64-bit Vista is listed as a supported platform in the he latest Flash Player tech specs:
- 32- and 64-bit: Microsoft® Windows® XP, Windows Vista®, Windows 7, Windows 8.x
The latest version of Flash Player for all supported Windows (and Mac) platforms is 220.127.116.11. The table on this page, http://www.adobe.com/software/flash/about/, is regularly updated with the latest supported versions.
The System Requirements for Adobe Flash Player 18 on Adobe Flash Player Install for all versions does not state Windows Vista 64-Bit as it just states Windows Vista (32 bit).
I tried installing Adobe Flash Player 18 for IE - Active X and it does not work for Windows Vista 64-Bit, however, my Chrome Browser has Adobe Flash Player 18 and it does work for Windows Vista 64-Bit.
While 64-bit Vista is not listed on there, the latest version of Flash Player, 18.104.22.168, will still install on it.
What does 'does not work mean'? Does it install correctly, but Flash content doesn't display? Are you using the 32-bit or 64-bit IE browser?
I downloaded Flash again for IE - Active X using my IE 32 Bit which I used previously but this time it installed OK.
It must have been a "glitch"
