Can't open LR4, not supported on this type of Mac

I just successfully installed LR4, however, it won't open the application because it says it is not supported on this type of Mac.  I have a Intel MacBook Pro, OS 10.6.8, with 2 GB RAM, and enough HD space to load and run.  I already have LR3 installed and it's up to date.  What gives?

    Which MacBook Pro model exactly? How was the operating system installed? Straight off the DVD or by patching an older version incrementally? Anything else we may need to know?

    Mmh, sounds odd. Any chance you could go fishing for install logs? This might reveal some more details.

    The Intel Core Duo processor is a 32-bit processor.  Per the system requirements - http://www.adobe.com/products/photoshop-lightroom/tech-specs.html you need a 64-bit processor.  The Intel Core 2 Duo is the 64-bit version.

    Arnold you are certainly welcome to return the product.  You can find the process for submitting a refund request at Return, change Adobe orders | North America - http://helpx.adobe.com/x-productkb/policy-pricing/return-change-orders -north-america.html.

     

    I have a similar issue with my personal MacBook Pro as it is using an Intel Core 2 Duo at 2.33 ghz.  While it can run 64-bit applications I am not able to run Snow Leopard in 64-bit mode without doing unsupported, by Apple, modifications to the OS.

     

    You might also find this document useful 64-bit OS and Adobe applications - http://helpx.adobe.com/creative-suite/kb/64-bit-os-applications.html and it might help explain why we are transitioning many of our applications to 64-bit.  It is especially useful for applications which can make use of a lot of memory such as image editing and video editing/processing applications.
