Here's How:
1. Download the free unassoc.zip file and save it to your desktop.​
2. Right click on unassoc.zip (On Desktop) and click Open.​
3. Extract both files to the desktop. (See screenshot below)​
4. Click on the Unassoc.exe icon to run the program.​
NOTE: I would recommend that you put these two files in a new folder and save them in your C:\Program Files folder, then make a shortcut for the Unassoc.exe to use.

Hi, I have been trying desperately for 3 hours to remove the association of the file type .INS from the program "Inspiration" (Document Mapping) so that I can run an .INS file as an "install shield script" file. I tried your tutorial and, sure enough, in the control panel, the ".INS" file type is no longer associated with Inspiration. However, when I look at my downloaded copy of a new program that I want to install that includes the .INS file type, it is still associated with Inspiration! It is EVIL! Can you help me? Thanks!

Hi Elisabeth,

Welcome to Vista Forums. :party:

If you installed a program that added the .INS extension, then you can reinstall it to add it back so you can unassociate it.

You can also right click on the .INS file and use Open With to select a EXE program to use to open it with.

Hope this helps,
Shawn

When I run the program and find the file I want to unassociate the Remove file association (User) is grayed out. What else can I do do unassociate.

.001 from 7-Zip? I do not see a file extension listed for that in 7-Zip. :confused:


Anyways, you can unassociate it by: :)

Hello Bluefire, and welcome to Vista Forums.

You might download and double click on the REG file I attached below, then restart the computer to see if it may help. It will remove the registry entries for the .blob file extension to hopefully unassociate it for you.

Hope this helps,
Shawn

Sorry, it doesn't work, it appears "Impossibile importare C:\...\Default.reg: non tutti i dati sono stati scritti correttamente sul registro. Alcune chiavi sono utilizzate dal sistema o da altri processi."

Which means: "It is impossible to merge C:\...\Default.reg: there are some data which are not correctly written on the register. Some keys are being used by the system or some other process."

  6. On the Edit menu, click Permissions.
  7. Click Advanced, and then click the Owner tab.
  8. Under Change owner to, click the new owner, and then click OK.
  9. Repeat for the other keys in that folder
  10. Try running that .reg file again, as instructed by Brink
