Iron & Google: Only display of english language results

I would like to readress the below topic again as I consider this an issue with the portableapps version of Iron. It does not happen with the portable version of Iron downloaded from SRWare.

Can it be that there is a connection between the language setting in Iron and the languae of the search result which is brocken in the portableapps version?

Thanks for your help,

IF you want to use Google as you standard search engine, you can do that only with google.com, not with google.fr or google.de etc.
No possibility to change parameters...= english language reasults are displayed first.
Rather useless if you speak french or german.

Yes, you can add other search engine, but I could not find a way to make them standard.

Any ideas?

Thanks for your help.
