Adobe Acrobat 8.1 is an update to Adobe Acrobat 8, which was released in November 2006. The software is used to create, view, manipulate, manage and print PDF files.
Adobe Acrobat 8.1 comes with a variety of features that include support for Windows XP 64-bit edition, Windows 2003 64-bit edition, Windows Vista 32-bit and 64-bit editions, Microsoft Office 2007, and fixes a number of issues that were discovered after the release of Adobe Acrobat 8.0. Some of these bugs included 100 percent CPU usage after running the software updater, crashes after double-clicking a signature, SnippetRunner memory corruption and bookmarks disappearing from the bookmark pane after clicking a link. Users running 64-bit operating systems may experience issues using the PDF printer, but Microsoft has issued a hot fix that is available on its support website. Adobe supports the PDF printer with this hot fix installed.
With the discontinuation of support for Adobe Acrobat 8.0 in November 2011, users seeking the most current version of the software should consider upgrading to Adobe Acrobat 11, which has continued support until Oct. 15, 2017, and includes features that allow users to export PDF files to Microsoft PowerPoint as well as allow for touch input.
