Update Information

What's included in the ColdFusion 8 Update 1?

ColdFusion 8 Update 1 provides full 64-bit support for several new platforms including versions of Windows, Mac OS X, and Linux, in addition to Solaris (which was added with the initial ColdFusion 8 release). We have also improved functionality in several areas including AJAX functions, CFPDF, and CFIMAGE. We have also updated several software libraries.

Full details on these and other enhancements/fixes are available in the Update Release Notes.

Where can I get the ColdFusion 8 update?

If you purchase ColdFusion as a download from our Online Store, the update will already be included in your product installer. You will see the product version as ColdFusion 8.0.1.

Boxed Product;If you purchased ColdFusion 8 as a boxed product, you can do one of the following to ensure you have the update:

  • Download and install a trial version of the product and then unlock the full licensed version by entering your serial number either during installation or from the ColdFusion Administrator.
  • Install ColdFusion 8 from the CD and then download and apply the 8.0.1 update.

Trial Downloads;The update is already included in full trial download installers. You will see the product version as ColdFusion 8.0.1.

Can I download a version of ColdFusion 8 that already includes the update?

Full Trial and Developer editions of ColdFusion downloaded from Adobe.com already include the update. You will see the product version as ColdFusion 8.0.1.

Does ColdFusion have 64-bit support?

As of ColdFusion 8 Update 1, ColdFusion Enterprise and Developer editions can run as 64-bit applications on the 64-bit versions of the following operating systems:

  • Windows XP, 2003, Vista and 2008
  • Macintosh OS X 10.5 (for Intel-based Macs)*
  • Red Hat Enterprise Linux5.0
  • SUSE Linux 10.1 and above (glibc-2.5-25 is required)
  • Solaris 9 or 10 (Also supported in the initial ColdFusion 8 release)

* Note that Mac PPC 64-bit OS is not supported.

For detailed information about supported platforms, see the ColdFusion System Requirements. Note that ColdFusion 32-bit cannot be upgraded to ColdFusion 64-bit using the Update. ColdFusion should be uninstalled and installed again using the 64-bit full installer available on the ColdFusion 8 Trials page.

Does ColdFusion Standard have 64-bit support?

As of ColdFusion 8 Update 1, the Standard Edition can run as a 32-bit application on all supported 64-bit platforms in addition to 32-bit platforms. For detailed information about supported platforms, see the ColdFusion System Requirements.

What are the benefits of running ColdFusion as a 64-bit application?

64-bit computer architectures can provide higher performance than 32-bit architectures by handling more information in the same clock cycle. In addition to performance, the size of the memory space an application can use is significantly larger. 32-bit computing architectures can address approximately 4 GigaBytes of memory, 64-bit computing architectures can address 16 ExaBytes of memory. For practical purposes today, this is an 'unlimited' amount of memory which allows memory intensive operations such as reading in large files or returning large datasets, to operate more efficiently. Applications which require more memory and execute more computations will perform better on 64-bit systems than on 32-bit systems.

What are the limitations of running ColdFusion as a 64-bit application?

Although ColdFusion 8 Update 1 has complete 64-bit support, there are a few limitations.

  • ColdFusion COM Interoperability is not supported.
  • ColdFusion cannot access MS Access databases on a 64-bit system.
  • ColdFusion Delphi Interoperability is not supported.
  • DataDirect Drivers, Verity Search functionality, and ColdFusion .Net integration still run as 32-bit applications.

Which JDK version, application servers, and web servers are supported on my 64-bit Operating System?

For detailed information about supported platforms, see the ColdFusion System Requirements.

Can I run ColdFusion 64-bit on Apache 32-bit Web server?

Yes. Please read the ColdFusion 8 Update Install Guide for details.

I have ColdFusion 8 installed today on a 64-bit Operating System. Can I just run the Update to upgrade it to ColdFusion 64-bit?

No. You will need to completely uninstall ColdFusion and use the full ColdFusion 8.0.1 installer. Please read the ColdFusion 8 Update Install Guide for details.

On Mac OS X 10.5, I see 2 directories: /etc/httpd and /etc/apache2. Which is the correct directory to use for configuring Apache connector?

You may see these 2 directories in Mac 10.5 if you have upgraded from Mac 10.4. /etc/apache2 is the correct directory. Please read the ColdFusion 8 Update Install Guide for details.

On Windows Vista 64-bit, after installing ColdFusion, ".cfm" files cannot be accessed. It throws a 404.3 error code. What may be the issue?

In some cases you may need to manually enable IIS 6 compatibility options. To enable this, navigate to Control Panel > Programs > Programs and Features > Turn Windows Feature On or Off > Internet Information Services > Web Management Tools > IIS6 Management Compatibility and then enable all options. Please read the "Configuring the ColdFusion 64-bit Connector" section of the ColdFusion 8 Update Install Guide for details.

".cfm" files cannot be accessed after configuring the apache connector using wsconfig. What may be the issue?

This may happen if the Connector is not configured properly.

One possible reason is that ColdFusion 64-bit could be configured to use the Apache 32-bit Web Server. By default, ColdFusion 64-bit loads the 64-bit connector module unless it is specifically mentioned in wsconfig to load the 32-bit connector module. If you use the wsconfig user interface to configure 32-bit Apache with 64-bit ColdFusion, you must enable the "configure 32 bit web server" option. If you use the command line tool, you must add the ws32 option to the command. This will tell ColdFusion to provide the 32-bit connector module to Apache 32-bit WS.

This may also happen if ColdFusion 32-bit is configured to use the Apache 64-bit Web Server. This configuration is not supported.

Please read the "Configuring the ColdFusion 64-bit Connector" section of the ColdFusion 8 Update Install Guide for details.

How can I switch the mode that IIS is running in?

To switch IIS from running in 64-bit mode to 32-bit mode, execute the following command from %systemdrive%\Inetpub\AdminScripts directory:

cscript.exeadsutil.vbssetW3SVC/AppPools/Enable32BitAppOnWin64true

To switch IIS from running in 32-bit mode to 64-bit mode, execute the following command from %systemdrive%\Inetpub\AdminScripts directory:

cscript.exeadsutil.vbssetW3SVC/AppPools/Enable32BitAppOnWin64false

On Mac OS X 10.5, how can I switch Apache running in 64-bit to 32-bit mode?

To switch Apache from running in 64-bit to 32-bit on Mac OS X 10.5, do the following:

  1. Go to /usr/sbin and make a backup of httpd (for example, httpd.back).
  2. Run the following command from the terminal:



    sudo lipo httpd -thin i386 -output httpd



  3. To confirm the resulting http architecture, from /usr/sbin, run the following command:



    file httpd



  4. The file command should give httpd:Mach-O executable i386.
  5. Restart Apache by running the following command:



    sudo ./apachectl restart



  6. The conf file (httpd.conf) location remains the same (/etc/apache2).

To make Apache run in 64-bit mode again, replace the current version of httpd with the backup httpd file you saved in step 1, and then restart Apache.
