Hello

I am trying to install Exchange 2010. Therefore, the installer says that I have to change the IIS to 64bit mode.

I am already running 2 websites on IIS, can I change IIS to 64bit easely without messing up my websites?

How do I do it?

THanks

I don't see how it could. Do you have any 32/64 bit code/threading on these sites?
To be doubly doubly safe you could take a system restore and roll back in anything weird happened

Fortunately I did...

Both websites dont run anymore :-/

What I did was:

cscript %SYSTEMDRIVE%\inetpub\adminscripts\adsutil.vbs SET W3SVC/AppPools/Enable32bitAppOnWin64 0

// Uninstalling 32bit
%SYSTEMROOT%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -u
%SYSTEMROOT%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -u

// Installing 64bit
%SYSTEMROOT%\Microsoft.NET\Framework64\v2.0.50727\aspnet_regiis.exe -i
%SYSTEMROOT%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

What did I do wrong?

Thanks

When you say don't run anymore... what do you get?
Can you create a simple site with either an html or apsx file and serve that up?

What are the sites created in? asp/aspx/php/static html?
Any Db connections?

Have you run an iisreset from the command prompt to be sure iis restareted?

This is the error message:

Fehler beim Aufrufen von "LoadLibraryEx" für den ISAPI-Filter "C:\Parallels\Plesk\isapi\sitepreview.dll". (german)

Means something like "Error while loading "LoadLibraryEx" for the ISAPI-Filter "C:\Parallels\Plesk\isapi\sitepreview.dll"


=> Plesk is installed, is Plesk not compatible with x64?

Ok, its working now.

Plesk has registered a non-64bit-compatible ISAPI Filter for generating Site-Previews. As I dont need this feature, I just removed the SitePreview-DLL as ISAPI-Filter.

Thanks!
