I find that in my Cloud Web Security portal that version 1145 is the most recent version available (1.4.7.6.1145) and the Release Notes do not mention explicitly supporting Windows 8 or 8.1 (but there is a mention that "…endpoint does not support Windows 8 Metro apps…") Which seems to indicate that there may be some level of support on Windows 8.
Page 3 of 1145 Release notes do explicitly note:
Supported operating systems
Windows XP with Service Pack 2 or higher (32-bit and 64-bit)
Windows Vista with Service Pack 1 or higher (32-bit and 64-bit)
Windows 7 (32-bit and 64-bit)
My question is are there folks out there with 8 or more specifically 8.1 running with Web endpoint?
thanks
