Windows 7: Problems with portable progs as standard for

Hey there,

I have problems setting some portable progs as standard for certain document types.
And yes, I know how this usually works.

So this is the usual procedure:
the problem is step 5 - it does not show in the list after i selected it.
I also tried the system administration where you select the standard programs - also no success, same phenomenon.

I checked with another user account where a pdf wasn't associated at all and it just worked. but still not for the account i'm using. I can add other programs to the list of icons to chose from by browsing my files, even other portable ones.

I had this problem first with pdf xchange viewer, but it was mysteriously solved:
I was opening a pdf from the internet and I was asked to choose the program. I was able to pick the xchange viewer, even if there was no option to choose it permanentely. I then tried to open a local pdf and all of a sudden, the xchange viewer was listed among the available programs.

But the problem still persists for the open office writer for example.
I also tried to do the same with a doc because it worked for PDFs, but it didn't help.

Any suggestions on that? It really sucks cause it really disturbes your work flow if you can't just click on a document to open it!

Try to change under Control Panel
Control Panel\Programs\Default Programs\Set Associations
Select the extension then click on Change Program select the Program from the List

Hope it helps

I ain't got an english Windows 7 version so I'm not sure if I translate correctely, but that's what I meant here
when you click on change association it's basically the same procedure then if you select open with and sadly it also doesn't work...

anyone help?
