Can't Print to Acrobat 8

Question

My XP apps are now unable to print to Acrobat 8.  It always worked before, but now I get messages saying it is unavailable because Acrobat is not activated.  Yet it IS activated.  In Control Panel, Printers and Faxes shows Acrobat as the primary printer.  In the Acrobat Help menu, under Activation, Activate is grayed out, meaning that it IS activated.  Here's a screenshot of the message I receive.

Answer 1

This error was fixed in Acrobat 8.1. Download the update the update to see if it helps.
If you are already at 8.1 then there are a ton of steps that are associated with trying to fix this issue.
Error "Adobe PDF creation cannot continue because Acrobat is not activated" | Acrobat
Issue
When you try to create a PDF using Adobe PDF Printer or the Convert to Adobe PDF (PDFMaker function) feature from various applications, you receive the following error:
"Adobe PDF creation cannot continue because Acrobat is not activated."
Solution
Note: The information below is based on the Classic version of Windows XP.
Do one or more of the following:
Solution 1: Make Adobe PDF Printer the default printer.
To set up the Adobe PDF printer as the default printer:
Choose Start > Settings > Printers And Faxes (Windows XP) or Start > Settings > Printers (Windows 2000).
Right-click Adobe PDF, and then choose Set As Default.
Solution 2: Move the .tsf data file to the Desktop.
Go to C:\Documents and Settings\All Users\Application Data\FLEXnet.
Right-click on adobe_00080000_tsf.data and choose Copy.
Paste the file to the Desktop or another location where you can easily find it.
Go back to C:\Documents and Settings\All Users\Application Data\FLEXnet and delete the adobe_00080000_tsf.data file .
Restart Acrobat and see if it prompts you to activate the software.
Solution 3:  Move the cache.db file.
The cache.db file could be causing this issue. If the solutions above do not resolve the issue, follow the steps in this solution.
   Navigate to the following folder
On Windows:  C:\Program Files\Common Files\Adobe\Adobe PCD\cache
On Mac OS:  /Library/Application Support/Adobe/Adobe PCD/cache
      2.  Move the following files:
pcd.db
cache.db
caps.db
      3.  Launch Acrobat and you are prompted to reenter the serial number.
Note: Removing these files discards product information and serial numbers from the machine. Reenter this data when launching the product.
Solution 4: End Process on acrotray.exe in the Task Manager
With Acrobat closed perform a CRTL + ALT + Delete on your keyboard.
Click the Task Manager button.
Click on the Processes Tab and highlight acrotray.exe in the list of processes.
Click on the End Process button and click Yes on the Task Manager Warning dialog box.
Try to re-launch Acrobat.
Solution 5: Temporarily disable programs that perform virus scans and repair Acrobat.
Programs that scan can conflict with the activation process. Before you activate your Adobe software, temporarily disable the following programs:
Virus protection software (for example, McAfee, Norton Anti-Virus)
Firewall software (for example, ZoneAlarm, Norton Internet Security Suite)
Software that stores deleted files or removes temporary files from the system (for example, Norton SystemWorks).
For instructions on how to disable or reenable a program, see its documentation. To disable firewall software, contact your system administrator.
Important: Disabling the software firewall can leave your computer vulnerable. Disabling the software does not ensure that all functions of the software are disabled.
Once the software has been disabled, perform a repair of Acrobat:
Choose Start > Settings > Control Panel.
Double-click Add or Remove Programs.
Select the current version of Acrobat and click Change.
Follow the onscreen instructions to repair Acrobat.
Solution 6: Create a local administrator account and then start Acrobat.

Contact network administrators for assistance creating administrative accounts within a domain. If possible, create a new local administrative account using the steps below.
Right-click My Computer and click Manage.
Expand Administrative Tools > Local Users and Groups > Users.
Right -lick Users and select New User.
In the New User dialog box, type Administrator in the Description field. Complete the remaining fields.
Deselect User Must Change Password At Next Login and check Password Never Expires, and then click Close.
Right-click the newly created user and select Properties.
Select the Member Of tab and click Add.
Type Administrators in the Enter The Object Names To Select field, and click OK.
Click OK to close the User Properties window.
Log off the current user and log in to the newly created Administrator account.
Launch Acrobat again and attempt the activation process.

The Administrators group listed below is the default local administrative group in Windows XP, Vista, and Windows 7.
Disclaimer: This procedure involves editing the Windows registry. Adobe doesn't provide support for editing the registry, which contains critical system and application information. Make sure to back up the registry before editing it. For more information about the registry, see the Windows documentation or contact Microsoft.
There are two tasks you can perform before you do these steps to back up your current system and registry:
Create a restore point on your computer by choosing Start > Programs > Accessories > System Tools > System Restore.
Back up your registry immediately after you enter the Registry Editor by choosing File > Export. Give the backup copy of the registry a name and location you can remember.
Windows XP
Choose Start > Run, type regedit in the Open text field of the Run dialog box, and then click OK.
Back up your current registry file:
In the Registry Editor dialog box, choose File > Export.
Type a name for the file and select a location.
For Export Range, select All.
Click Save.
Navigate to this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FLEXnet Licensing Service
Right-click the FLEXnet Licensing Service key and select Permissions.
In the Permissions For FLEXnet Licensing Service dialog box, verify that the Administrators and SYSTEM groups are present. Also make sure that Full Control is selected in the Allow column for both groups.
Click Advanced.
In the Advanced Security Settings dialog box, click the Owner tab. Then select the Administrators group (1), select "Replace owner on subcontainers and objects" (2), click Apply (3), and click the Permissions tab (4).
Note: Select the current administrator account if the Administrators group is unavailable.
In the Permissions tab, select "Replace permission entries on all child objects with entries shown here that apply to child objects" (1) and click OK (2).
Click OK in the Permissions for FLEXnet Licensing Service dialog box. Windows resets the permissions for each child object to correspond with its parent.
Close the Registry Editor.

Click Start, type regedit in the Start Search text field, and press Enter.
Back up your current registry file:
In the Registry Editor dialog box, choose File > Export.
Type a name for the file and select a location.
For Export Range, select All.
Click Save.
Navigate to this key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\FLEXnet Licensing Service
