There are alot of settings in all the versions of IE & windows, that may cause problems for users attempting to run xbap applications, particulary in fulltrust mode.
I seem to have gathered a long list of such cases during the last year. However I'm pussled by this one exception, which occurs on a user on one of my systems, and was hoping that maybe someone here could point me in the right direction.
This application runs on all the used version of windows, and IE6 -> IE9, without problems so there is nothing wrong with the deployment/xbap it self. The user gets the errorlog / stacktrace below. Have anyone of you encountered this vague trace, and know what the issue might be? This user is running IE8 & W7.
The user have the proper certificates installed in trusted root authorities & trusted publishers. The site in question has been added to list of trusted sites. Xbap has been enabled in IE.
URLs, publickeys, appname etc have been scrambeled.

I should have answered this one when I "solved" the issue.
In the case above there was an issue with the client computer, a change of disk, re-install of OS etc solved the trick.
What the issue was, remains a mystery ;)
