Default program

[Dex]

Cannot select programs to be the default program to open files with.


Right click a .txt file and select open with, I get a choice of wordpad,
notepad or notepad++. If I select 'choose default program...' an error
comes up with 'This file does not have a program associated with it to
perform this action. Please install a program or, if one is already
installed, create an association in the Default Programs control panel'.

Even although three programs are associated with it.

The Default Programs control panel only has certain programs in it to
use as the default (in this case Notepad++ isn't visible, only Wordpad)
and they are either programs that have a default built in to them or
programs I don't want as default.

This happens with other file types, like pdf, mp3, ini, rar, zip....


How do I get Win7 Ultimate to choose the default program without mucking
about editing registry entries all the time?

There is a browse button in the lower right hand corner of the Open with
panel. Use it.

Be careful that that "Always use this program" box is checked or
unchecked the way you want it.

There is a browse button in the lower right hand corner of the Open with
panel. Use it.

The open with panel you refer to doesn't appear, just the error.

OK, I see that I didn't properly understand what you said; I apologize
for that.

My only guess is that the related system software is messed up. Running
SFC might help, or even a malware scan might be needed.

*But* your best bet might be to wait for advice from someone else

....Meaning I am not an expert, or even mildly knowledgeable, here.

I did see that before posting here, but I don't quite understand the
answer given.

He says \DefaultIcon \+shell \+openas \command \+opendlg \command are
subfolders of HKEY_CLASSES_ROOT\Unknown, but you cant have 2 subfolders
with the same name.

Do all of them have %SystemRoot%\System32\shell32.dll,OpenAs_RunDLL %1
in them, or other string values?

 

[J. P. Gilliver (John)]

As others have said, there should be a browse option at the bottom of
the default list. But another way - though certainly not available with
all software - is to open the software in question, then poke around in
its options to see if there's an "always use this for .pdf files" or
"make this the default for ..." or whatever.

I suspect the space shouldn't be there, and that that's a registry edit
tip. (It _shouldn't_ be necessary to registry edit to fix this sort of
problem.)

There are two 'command' keys but they are sub-keys of different keys so
they can have the same name.

Here's my HKCR\Unknown tree:

Copied your keys and values, apart from the last one.

When I create HKEY_CLASSES_ROOT\Unknown\shell\opendlg\command it has a
default REG_SZ which I cant delete or rename.

Created another expandable string value REG_EXPAND_SZ with (Default)
name and the rundll32.exe... value

Still getting the error.

I have a 64 bit version of 7 Ultimate if that is any use.

I've checked on a 64 bit box and the keys are the same as 32 bit.
When you say you've copied my reg values that implies something was
missing or different with yours ?

I don't suppose it will make any difference but I've exported the
HKCR\Unknown reg key from a 64 bit Win7 box if you want to try it:
http://www.admin1.myzen.co.uk/Unknown.zip

I'm guessing you've already tried a system restore.
If you create a new temporary account does it still happen there ?

Only the DefaultIcon key was present, no subkeys.

That did the trick, must have done something wrong when copying.

In the Default Programs panel, go to the second item: Associate a file
type with a program. Go down to .txt, for instance, and click on it.
Several programs will be shown. If the program is NOT shown, click
on browse and find it.
