How to launch Photoshop 64 bits from DPP : the solution

Some people who have installed photoshop 32bits and 64bits on the same machine are complaining because when using the 'Transfer to Photoshop command" of DPP it launches the 32 bits version of photoshop instead of the 64 bits. If you want the 64 bits version to be launched, the solution is here : http://digitol.free.fr​/forum/viewtopic.php?f​=2&t=65

Cool. Good tip!

Boy I hate playing in the registry but after a couple of Rolaids I did it and it works great!

My one comment to others though is to make sure you set your paths correctly and don't just type in the path that is in the article because my path was slightly different. The article suggests entering a path of C:\Program Files\Adobe\Adobe Photoshop CS5.1 (64 Bit)\ in the 12.0 branch but on my PC the path was: C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\ (slightly different but it is different). The same goes for the second path of C:\Program Files\Adobe\Adobe Photoshop CS5.1 (64 Bit)\Plug-ins\ but again, my path was: C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Plug-ins.

Anyway, Thank You for the link!

It didnt work for me and my existing paths were there but they read as: C:\Program Files(x86)\Adobe\Adobe Photoshop CS5.1\ for both paths it has the x86. It opens but stil in 32bit. I would love for it to work so I can reinstall CS5 without 32bit to save the space on my SSD.

I could be wrong but the C:\Program Files (x86)\xxx directory is for 32 bit applications (your in the wrong directory). You should have a C:\Program Files directory...that is where you need to point to access CS5 64 bit...

I looked in the exact place those instruction said to look for and that is the only directory that is in there. I am going to uninstall CS5 and reinstall just 64bit and then try this step.

Technically x86 simply refers to a family of processors and the instruction set they all use. It doesn't actually say anything specific about data sizes.
x86 started out as a 16-bit instruction set for 16-bit processors (the 8086 and 8088 processors), then was extended to a 32-bit instruction set for 32-bit processors (80386 and 80486), and now has been extended to a 64-bit instruction set for 64-bit processors. It used to be written as 80x86 to reflect the changing value in the middle of the chip model numbers, but somewhere along the line the 80 in the front was dropped, leaving just x86.
Blame the Pentium and it's offspring for changing the way in which processors were named and marketed, although all newer processors using Intel's x86 instruction set are still referred to as x86, i386, or i686 compatible (which means they all use extensions of the original 8086 instruction set).
x64 is really the odd man out here. The first name for the 64-bit extension to the x86 set was called x86-64. It was later named to AMD64 (because AMD were the ones to come up with the 64-bit extension originally). Intel licensed the 64-bit instruction set and named their version EM64T. Both instruction sets and the processors that use them are all still considered x86.

True but my reference to x86 has to do with the files structure associated with 64 bit Windows and not processors. I found a good page explaining what I am referring to:

http://helpdeskgeek.co​m …wo-program-files-folders/

So, I still stand by my belief that HDR Fan is either in the wrong directory or is not running 64 bit Windows. My files structure is exactly like the above article suggests it should...???

No I am running 64bit windows I installed it myself as well as built my PC. The x86 is 64bit. I have 32 bit win 7 on my office and it has the regular Program files folder only where as my home has both the x86 Program files folder and regualr non x86 folder in the :c drive. I thnk the directory is weird because I installed 32 bit after 64 bit and not at the same time so it is defaulting to 32bit for some reason now. I have 64 bit win 7 and Adobe installed. I am 100% certain of this. the instruction that were written for this work around are just not taking into consideration that windows installs are like snow flakes...no two are ever alike.lol


I am just going to do an uninstall reinstall of just 64bit CS5.

The x86 is 64bit.

On a 64-bit system:
The C:\Program Files (x86) is 32-bit.
The 64-bit is the one that is just C:\Program Files.

Ya I reversed those. I am responding on here while working and doing 3 things at once. I meant to say that because I have both I have 64 bit and 32 bit.
