Yea, .NET can be a bit trying on 64-bit. ;) I would definitely poke about Aaron Stebner's blog: <http://blogs.msdn.com/astebner/>. It may be that .NET 1.1 is required for full functionality also. There is no problem running 1.1 and 2.0 side by side but keep in mind that 1.1 is 32-bit only and as such runs under WoW64. During installation of 1.1 on 64-bit platform I would suggest temporarily disabling data execution prevention. <http://blogs.msdn.com/astebner/archive/2005/07/27/444085.aspx> You may also run into a mscoree.dll issue. See here for details: <http://blogs.msdn.com/astebner/archive/2007/06/12/3260076.aspx> You should have mscoree.dll version 2.0.50727.1433 (REDBITS.050727-1400) in %windir%\SysWOW64\ and while you're at it verify these bits here (slightly different than 32-bit system's values at Aaron's): <copy below> Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework] "InstallRoot"="c:\\WINDOWS\\Microsoft.NET\\Framework64\\" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Policy] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Policy\Upgrades] "2.0.50727"="1.0.0-2.0.50727" "1.1.4322"="1.0.3705-1.1.4322" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Policy\v1.1] "4322"="3706-4322" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\Policy\v2.0] "50727"="50727-50727" <copy above> .NET 3.0 is more or less extensions to 2.0, and 3.5 is further extensions to 2.0 SP1 and 3.0 SP1. They're both quite new so I really doubt they're needed for OWA, but once you get 1.1 and 2.0 completely sorted it should be painless to get those two installed for completeness sake. ~JasonG -- ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
