file association for non-portable use

Hi,
since I mainly use the portable apps on my home pc (I know this is not the intended use for it) I would like to associate some file types directly with the right OpenOfficePortable App. But this seems to be not easy/impossible. All these commands always opens the filter selection first:
OpenOfficeCalcPortable.exe "%1"
OpenOfficePortable.exe -calc "%1"
OpenOfficeCalcPortable.exe -calc "%1"

So, is there another solution than using soffice.exe -calc "%1" or scalc.exe "%1" directly?

EDIT: ok, I've found my problem: I testet it with a corrupted file, so that OpenOffice didn't know how to open it and started the filter selection. The first solution (OpenOfficeCalcPortable.exe "%1") works good now.

@Moderator: you can delete this topic. On the other side: perhaps anyone has a similar problem...
