    Hi there,

    I'm trying to get 3CX up and running on a VPS and I'm nearly there!

    Unfortunately, it appears that although the OS is running as 64bit, IIS (version 6) is configured for 32bit only to support the installation of plesk.

    When 3CX installs - it appears it detects that the OS is 64bit and installs the management site assuming this will be the case for IIS? As it's not possible to run both 32bit and 64bit application pools in IIS6 (though I've read this is possible in IIS7) - is it possible to force 3CX to use a 32 bit install?

    I've also tried cassini as a backup approach, but have hit problems with this too and would prefer to stick with IIS?

    Can anyone suggest a solution?

    Hi there

    Installing under IIS in 32-bit with ths OS in 64-bit is currently not working.

    At this time, the only option available to you to install 3CX is to use Cassini as the web server. The latest 7.1 available for download has a number of fixes implemented which resolve some issues previously visible with Cassini.

    Hi Kevin,

    OK thanks..

    I think I must just be unlucky, as when I install the IIS version - it installs without errors, (until you come to log into the management page).

    However when I install with Cassini - it gets to the last step of the wizard and fails to start the services :

    Looking in Event viewer there are some ASP.NET errors:

    Any ideas what I'm doing wronng? Is this another 32/64bit problem?

    If I go to the mnagement page now I get an error : Could not load file or assembly '3cxpscomcpp2

    Yes this is exactly why it will not work. The installation will work because the installation has nothing to do with the loading of IIS.

    Since the machine is 64 bit, it will install 64 bit DLL's. That is because it assumes that the 64 bit machine has the standard IIS that came with it - ie running 64 bit.

    When you open the site IIS is running in 32 bit mode and loading the 64bit dll will fail. This is because if IIS is running in 32 bit mode, it expects the dlls to be in 32 bit.

    This is why it will try to load them on a 32 bit environment and it will fail.

    You have 2 options -
    1) Install Cassini,
    2) Install on IIS on another machine that runs IIS in native mode. A virtual machine for example.

    What are the problems that you had with Cassini?

    What version are you using?

    If the services are not starting this is a separate issue. I think you have some traces left from a previous installation.

    To solve this you have to UNinstall, Run the installation checker available from
    http://wiki.3cx.com/Home/downloads (installation checker tool)
    Follow the FAQ's and remove the traces left.
    Restart the machine
    After this install latest version 7.1 and select Cassini.

    Thanks and regards
