I'm having some difficulties using the hyperlink tool (ControlsMapHyperlinkTool) in ArcEngine. Does anyone have any experience with it?

It looks like it behaves correctly except that every time a user clicks a hyperlinked feature it shows a message saying "Unable to launch hyperlink". I'm using a "script" hyperlink and it performs fine in ArcMap. It doesn't seem to be trying to execute the script on click. I checked the IHotlinkExpressionProperties object and the Expression property is set correctly. Any thoughts? Thanks!

    I'm not sure this is relevant since it's been a while since I've touched ArcEngine, but what version are you using? I think there were major improvements between 9.3.1 and 10 which would probably make all the difference here. – nagytech Jun 17 '12 at 9:51

Might be a file association or system environment variable issue on the users' computers (or Citrix user profile if running through that).

Pick a user guinea pig and see if the script can be executed manually.
