WPF (XBAP) application not trusted on some machines butother get a prompt and can run the application

Question

I'm having an Issue with a WPF file not running correctly. On some machines it starts a security prompt shows up and clicking ok lets the application run fine. but on other machines (some with an identical set up because the machines are all imaged the sames on this side of our network) no security pop up, just "Trust not Granted" I've Placed a Log below. I've tried things including but not limted to, deplying it directly to iis, to a file location and moving it over,( all using clickOnce) i have Fullpermissions checked, ive tried signed and unsigend, with passworded and unpassworded pfx.

I don't have the ability to modify the IE settings for the trusted sites and the like ( but I don't think thats the problem because the machines that work and the ones that son't should have the same set up)

I'd be greatful for any help. Thanks.

Answer 1

Here's the script I use to make all XBAPs on our internal network run as Full Trust. Usually I place this in a batch file and send users the link to the .bat if they email me about Full Trust errors

%systemroot%\Microsoft.NET\Framework\v2.0.50727\CasPol -q -machine -addgroup All_Code -url http://InternalWebServer/* FullTrust -n XBAPSecurity -polchgprompt off

Just replace where it says InternalWebServer with whatever your internal web server root is
