Windows 7: Missing Association

Missing Association

Hi All,
I have a similar problem with an application which hasn't an installation file file but it just come as an exe. In Vista and W7 32bit the file association worked properly but now it doesn't. The application is Processing and opensource programming language - and .pde are files made with it. Now when I try to associate a .pde file with processing.exe (Open With..) nothing happen and the files remain not associated!
I run a registry scan with TuneUp and this is what I get


.PDE file (*.pde)
The "HKEY_CLASSES_ROOT\.pde" key references the missing "HKEY_CLASSES_ROOT\pde_auto_file" key.


The "HKEY_CLASSES_ROOT\Applications\processing.exe\shell\open" key is incomplete because the "command" subkey is missing. Therefore, the "Open" action of this file type does not work.

Any solution?

Hi Kafka,

If I understood correctly, you are unable to open '.pde' files directly in the program called “Processing” even after you have associated the file extension with the program.

Thank you for posting the TuneUp registry scan result. :)

I can see that the program that you're pointing to isn't registered correctly.

In order to register the program you need to follow the below instructions:

  1. In regedit (type regedit in search field then right click on regedit and then select the option Run As Administrator): Navigate to HKEY_CLASSES_ROOT\Applications\processing.exe\shell\open and create a new registry key “command”.
  2. Then go to the “command” subkey(now you should be under HKEY_CLASSES_ROOT\Applications\processing.exe\shell\open\command)
  3. Then right-click on 'Default' from the right pane and select 'Modify'.
  4. Add the actual location of the executable Processing.exe under Value data:, hit OKand then try and re-associate the file type as you normally would.

This will definitely work for you!

I fixed it this way : I deleted the "pde_auto_file" key from "HKEY_CLASSES_ROOT\.pde" , then I associated the .pde to the application and this it time it worked!

So this is something I know I do (why? I don't know...). Do people associate others on this forum with their avatars? I know I do. Like I always picture Shawn as this alien guy, and John as Dr.Evil. Some of the others, I just always see them like that... Anyone else do this? ~Lordbob
