    It seems a problem in all versions but I am testing the v10 on a new server I need to check all websites before going live.
    When a user clicks sitepreview they get an 500 error. Running the site on localhost shows me this error:

    Calling LoadLibraryEx on ISAPI filter "C:\Program Files (x86)\Parallels\Plesk\isapi\sitepreview.dll" failed

    Win Server Web 2008 R2 X64
    Fresh install from OS and Plesk.
    Imported the sites from v9.5.2

    Make sure that you have not IIS in 64-bit mode. IIS on Plesk server can not work in 64-bit mode because all libraries in Plesk are 32-bit.

    Igor, thanks again. Got it working.

    Just curious if there is a timeframe for a real 64bit Plesk?

    Wow, this hasn't been fixed in Plesk 10???

    There are several reasons why you want to keep IIS running in 64bit mode on a 64bit server. Namely, to ensure compatibility with other native x64 apps that utilize IIS on the same machine.

    With Plesk 9, I had TONS of problems with SmarterMail, SmarterStats, and Microsoft Team Foundation Server 2010, because these server apps are expecting iis in 64bit mode. Some don't even give you the option to install the 32bit version on a 64bit server! I was left trying to hack Smarter Tools executable files to run in 32bit mode with a tool called CorFlags, and this would reset every time I upgraded to a newer version (which results in unecessary downtime).

    And forget trying to trick TFS 2010 to work with it. I ended up running IIS in 64bit mode and cutting out the sitepreview module, so that all my software would work natively.

    Which brings me to my next point: Is there anything preventing plesk from working properly in IIS native 64bit mode besides the site preview? If there is, you guys need to make a list, and potentially allow the disabling of these features in the admin. If site preview is the only module, then just spend the time to upgrade that single feature!

    What is unbelievable is that you can go release after major release and still not know how much heartache this "hack" causes for your 64 bit clients!

    Starting from 10.4 version, Plesk doesn't switch global switch in IIS Enable32bitAppOnWin64. Now this option enabled on Plesk related Application Pools only. We have removed all global ISAPI filters used by Plesk, so now there should be no conflicts with other applications installed near Plesk.
