Earlier today I accidentally associated an .ica file to Adobe Reader which is completely the wrong program to use.
Without explaining why, I don’t want .ica files associated to Adobe Reader. In fact I don’t want them associated with anything.
So I had to do some internet sleuthing as usual, and the solution that I found was a tiny program that does the quick work of unassociating the file type from the program:
The link to download the program (which does not require any install) is a mess to find, but you’ll find it under the “Attachments” section near the bottom of the page, titled “unassoc_1_4.zip” (this may change as the author publishes updates).
Here are the contents of the readme included with the download:
Unassoc (v1.4) for Windows 7 & Vista
Copyright © 2009 by Ramesh Srinivasan
Unassoc - Description
This utility helps you unassociate a file type quickly in your
Windows Vista or Windows 7 PC. Windows 7 & Vista do not provide a GUI
option to unassociate file types. That's the reason I wrote
this simple tool.
1. This utility requires administrative privileges to work correctly. 2. To be used in Windows® Vista and Windows® 7 systems only.
Any feedback or Bug reports about this utility can be sent through the contact form available in the Website.
