ATTENTION : All the components of the v2.2 WampServer stack have been compiled with VC9 version of Microsoft compiler.
Earlier versions of Wampserver have been made with VC6 version of Microsoft compiler.
So, You can't mix components of 2.2 stack with previous version of Wampserver Stack components. If you do it you will get an instable Wampserver.
I got version 2 and want to update to version 2.2. I assume the version 2 has been compiled differently, so updateing would make my wamp unstable.
Update instructions anyone? There are no update instructions in the FAQs.
