This is a complaint, which is not usually the way to get help but I'm only telling it like it is.
To start with, the download page does not make it clear that BOTH the 1.7 zip file AND the language pack must be downloaded for languages other than German. There is an assumption that this is understood. It suffers from the basic defect that plagues all assumptions.
The only way for a non-German speaker to discover that both are required is to downloaded the English language version, unzip it and find instructions with reference to needing 1.7 a-prioi. It woud be much more useful if the download page simply said "non-German users, download 1.7 and your language of choice."
Also, in the English pack are 2 files called "installation.txt". Never saw such a thing before and it has no justification. There should be either one file of that name or two files with different names. But not two identically named.
The logical thing would be to combine them into a single file.
