I’m trying to deploy a site to a 64bit OS. I’m deploying to IIS6.

I’m trying to deploy a site to a 64bit OS. I’m deploying to IIS6. The site was developed on a 32bit server. The site deployed correctly however it’s trying to access a COM component and that is failing.

I believe the error is occurring because the COM component is a 64bit version on the 64bit OS. And IIS6 is running in 32bit mode on the 64bit server.

I’d like to confirm this but I can’t seem to find a definitive way to check if IIS6 is in 32bit mode or 64bit mode.

Would someone know the best way to check if IIS6 is in 64bit or 32bit mode?

EDIT: I’m using IIS6

    which version of IIS? to check it manually just click the application pool, in properties or advanced properties

    if you need to check it programatically you can do it through WMI:

    /LM/W3SVC namespace on the

    IIsWebService class

    Enable32BitAppOnWin64 property
