|Version of Internet Explorer|
Internet Explorer 5 was released in 1999 and was included with Windows 98 Second Edition, as well as Windows 2000 which included a minor 5.01 bug fix update. It was also available for Windows 3.1x, Windows NT 3.51, Windows NT 4.0, Windows 95 and Windows 98. Users of Windows NT 3.51 must use the 16-bit version, which was the last 16-bit version of Internet Explorer and thus also the last one to work on Windows 3.1.
Initially planned to be released in July 1998, it was delayed until March 1999 due to Y2K issues. It was released in tandem with Internet Explorer 4.01 SP2.
A version of IE 5 was ported to Solaris and HP-UX through the use of MainWin's xDe environment and uses the Trident engine. IE for Mac OS uses a different engine called Tasman which is also used in Office:mac, Entourage, and MSN for Mac OS X.
An updated version, 5.01 was released at the end of 1999 and is pre-installed in Windows 2000. However, it still identifies itself as 5.00. The difference with 5.00 is the image used in the About box and the removal of Microsoft Wallet.
