...ordinary owner/user who is interested in updating to reduce vulnerabilities?
Win98/Win98SE/WinME - v1.5.0_11 (If you attempt to install v1.6.0, you get message "Warning: This is not a supported Operating System")
WinXP - v1.6.0 ...
Win2k - ??? (Dunno. 'Don't have a system with that platform available to test it.)
Above are -all- IMHO, since "they work for me". -YMMV- "...All information on this website is provided "AS IS" without warranty of any kind. We disclaim any responsibility for the use of services and/or tools you may link to and/or use from this website. And, yes, we also feel the very "need" for disclaimers is an incredibly sad statement about our society..." Blah, blah, blah...
In all this, I have NOT come across -any- recommendation for reference from an established large, medium, or small organization, business, or institution, and I'll probably end up in one of the latter if this confusion continues.
