I installed this on IIS and received the following error when I try to enable it:
vB Optimise: You have selected a cache method that vB Optimise has detected you cannot use, this may be because the extension required is either not installed or configured correctly on your server. Please contact your system administrator or hosting provider for more information.
I am using Wincache and according to phpinfo it is enabled:
wincache
Opcode cache enabled
File cache enabled
Version 1.0.1325.0

Any ideas what I might have missed?
