Language problem with Photoshop 7.0

I turn to you with the question regarding Photoshop 7.0. I have purchased this program from the physical person, and this is a German version. The documentation, package and the instruction are published in English, that is why I thought that this program is English version as well.
My question is: if I can install English version from different source using my original key? Does my original key contains all language versions of PS7.0 or just the German version?
I have registered my key on the Adobe website, and there is no information that it works only with the German version.
I know, that PS7.0 is not supported, but I really care about your kind professional advice. Thank you in advance.

BTW
On my back cover of CD is stickers with this info: PHSP,7.0,RET,IE... and then number. IE means International English? But why on CD I have German version?

Sorry, you are stuck. Each disk carries only one version.

Since 7.0 is four versions old, there is little you can do about it except try and get your money back.

Can I upgrade Photoshop 7.0 German to Photoshop CS3 Polish version? This is legal?

Thx for answer.

Sorry, bad news again. Before CS4 came out you could upgrade version 7.0 but that's no longer possible.

Why?

I still can buy upgrade to CS3 from authorized distributors and resellers in my country (Poland).

Examples:

And from Adobe site:

Maybe the policy is different with Polish distributors.

That still leaves the question of language though.

I suggest you ring one of those distributors and ask them if they can do German to Polish.
