Windows 7 - Unable to associate file type to upgraded version of a program

I downloaded an upgrade to DxO Pro Optics. The old one, v6, was buggy so I upgraded to v7.1, which is in the v7 folder.

I can't associate my raw Canon files to DxO v7.1, probably because in regedit it says:

HKEY_CLASSES_ROOT\Applications\DxOOpticsPro.exe\shell\open\command it reads, under Data: "C\Program FIles(x86)\DxO Optics Pro v6\DxOOpticsPro.exe" ""1" [the extra quotation mark should be a percentage symbol (ie before the numeral one]

I thought I could change the v6 to v7 but I'm not allowed to.

I just open and close these things because I only know enough to ruin my computer.

Please help?

Hello pxfragonard,

Does the DxO v7.1 version have a separate folder of it's own in Program Files (x86) or Program Files instead of in the original DxO Optics Pro v6 folder? If so, you could use Open With to select the .exe file for the DxO v7.1 version to associate to the file type.

Are you able to install the DxO v7.1 version separately instead of upgrading from the older version? If so, you could uninstall them, then install the new version to be able to.

Hope this helps for now,
Shawn

Yes, Shawn, it does have a separate forlder in PFx86 and I have tried the Open With command to select the exe file, as you suggested. Nada. That's what's so puzzling.

I did install the 7.1 version separately. Both were on my system until I uninstalled v 6, thinking that would solve the problem. It didn't so I did a system restore before deletion and not only does the problem persist, I can't open the 6.6 version either though the raw files (that I want to change association to 7.1) are associated with that program.

The loss of the v6 doesn't bother me. It was awful buggy.

If you have not already, uninstall both of them completely, then install the new version to see how that works.

Are you able to at least open the files from within the program itself?

I have just uninstalled completely (both) and am about to reinstall.

And yes, I am able to open files within the program itself.

Odd though... I checked the registry and that annoying command is still there for DxO 6.6 which is supposed to have been removed from the machine.

Thanks again!

Here is a screenshot of my registry entry... see? It points to a program no longer on my machine. I don't know how to create the new command and then delete the old one, which seems the common sense thing to do.

That should be left as is since it's the way the program installed it as.

What file extension (ex: .jpg, .bmp, etc...) are you trying to have open with this program? That is what you should be using Open with or Default Programs on instead to change to open using the .exe file of the new version of the program.

I wouldn't change anything I don't understand, Sean. No worries there.

But I have tried repeatedly both methods you suggest with no result. The program is simply not recognized by either "Open with" or "Default Programs."

Puzzled as to why not... this is after a complete uninstall and reinstall, cold restart.

Yeah, but what file extension are you trying to do this with?

CR2 (Canon raw files)
