Unable to open a PDF document using Adobe Reader X

Asked By 0 points N/A Posted on -

I am trying to open a PDF document with Adobe Reader X, but I got the error message: “Before proceeding, you must launch Adobe Acrobat and accept the end User License Agreement.” Opening an adobe file is well and good though. Please help me on what I should do.

This is because of the registry key leftover in your system. Even though you installed newer version of adobe X, you still have the older registry key values in your system. If you can uninstall the older version completely, and install the new fresh version, that should fix the issue. However, if you do not want to do that process, you can do some registry tricks.

Start > Run > Regedit

go to HKEY_LOCAL_MACHINESOFTWAREAdobeAdobe acrobat10.0Adobe viewer.

Simply create the key if the full path doesn't exist.

Now create a new DWORD entry EULAAcceptedForBrowser and set the value to 1.

This should fix the issues with the end user agreement.

Hi Alffie,


I think you are using an old version of Adobe Reader and Adobe Acrobat on your computer. I suggest you to update all your adobe softwares to be able to support PDF documents because older versions may not be compatible winh the Operatin System that you are using now. Also try the following steps to fix your problem:

  • Go to Reader X
  • Under Edit, go to new preference
  • Choose preference
  • Go to general category. It is called select default pdf handler
  • This will allow you to choose the PDF application that you are going to use to open or view PDF documents in the web browser

I hope that this helps you solve your issue.

Hi Alffie

This is a bug in Adobe Reader X. Strangely this error happens when you have the letters "CR" in either the filename or the file path.

To get around the problem rename the file or move it into another directory with no "CR" in it. This seems stupid and will be a waste of time. Then try the following.

  • Open the file from Adobe Reader X  by clicking Open under file menu.
  • In the Adobe Reader X go to the Edit menu and click preferences. In the general category click on Enable Protected mode on startup. Hope this resolves the issue.

It appears the program wants you to accept the EULA again or the End-User License Agreement. This EULA is usually required to be accepted during the installation or at the start of the installation. It is normally no longer asked after installing the software. If you are being prompted again for the EULA, uninstall and reinstall the program.

Download the free version of Revo Uninstaller and install. Once installed, start Revo then select Adobe Reader among the applications and click “Uninstall.” Follow the normal uninstall process. When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer.

When it is finished, exit Revo then install Adobe Reader back. If this doesn’t work, update to Adobe Reader DC. Download Adobe Acrobat Reader DC. It supports Windows 7 Service Pack 1, Windows 8.x, and Windows 10 including Windows Server 2008 R2, Windows Server 2012 (64-bit only), and Windows Server 2012 R2 (64-bit only).

It requires 1.5 GHz or faster processor, 1 GB RAM, 380 MB free space, and 1024 x 768 minimum screen resolution. Supported browsers include Microsoft Internet Explorer 11 and Mozilla Firefox ESR edition. Please read and check other optional downloads before hitting the “Install now” button to download the installer to avoid downloading other bundled software.

Alternatively, you can use Foxit PDF Reader. It supports Windows 7, Windows 8.x, and Windows 10. It is compatible with Microsoft Office 2007 and higher.
