History
Word Viewer 6.0 was 16-bit and corresponded to Word 6.0. Word Viewer 7.0 and 7.1 was 32-bit and corresponded to Word 95. Word Viewer 7.1 would execute WordBasic macros without warning. The typical macro virus would not spread, but it could still execute (including any malicious code).

Word Viewer 97 was released with Word 97.  It was available for Windows in 32-bit versions. It can display Word documents in Internet Explorer 3.x and later.

Word Viewer 2003 was released on 15 December 2004. This includes many security enhancements over Word Viewer 97, and was the first version of Word Viewer to receive security updates.

Word Viewer 2003 Service Pack 3 was released on 26 September 2007 with Office 2003 SP3. Microsoft continued to provide security updates until February 2019 (mostly because POSReady 2009 shipped with it). 

Development of the product has stopped ever since. In the meantime, Microsoft has made other ways of reading Office documents available, either through Word Online as well as WordPad (a native component of Windows) in Windows 7 and later, which can create, view or edit Office Open XML documents (.docx) alongside Rich Text Format (.rtf) and text files (.txt).

No versions for any other operating system besides Windows were ever released.
