I've got one user here that gets this error when trying to install a printer via iprint.
We have quite a few printers, located both here and abroad, and all are installed via iprint.
No matter what printer he tries to install, he gets this error.
It shows the error immediately after installation launch, no iprint install window is shown.

I've checked that the print spooler is running, and it is, and I've fumbled around looking for Internet Explorer errors, but so far to no avail.
He is authenticated to edir, and the printers can be installed by others.

Anybody that has an idea?
