Photoshop CS4 - How to install both 64 and 32 bit versions on XP 64

Question

Hello-
When I installed Photoshop CS4 along with the other apps on CS4 Web Premium I thought that both versions of PShop would be installed by default, but that was not the case with my installation; only the 64 bit version was installed.
Now I would like to install the 32 bit version but when I try to do it through setup I am unable to check the box. There is a list of "Installed Products" and then "Available Products"; the only thing under "Available Products" is Photoshop CS4, but I am unable to check the box.
Any ideas on how I can install the 32-bit version? I want it for the GPU acceleration and to use certain plugins.
Thanks,
Paul

Answer 1

a)re: built for XP64 - note that I said "gave the [erroneous] impression," meaning that someone could plausibly infer that PSCS4 64 will not run reliably on XP 64, which is categorically untrue. I am NOT saying that there are not people who have had problems and will continue having problems with PS CS4 on XP 64.* However, I am personally attesting - having worked with PS CS on my XP 64 system a lot since buying it this week, including continuously since I reinstalled last night ( I tend to work at night) - that PS CS4 runs gloriously on XP 64, INCLUDING the OpenGL stuff once you patch the reg via the link I posted (which, by the way, would have been a valid answer to my question).
On that note, telling me stuff that I already know is NOT a valid answer. Further, as we have seen, my running this on XP 64, as opposed to Vista, was irrelevant, if only (but not really only) because that is not the system to which my question referred. How did telling me about Vista help? If you don't know what to do with XP 64, then you don't know....I didn't know either, at least when I posed my question. Your reference to Vista was POINTLESS.
b) re: installing to non-default directory. I have been doing this for so long that I can't remember not doing it, and I have never, ever had a problem like this, and I do have other dual-bit depth apps. This should be a non-issue. If I thought it was relevant I would have mentioned it, but in light of what I just said, it did not seem to be a factor. Crikey- CS3 is in that same directory! Why would Adobe's installer get confused? They are the same structures, i.e. %disk%:\Program Files, %disk%:\Program Files (x86). If you knew things that might cause my problem - you didn't-you might have asked about my install.... Instead, you told me what anyone who had read my question would already know that I knew, namely that there would be two different locations for the two different versions. Incidentally, and here's good intel here, when you do get them both installed, you get BOTH versions listed in your Adobe CS4 whatever edition programs folder. Right there! So, if you had known what you were on about, you would have realized that there was NO WAY that PS 32 was mysteriously hiding somewhere. This is another clue that you knew nothing about the subject you were purportedly answering!
So why, why, why am I picking on you? Because there was a time when you could post a simple question on the internets and some helpful soul would take the time to actually read and consider the question before giving an answer that, even if not ultimately fruitful, was at least in the freaking ballpark. But those days are gone** and even though I know that and I expect nothing, I posted anyway, and along came you, with two heaping helpings of SQUAT in terms of useful advice. What the hey? Are you that bored that you just dole out crappy advice? Watch more TV or something!
Jeez!
Thanks,
Paul
*My relevant system specs are as follows, for those who may want to give XP 64 a shot: and/or are having problems:
XP 64 SP2 ( there is no SP3 for 64 and parenthetically I will note that CS4 on XP 32 SP2 runs fine even though you get a warning on install that it is supposed to have SP3 installed)
8 GB RAM
AMD 64X2 5600 on AMD/ATI 780G Chipset with dual integrated ATI 3200 Graphic plus an extra ATI 3400 card running three different monitors (2 on the 3200 and one on the 3400). On my setup PS likes to enable and actually work with the OpenGL stuff when I launch either/or the 64 or 32 bit version on the monitor that is attached to the 3400 card. After that I can drag the app anywhere I want and it works.
** in July, as myself and my girlfriend were getting ready for our vacation, we posted on a location-specific travel group to ask if people knew if the hotel we were staying at had a safe for our laptop. We got like thirteen responses, all more or less to the effect that we should leave the laptop at home when we go on vacation. Not ONE answer about the hotel! WTF???
