When I hooked up my wife's digital camera to my Win7
computer, I decided to look at some of the photos before
copying any to the Hard Drive.

I use IrfanView to look at images on this machine, but when
I dbl-clicked one of the camera's JPG files, the Windows,
built-in app (Windows Image Editor?) came up and displayed
the photo. I close it, and looked again in Windows
Explorer. All the photos showed as "IrfanView" files. I
right-clicked on one, thinking that I would select "Open
with", but there was no such offering on the popup menu!

Does anybody here know why this would be happening?


File associations and icons used are separate things; they don't always
go together. It's very possible to have an Irfanview icon used for a
file type which opens with a different program. It all depends on the
history of which programs have swapped and changed their associations.

Unless you're using some third-party program to view the files in the
camera when it's connected through USB, then W7 will use its standard
list of file associations.

Go to Control Panel/ Programs/ Default Programs/ Associate a file type
... and list them out. Note which programs are assigned to these three
types;.jpe, .jpeg and .jp2

If I right-click on a JPG file, whether on the HDD or on the
SD Card while in the camera (thru the camera's USB cable),
Windows Explorer says "Opens with Irfanview". If I
dbl-click on one in the camera, it opens with Windows Image
Viewer. If I dbl-click one on my HDD, it opens with
Irfanview.


So, which program is assigned to each of the 4 file types that I've
mentioned? Don't do it the sloppy way; look at the entries as I've
advised you to.

Well, he did say it happened using the same file type (jpg) in both
cases...

I just searched for my camera cable (I've been known to accidentally
hide things from myself...), since I don't normally use it. I set my
default jpg viewer to Irfan View and looked at the files in the camera,
on the SD when plugged into the SD slot, and in the backup directory. It
went to Irfan view every time, so it seems that croy has a problem that
I don't have...

Note: I didn't reboot during this testing.

I should have mentioned: Panasonic ZS-3, not a Canon. And like croy, I
didn't install any camera software.


I thought maybe he'd got mixed between "jpg" and "jpeg". That happened
to me once; with XP, I think.

Maybe he'd be best following the old "reinstall" path. That's what W7
sometimes does to some of my installs; "The program may have installed
incorrectly. Would you like to reinstall?" I always say yes. I suppose
it has something to do with 64/32 bit mode.

In his situation I'd remove the file type and put it back in to be
opened with Irfanview.

It really has to do with file type associations, and should be solvable
there. It's too subtle for me, but I suspect that for some reason
Windows sees the Canon on a tether as a special kind of item and ignores
the usual association.

Don't forget that the drivers, although they are part of Windows, might
still be provided to MS by the manufacturer of the device.

In my opinion, the message "The program may have installed
incorrectly..." usually results from an installer program that doesn't
return the approved status code when it completes. I most often ignore
the message, and nothing bad happens... And it has never been limited to
32 vs 64 bit software on my computers - mostly just older or free
software :-)


I've just followed your example, using two cameras; one a Samsung bought
last week, the other an old Packard Bell from 8 years ago.
I don't use any supplied software with either of them.
The Samsung has been used several times through USB on this PC; the PB
one never, and W7 installed drivers for it and also had to scan and
reformat the SD disk before handling.

Both went A OK. They show as JPG files on the camera, and after
uploading to my HD they still show as JPG files.
And both opened with Win Photo Viewer (which I have set for such).

I think croy should try the old reinstall trick; but with Irfanview. I
use that too. It is excellent all-round, and I use it mostly with my
scanner.
