EPiServer 4 and windows 2008/IIS7



I was reading the page, but I couldn't find anything about windows 2008 or iis7. Is EpiServer 4 supported to run on this kind of setup? Will it work as supposed?

I don't know what the official position is, but it works fine as far as I can tell. Add an application pool that uses classic mode ("like IIS <= version 6"), and set its bitness to 32-bit:

appcmd apppool set / /enable32BitAppOnWin64:true

(You can do it from the IIS7 manager as well with the app pool's advanced settings.)

This last step is to make sure IIS uses a 32-bit worker process, so you don't run into P/Invoke-issues or any other similar problems. Your web site will still get a full 4 GB memory space on x64 (I assume everyone uses x64 today), which usually is more than enough (it's twice the size that you get on x86).

You can then simply create a new website that uses this application pool, and everything should run smoothly.

I hope it helps!

As far as I know, runing EPiServer 4 on windows 2008 with IIS7 is not officially supported.

Will it ever be supported officiallly?

No, you will have to upgrade to a version that supports 2008/IIS7.

You can find the supported plattforms in the Systems Requirement for EPiServer 4.62
