Allright. i guess thats the isse then. The Application also threw an error when the trying to save something to the registry in the security editor.

Now, how would i go to enable the clickonce file to get the required permissions ?

Thanks.

That is an question for someone who uses ClickOnce.  We do not use or support ClickOnce due to many issues (not unlike this one) that we ran into early on.  We use InstallAware for all of our distribution.  There are most likely a lot of blogs on the web that might be able to give you an idea here.

ok. thanks.
