Go Lightroom

You may be wondering how to run Lightroom 2 as a 64-bit application on Windows XP x64.

Lightroom will not install as a 64-bit application on Windows XP by default because it’s not an officially supported platform for 64-bit version. Lightroom is officially supported only on Vista x64.

But when you run the Lightroom installer and choose to “Open the Specified Folder” in the Files are Ready dialog (Be sure to uncheck the option to “Launch the Adobe Photoshop Lightroom 2.0 Installer”)  you’ll see an Adobe Photoshop Lightroom directory that contains “setup32″ and “setup64″ executables.

Once again, running Lightroom 2 as a 64-bit application on Windows XP x64 is not a supported configuration.

Why all the excitement about a 64-bit version of Lightroom? First of all, you should use 64-bit version of operation system if you have 4GB or more of RAM. (Or at least planning to add enough RAM in nearest future). 64-bit capable operating systems and applications can take advantage of more memory than 32-bit systems.

If you have a 64-bit environment with 4GB or more of RAM you’re most likely to see great improvement in the responsiveness of the Develop module where Lightroom is loading large amounts of information into memory.
