I've installed 5.3.4 Windows binary (VC9 x86 Thread Safe) on my WampServer version using these instructions, and everything seems to work fine so far with XOOPS 2.5.0.

Thanks Mamba!

Very necessary information (including the link on PAMPSERVER)

Somebody tested it with X3?

With XOOPS 2.5.0 is work fine!

Very simple and clear instruction "Install PHP 5.3.x on WAMP" is herehttp://markushedlund.com/dev-tech/install-php-5.3.3-on-wamp

Pampserver is better because it offers 64-bit version.
