Photoshop Elements: Use LARGEADDRESSAWARE flag to allow up to 4GB of RAM even though it's not a 64bit application

Dear PSE developers,

since the new PSE 10 is still not a 64bit application, I would like to ask if you can't at least set the LARGEADDRESSAWARE flag to allow PSE use up to 4GB of RAM even though it's not a 64bit application.
That way, PSE won't run out of memory so soon and can finally use at least twice as much RAM on systems that have 4GB or more installed. Opposed to adapting PSE to 64bit this task should not require a lot of effort.

Cheers,

Timo

I hardy think this would be an easy task, if it's even possible or the adobe engineers would have already done that for photoshop.

I think a better request would be to suggest a 64 bit version of photoshop elements.

Photoshop has had that flag set for many years.

Just because Adobe developers didn't do it yet, it doesn't mean it's harder to do than adapting a sotware to 64bit. There are users out there who even do that themselves with tools like this: http://www.ntcore.com/4gb_patch.php
They can now use up to ~3.2GB (as opposed to the standard 1.5-1.6GB maximum) on Windows 64bit systems and don't have any problems to report.
Of course it would be much nicer to have an official release that has been thoroughly tested, since I don't like applying third-party patches to software.

The one thing developers have to make sure when setting the largeadressaware flag is that no pointer assumptions are made by the application, such as assuming that the high-bit is never set in a 32-bit pointer. But that shouldn't be such a big deal.

Oh, I didn't know that. I'm still using PSE7 and the information that PSE9 still doesnt use more than 2GB was based on other peoples complaints in forums. Well then I guess this is obsolete.
