Make 32 bit Photoshop CS4 the default instead of 64 bit?

Oct 25, 2008 8:35 PM

It was a bit of a surprise to find that none of my 32-bit plugins would work with Photoshop CS4 x64. Most seem to work fine in the 32-bit version of PS though. Is there a way to make the 32-bit version launch by default from Bridge or when opening a PSD file instead of the 64-bit version?

    For the double-click opening, adjust your Explorer file associations under Extras --> Folder Options --> File Types. Pick out the PSD file type and then choose "Change" to assign a new file handler. For Bridge, similar procedures apply by changing the assignment in The prefs.

    You forgot to mention your OS.

    You have to set the file associations in Windows Explorer and Bridge Preferences to

    C:\Program Files (x86)\Adobe\Adobe PhotoshopCS4\Photoshop.exe

    I am having the exact same problem as the OP. Additionally, I have not been able to change the file associations. If I right click the file and choose "open with" followed by "choose default program" I can browse to the 32 bit version of the Photoshop executable in my (x86) folder, but it doesnt actually change. I have done this though the context menu in windows explorer, and the default programs applet in the control panel (as an administrator).

    I have also renamed the 64 bit PS executable to Photoshop.backup to remove it from the list of default programs. This does nothing however as I still cant change the default and PSD files now open in quicktime image viewer.

    Last thing I tried was changing the registry so that version 11 (cs4) is forced to point to the 32 bit executable instead of the 64bit version. This hasn't worked either.

    I haven't been able to find this extras -> folder options -> File Types menu that Mylenium mentioned. The OP indicates that worked for him.

    I am sure I am missing something really simple with the above solution but I cannot find it.

    I was able to change the preference in Bridge. That works fine now.

    Iam also using Vista 64 Ultimate.

    Thanks in advance.

    "C:\Program Files (x86)\Adobe\Adobe PhotoshopCS4\Photoshop.exe"
    is the 64 bit version, not 32 JJ. Doesn't the OP want to open in 32?

    That is the 32 bit version. The 64 bit version is in the Program Files
    folder.

    Right. I am ghosting one as we speak.

    Oh, is the process to run CS4 as 32 bit on a 64 bit OS? My assumption is a dual boot for 32 bit.

    When you install CS4 in a 64 bit O/S both versions are installed.

    That's right. And that means the 32 bit runs on a 64 bit OS. Duh! :D

    I would rather run the 32 on 32. And i assumed (I know, I know!) that would be the case. But obviously, you cannot install the 32 bit version on a non-existent 32 bit OS.

    Again, duh!

    Thanks for the clarification.

    In my defense, we deal with both 32 and 64 versions on XP and Vista by dual booting platforms that require testing on all four configurations.

    Please see post #6... "Jason Clough - 6:12am Dec 29, 08 PST (#6 of 15)"... I've been having this problem from minute one, and it's really getting old... I'm on Vista 64 Premium... BOTH versions install (as they're supposed to)... I can use wither one, but I *CANNOT* set either one a s the default in Vista... It keeps loading PhotoShop 7... I have completely removed PhotoShop 7 now... At this point, when I go into the "default programs" dialogue, I *CAN* navigate to the 32-bit version (just like before), but when I select it, the "default programs" dialogue does NOT add it to the list to select as the default. Before, it just kept going to version 7... Now, it won't go to anything... I just have to manually load PhotoShop CS4 (32-bit), and manually open the .jpg through the program... VERY aggravating! (same scenario for 64-bit version)... The question in posting #6 never got answered, and i think that's also where this whole thing started anyway... Any thoughts?

    Thanks, in advance!

    I think you need to clean up your registry!

    I use CCleaner ( http://www.ccleaner.com/ ).

    A lot of people are reluctant to use registry cleaners but this one lets you decide what it will look at, shows you the problems and lets you decide which ones to fix. It also prompts you to do a registry backup before fixing.

    i've used ccleaner, but the REAL way to clean up your registry is to format and reinstall. reg cleaners are band aids at best...

    Thanks for the help!

    I actually found a solution for this...

    http://windowsxp.mvps.org/openwithadd.htm

    It worked perfectly for Vista-64, for each of the three programs that would not populate in the "default programs" dialogue (PhotoShop was only one of them). After doing a LOT of careful research, I have discovered that this is a VERY common problem in Vista (regardless of the file-type and/or program that you are trying to set defaults for), but it seems to be plaguing the 64-bit version more frequently than the 32-bit version.

    I hope this helps others experiencing the same issues. ;-)

    If I can add a wish, it would make it a whole lot easier if the Help > About pages showed the version, and the 64 bit version is marked as 64 bit.  Also for the folder associations as well.  thx

    Thank You.  Too much experience with Win from 3.1 on, I guess.  Do you have any sage advice for the file associations for PS?

    I encountered this issue today as well when I installed Photoshop CS5, and discovered that my usual plugins do not work properly.

    They did work properly while running in 32 bit mode.

     

    Windows 7's extension definition sucks, that's why I rather work with the registry.

     

    So after a bit tweaking, I think I finally cracked it.

    The "Final Product" (if you will ) is two reg files for toggling 32 and 64 bit modes.

     

    A word of caution: This is what worked on MY machine (Windows 7 64 Bit) and I cannot gurrantee it would work on other computers, nor do I take responsibility for any damage that my occur. We are playing with the Registry here, so BE EXTREMELY CAREFUL.

     

    These codes assume Photoshop is installed in the default location. If you've altered it, make sure to modify the files accordingly first.

     

    Before attempting to use I recommend to create a restore point, just in case something may go wrong.

     

    Here we go:

     

    To switch to 32 bit mode, open a blank notepad page, paste the below code and save it as "fix.reg" (NOT TXT). After saving, activate it and you're good to go.

    32 Bit Mode
    Windows Registry Editor Version 5.00

    [HKEY_CLASSES_ROOT\Applications\Photoshop.exe]

    [HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell]
    "FriendlyCache"="Adobe Photoshop"

    [HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\edit]

    [HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\edit\command]
    @="\"C:\\Program Files\\Adobe\\Adobe Photoshop CS5\\Photoshop.exe\" \"%1\""

    [HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\open]

    [HKEY_CLASSES_ROOT\Applications\Photoshop.exe\shell\open\command]

    @="C:\\Program Files\\Adobe\\Adobe Photoshop CS5\\Photoshop.exe,1"

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\Insertable]
    @=""

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\protocol]

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\protocol\StdFileEditing]

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\protocol\StdFileEditing\server]
    @="C:\\Program Files\\Adobe\\Adobe Photoshop CS5\\Photoshop.exe"

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\shell]

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\shell\edit]
    @=""

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\shell\edit\command]
    @="\"C:\\Program Files\\Adobe\\Adobe Photoshop CS5\\Photoshop.exe\" \"%1\""

    @=""

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\shell\open\command]

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\shell\preview]

    [HKEY_CLASSES_ROOT\Photoshop.Image.12\shell\print\command]
    @="\"C:\\Program Files\\Adobe\\Adobe Photoshop CS5\\Photoshop.exe\" -p \"%1\""

     

    Now, if you want to revert the changes, do the same procedure with the below code, and it should make 64 bit the default once again.

    The 32 bit registry file you provided above seems wrong.

     

    Note that the paths all point to C:\Program Files instead of C:\Program Files (x86).

    I have both Photoshop CS4 and CS5 installed on my Windows 7 x64 system.

     

    Here are the default installation paths:

     

    C:\Program Files\Adobe\Adobe Photoshop CS4 (64 Bit)

    C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)

     

    C:\Program Files (x86)\Adobe\Adobe Photoshop CS4

    C:\Program Files (x86)\Adobe\Adobe Photoshop CS5

     

    Note that the 64 bit paths contain the string (64 Bit) and teh 32 bit paths contain the string (x86).  This is true on XP x64, Vista x64, and Windows 7 x64.

    Strange, on my machine both the regular and 64 bit version are installed under Program Files\Adobe (and not Program Files (x86)).

    Creat new .txt file and copy and paste the desired registry modification. Rename .txt file to .reg file and run.

     

    Enjoy.

    I have done this myself, since several of my plug-ins are 32 bit. Alll you

    have to do is go into your file type preferences folder in the Control Panel

    (in XP, that is the location, and change all file type preferences from PS

    64 to PS. For the first few, you will have to browse to the .exert file, but

    then it will be in the recent programs options that are offered.

    Windows 7 works differently and requires the registry modification. The file association doesn't seperate x86 from x64, it is only seen as "Photoshop".
