I accidentally changed the program associated with the .snk extension

Wh开发者_StackOverflow社区ich program should be associated with the .snk extension.

I accidentally changed the association and don't know what it was prior to my change.

I want to set it back.

As already mentioned by Neil, there is no program associated with .snk files. What you can try doing is cleaning up the registry.

Open Regedit, navigate to the HKEY_CLASSES_ROOT node, expand it and scroll down till you find the .snk suffix. Make sure it has no data under that key, except for the (Default) value which should be VSTA.snk.9.0, which is a redirection to the application keys further down the same branch in the treeview.

I've also got other versions of VS installed as well as VS2010, i'm not sure what its value should be if you only have VS2010, i would look to see if you have a VSTA.snk.10.0 key.

From Explorer, open Tools, Folder Options. Scroll down the list of file types until you find the .snk extension. Then click Restore.

Note that there is no default program associated with the extension on my system, but it says it's of type Visual Studio Strong Name Key File.
