First of all, no, ColdFusion is not yet supported on 64-bit Windows. And I don’t have a date for when it will be.
But, ColdFusion MX 7 can indeed run on 64-bit Windows (I have been doing so for a long time now). The trickier part is getting ColdFusion to talk to 64-bit IIS 6 (which by default only talks to 64-bit apps and connectors).
A Microsoft document entitled Configuring IIS to Run 32-bit Applications on 64-bit Windows (IIS 6.0) explains that Windows Server 2003, SP1 enables IIS 6 to run 32-bit Web applications on 64-bit Windows using WOW64 (the Windows-32-on-Windows-64 compatibility layer), and provides the instructions needed to enable this functionality.

Ben,
Thanks for the post, it’s good to know that this is not a dead end option until CF supports 64-bit.. I had tried this about a month ago and was able to install CF on the server (win 2k3 64-bit)… however the next stumbling block was the JDBC.. we couldn’t get a datasource to run (MS SQL Server 2k) .. in the CF Administrator.. would you or anyone have any documentation on this issue?
Once again.. thanks..
Cheers.. -
Given the choice of installing 32bit or 64bit Windows 2003 to run purely as a IIS/CF web server, which one should I choose? There must be a performance hit if CF uses the WOW64 compatability layer? Is going for 32bit the best choice?
-
But Sun has a 64bit JVM for 64-bit Windows, right? What else would you need to run CF on 64bit? The 2GB per process limitation of 32bit Windows can be a real problem for some users, esp with those using lots of memory variables, query caching etc on sites with many visitors.
If you run multiple instances of CF on 64bit Windows, would each instance be able to get 2GB? -
cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 “true†will not work, you have to pass true as a bool, not a string.

Have you been able to get RDS to work with CF on a 64-bit server? We have not. When we try to get a connection using HomeSite, we get an alert popup box titled "Remote Server Operation Failu…" that says "HTTP Error :400".
CF 7.0.2 is running on Windows 2003 Server x64.
Thanks. -bg -
What about CF v5? we’ve got a new x64 server but still want to use CF v5………is there going to be any help for us???
-
Christopher, it may work, but you’re on your own. CF5 is over 7 years old and is no longer a supported product, we are not going to be adding functionality to that release.

Thanks for the tip! It has been very helpful in getting my CF 7 server running on a hosted Win2k3 x64 server

When you install it on Windows 2003 64-bit OS? Did you use the standard installer or have to go some other route? Also, does the installer install the 32 bit JVM that seems to be required?
-
Hmm, CF 7 was working, then I installed the 7.02 upgrade and now it’s broke again.

I am trying to install coldfusion 8 on ms Server 2003 R2 and what I get is a 401.3 error : Unauthorized Due to ACL on Resource for ALL the website on the server. When I remove coldfusion, all is back to normal. I tried the cscript.exe adsutil.vbs set W3SVC/AppPools/Enable32BitAppOnWin64 true trick. It did not help at all. Any idea?

What about cf8 on the new IIS 7 and server 2008 64bit?
-
mgwalk, it’s coming soon, see this thread: http://www.forta.com/blog/index.cfm/2008/3/2/Planned-Platforms-For-64bit-ColdFusion

In fact, there was 2 IUSR and IWAM accounts on the server making IIS and Coldfusion not understanding which one to take. According what I saw on IIS 7 inventing a group having the anonymous internet accounts, they have solved this issue.
By the way, the solution of my situation was just to delete the account not having the computer name in it.
