Troubleshooting & help
Download Acrobat directly from the Acrobat website. Sign in with your Adobe ID and password to complete the download. For installation instructions, see Download and install an Adobe Acrobat DC subscription.
You can install Acrobat on up to two computers. If you want to install it on a third computer, sign out on one of your previous machines. Choose Help > Sign In/Sign Out. To learn more, see Install and use Acrobat DC on a new computer.
Many web browsers, such as Chrome, Firefox, and Safari, now use their own PDF viewer instead of the Adobe PDF plug-in. For best results, configure your browser to use the Adobe PDF plug-in to open online PDF files.
Document Cloud includes Acrobat and Adobe Sign, along with web and mobile apps. With the Acrobat Reader mobile app, you can create, edit, comment, and sign PDFs directly on your phone or tablet. And with Document Cloud web apps, you can work with PDFs and manage e-signatures from a browser on any computer. For more details, see Adobe Document Cloud FAQs.
