Adobe Acrobat Pro allows you to create, edit and convert PDF files into Microsoft Office format. As part of the setup process, you must accept Adobe's end user license agreement. The installer may occasionally fail to complete the process correctly and the program will not save your acceptance of the EULA. This will prevent you from opening the software in the future. There are several known solutions that may correct your problem. If none of the simpler solutions fix the issue, you may have to manually edit your Windows registry.
Types of Problems
You may encounter several different issues when attempting to click the "Accept" button for the EULA. In some cases, the "Accept" and "Decline" buttons may be invisible or distorted. Another known problem causes the buttons to appear initially, but then vanish when you click anywhere on the screen except on one of the buttons. Alternatively, you may be able to see the buttons, but be unable to click them because the cursor changes to a text entry selector instead of a pointer whenever you mouse over them.
If you can see the "Accept" button on your screen, you may be able to select it by using the "Tab" key. Pressing "Tab" shifts the screen focus to the next item, such as a text box, link or button. Once you reach the "Accept" button, press "Enter" to select it. If the buttons are distorted or not visible within the perimeter of the screen, change your display resolution to 1024 by 768 pixels or higher.
Running the Program as an Administrator
Logging in as the workstation's administrator to reinstall the program may help you get past the EULA acceptance problem. You can also right-click on the Acrobat icon and select "Run as Administrator" to run the program as an administrator. You must enter the administrator password to log in before the program will start.
Editing the Windows Registry for 32-bit Systems
Close Acrobat and back up your registry before making any changes. Click the "Start" button and select "Run." Type "regedit" in the text box and press "Enter" to open the registry editor. If you have a 32-bit computer, look for an item titled HKEY_LOCAL_MACHINE\SOFTWARE\Adobe\AdobeAcrobat\product_version\AdobeViewer. Open the "Current Version" listed in the registry editor and look for the AdobeViewer key. If you do not see this item, right-click on "Current Version" and select "New," then "Key" to create a new key. Title the new key "AdobeViewer" and click "OK" to save it.
Editing the Windows Registry for 64-bit Systems
On 64-bit systems, such as Windows 8, the folder will be titled HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\<version>\AdobeViewer. After opening this item, right-click the "EULA" item listed in the right pane of the editor screen. Set the value to "1" and click "OK" to save your changes. If you do not see an item titled "EULA," right-click the "AdobeViewer" folder and choose "New" and "DWORD Value." Name your new item "EULA" and click "OK" to save it. Right-click on your newly created "EULA" item and change the value to "1" to manually force acceptance of Adobe's EULA.
