P: Allow users to change the UI language without having to purchase multiple licenses

I can tell you, Juan, because I tried. Being a nosy IT guy I of course took the en_GB locales folder and copied it over to my German installation that had only a de_DE folder sitting there. Aswer part a) yes, I was able to select English (GB) in the settings after that. Answer part b) no, it isn't that easy. After a restart PS recoginzed an unlicensed language pack, wouldn't work. So I deleted the folder again.
Proves that technically it is very easy. It's only a matter of license and sales policy. I am quite an Adobe product fan. They have great software. But I am getting a disgruntled fan more and more. Issues with LR 4, Premiere Elements 10 I had to return because it couldn't handle my regional settings properly and would damage its own project files by mixing commas and semicolons for separators, issues not really well handled. Now a language pack that apparently is supposed to cost as much as the product itself? Sorry, the product is expensive enough as it is. I'd be willing to hand over another say 20 €, but not several hundreds. I am after all, not making money with my photography, at least not enough worth mentioning, alas. And Elements is just not the same.

The point is, all is needed to change the language of the program are the locale files in the folder C:\Program Files\Adobe\Adobe Photoshop CS5\Locales\**_**\Support Files (Where **_** are the different language_COUNTRY packs) and the possibility for the user to select the Language in the prefs window.

CC users can do that. As I said, Amiga user could do that decades ago. Adobe should allow all user do that (download language packs and select them), not only CC users.

I wonder what happens if you copy, lets say, the de_DE folder from a computer with a German version of PS to a computer with, lets say, a Spanish version (same software version, of course). Would just the presence of the new folder and files allow the selection of German in the prefs the next time you run PS?

Half an hour later - there actually seems to be a way to change language easily in Creative Cloud, through the Applications Manager.

I just gotta say I agree. I bought the Creative Cloud package, and must've missed the language option, assumed the software would be in English, but now I'm stuck with a Swedish one which is, to me, quite literally foreign.

I just purchased my PS CS6 upgrade in German and was surprised I couldn't switch it to English. Yes, I rememberd then that there was this issue. Stupid if you ask me, and unfair. I don't do more work with PS just because I switch languages, so why would the second license be justified? Language packs should be free or available at small charge max.
Yes, cloud would be an option. But I just decided against it. I only use PS, the upgrade costs far less then the cloud subscription.

Christoph's addition about Creative Cloud is a welcome solution for the users that can go that route, but makes this issue even more hard to swallow for users of Perpetual Licenses. Note also that CC allows a mixed OS installation (one Mac, one PC)

Geez, you're right. I suppose I wasn't on the same page with the rep I spoke with a few days ago. Indeed, all the apps are included in the subscription price and so my "above" complaints were so much hot air.

Thanks, christoph, for helping me resolve that. I appreciate it very much. Indeed, it seems that the Cloud is the best bet for her!

I was told by an Adobe representaive that the individual applications must be purchased when using the Cloud. The rep said all the apps can be downloaded as 30 day trials through the Cloud, but one must eventually purchase them if one continues to use them after 30 days even though one has a Cloud subscription.

It's quite possibe that Adobe representative was in error. Because if they were then I'll get the cloud for my niece.

I'll call Adobe and ask them again. Thank you very much for bringing this to my attention!

The Cloud license is a subscription, so yeah, one has to pay the periodic fee as long as one wants to use the applications – but this is not »extra« as one does not need to buy the stand-alone application beforehand.
And the monthly fee is naturally much less than the price for Photoshop’s full version.

I am wary of the concept myself but Adobe’s reasoning might be that people could work with a program indefinitely and never pay Adobe anymore if they are satisfied with the version they purchased – but they prefer a constant and reliable stream of small payments.
And to motivate users to switch to this model they offer (relevant) benefits – like use of the different language versions.

That indeed helped. At the end it was said that an application will launch in the language to which the operating system is set. I intend to get my niece Win7 Ultimate which will allow her to select Russian as a language for the current logon user. I'll advise her to have two logon users, one for English (the system language) and one for Russian.

Regarding Creative Cloud, I'm not sure why I have to pay extra every month (the subsciption fee) to change Adobe application languages. I realize that some Adobe applications, perhaps most, allow one to change languages readily however, the "standalone" Photoshop Extended is not such an application, iirc.

Regarding my statement that Adobe specializes in vauge "explanations", I've come to see that, in some cases, it's a matter of my wanting to know "G", but to know "G" I need to know A, B, C, D, E, and F and some of those may not be Adobe related but Windows 7, or "other" related. So in some cases my ignorance regarding that is to blame.

It's still frustrating to read descriptions which, intentionally or not, mislead. For instance, since Creative Cloud is subscription based and may cost one $79.99 per month, I assumed that one could download any application available and use it for as long as needed. This isn't transparently addressed in the video tutorial, nor in the text advertisement. They both say you can download any application in the Cloud and use it. What they don't say is that the application is a 30 day trial and after the 30 days one must purchase the application to keep using it. That's more than misleading advertising. I wonder how many people purchased Creative Cloud only to find out they were paying for Adobe to advertise Adobe products? How many people, including professionals, really need the ability to integrate so many devices? It seems manic to me. I know some professionals and some non-professionals may have a need for it, but it's not an "everyone's got to have this thing" and that's what it's pretending to be.
