JavaScript Error: No Such Interface Supported Solved

January 19th, 2007

For everyone who has had problems with this JavaScript issue, I've found a solution!

If you've used JavaScript with Internet Explorer extensively, you know that there is a nasty little dialog box that shows its ugly head once in a while called "No Such Interface Supported" (NSIS).

Really informative error message, isn't it?

I was attempting to open a window using the window.open() method in JavaScript. Every time it tried to use the window.open() method, it displayed the NSIS error message. Grrrr.

Well, after ripping more hair out of my head, I came across a simple solution to the problem. The site isn't anything elaborate, but it solved my "No Such Interface Supported" problem completely.

Register two DLL's using RegSvr32: actxprxy.dll and shdocvw.dll. After you register those two DLL's, reboot your computer and try it again. The message should disappear.

Those of you who are getting this same error message, I hope the search engines pick this up and announce it wildly. It's an easy fix to a not-so-common problem.
