ColdFusion 8 will run on 64-bit Windows with a 64-bit JRE, but only if you pay for Enterprise. While the ColdFusion 8 32-bit installer will run on Windows 64, the IIS connector fails miserably. I worked around this problem by using the IIS Connector from the 64-bit installation with a ColdFusion instance running with its 32-bit installation.
Fist, install the "normal" ColdFusion 32-bit version, but select "Built-in web server (Development use only)" on the Configure Web Servers/Websites screen:
Next, install the 64-bit version of ColdFusion, with the following options:
- On the "Install Type" screen, choose "Developer Edition":
- On the "Subcomponent Installation" screen, install no complementary services.
- On the Installation Directory screen, choose "ColdFusion64" (or any dir other than where you installed 32-bit ColdFusion)
- On the Configure Web Servers/Websites screen, select "All IIS websites" (which is the default).
At this point, you may be able to hit http://127.0.0.1/CFIDE/administrator/index.cfm to configure your ColdFusion instance. If not, check the following items:
- Run regedt32, and verify that the ImagePath attribute in the ColdFusion 8 Application Server service (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ColdFusion 8 Application Server) is set to "C:\ColdFusion8\runtime\bin\jrunsvc.exe"
- Ensure that the "ColdFusion 8 Application Server" service is started. If there's a problem, open a command prompt, CD \Coldfusion8\bin, and run CFSTART. Look for errors.
- Open C:\ColdFusion8\runtime\servers\coldfusion\SERVER-INF\jrun.xml. Search for "JRunProxyService"; make sure the "deactivated" attribute is "false" and that the "port" attribute is "51011". (If you need to fix either of these, ColdFusion must be restarted.)
- Make sure the 64-bit connector is also pointing to 51011: in the file C:\ColdFusion64\runtime\lib\wsconfig\1\jrun_iis6_wildcard.ini file, the "bootstrap" entry should be set to "bootstrap=127.0.0.1:51011". If you need to fix this, IIS must be restarted.
Note that you'll never actually start the 64-bit instance, but it must be left in place because you're using its web server connector.
As a side note-- if you try to start ColdFusion 8 Professional in a 64-bit JVM (with either installation type), ColdFusion will revert to a "Developer" license.
Update: If the above doesn't work for you, see Jason Holden's Post on the same subject.
