 10480453. The activation request is automatically sent to Macromedia backend servers via the internet using an HTTP request with SSL encryption. If the request is valid, a response code, which automatically unlocks (activates) the software, is sent to your computer. The registry cleaner found a few 'adobe entries' and I let it fix those specific to Acrobat but left the ones that seemed 'common', like the updater, alone. CCleaner too left the entry in the 'start menu' behind but I ignored it. I must say that I'm impressed by the Adobe cleaning tool! Next, I restarted and ran the original installer.

Troubleshooting reauthorization and deauthorization issues on Windows
Note:
The following task requires you to modify the Windows registry. The registry contains system-related information critical to your computer and applications. Before you modify the registry, create a backup copy. Adobe does not provide support for problems that arise from improper modification of the registry.
For more information about the Windows registry or the Registry Editor, see the Microsoft Support site.
If the deauthorizing process is unsuccessful on Windows, it is possible to modify the registry to remove the activation information.
- Close all applications.
- 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 registry key, HKEY_CURRENT_USERSoftwareAdobeAdept
- Select the Adept key.
- Choose File > Export.
- In the Export Registry File dialog box, select Selected Branch under Export Range. Enter a name and location for the backup registry key. Click Save.
- Right-click the Adept key and choose Delete.
- In the Confirm Key Delete dialog, click OK.
- Close the Registry Editor.
- Open Adobe Digital Editions and reauthorize.
This error may occur when you activate Adobe Digital Editions or read epubs.
To resolve this issue, make sure that the machine’s system time, date, and time zone matches the time/date/zone when you purchased the PDF or epub.
When you download a PDF or epub, the Adobe activation server records the timestamp. This information is stored inside the book. When you open the book, this information is compared to your current system’s information. If your system has an incorrect time/date/time zone, the activation server ignores the request and you cannot read the book.
One of the following system settings (or a combination of them) causes this error:
- Incorrect clock time
- Incorrect date
- Incorrect time zone
This error may occur if you have initially activated Adobe Digital Editions as an anonymous user, and are now trying to associate an Adobe ID with that anonymous activation.
To fix this issue, you can take one of the following actions:
Delete the anonymous activation (on Windows: Ctrl-Shift-D, on Mac: Cmd-Shift-D) , and authorize Adobe Digital Editions with your current Adobe ID.
Note:
Taking the above action means that any current books that you have in Adobe Digital Editions are no longer available to you.
OR
Create a new AdobeID, and use the new ID to authorize your account.
Note:
Taking the above action ensures that your current content is still readable on your computer, however you may have to reauthorize your e-reader device to the Adobe ID.

Adobe will end support of Flash Player on December 31, 2020. Here's what you can expect in the meantime for each Microsoft browser:
In the next version of Microsoft Edge (built on Chromium), Flash will be disabled by default. However, users may re-enable it on a site-by-site basis. The timeline for Chromium-based browsers can be found here.
Flash will not be disabled by default from Microsoft Edge (built on EdgeHTML) or Internet Explorer 11 prior to its removal by December of 2020.
Flash will be completely removed from all browsers by December 31, 2020, via Windows Update. Group policies are available for enterprise admins and IT pros to change the Flash behavior prior to that date.
Companies reliant on Flash for development and playback of content are encouraged to remove the dependency on Adobe Flash prior to December 2020.
