Unassociate a file type in Windows 7

I found the easiest way to unassociate a file type is to perform these steps:
1. Click start then all programs then accessories.
2. Right click command prompt and select run as administrator. If prompted for username/password, enter it.
3. In the command prompt type the following command:
assoc .pml= none
Note: .pml is the file you are trying to unassociate.
4. Press enter.
Voila, hope it helps!!

I need to unassociate .crc files; tried both methods suggested above in vain.
The Unassoc.exe ran and said the file type is unassociated now, but it stayed associated.
Nor did the command prompt do the trick.
What could the cause be and more importantly, how to solve this?
Thanks a lot.

Hello Georgey,

Did you also try deleting the file extension using the program in the tutorial? That will also unassociate it.

Hope this helps for now,

It's the same Unassoc.exe program at the link in step 1 of the tutorial on the first page.

Oh thanks I found and tried that before asking for help.
As I mentioned in my first post, it ran, said the file type was unassociated, but in fact it is still associated.
Anything else that might solve this problem?

Dont Work in indos seven ultimate.

Hi
This tool is exactly what I was looking for, but refuse to work on Wndow Seven ultimate French, SP" (clean install)

The error message is that
"This program run in Windows 7 & Windows Vista Only"... and I am in Windows Seven

Is that a way I can force it to do.

Thank you
Marie

I just see how to proceed with the command ligne, as suggeste by Georgy, thank you...

But if ever it is a way to use the Unass.exe, that would be fantastic.

Thank you.

Hello Marie,

It may have been an issue with your Windows not in English for the program.

I'm happy to hear that you got it sorted using the command line though.
