Can't print HTML document using Runas with elevated privileges under Windows 8.1

Hi all,

i have a process, its job is to print an html file using ShellExecute and "print". I have to launch the process into a runas session (with Super Admin privileges) for specific reasons.

When I run it with runas, the print failed with the message "There was an internal error, and Internet Explorer is unable to print this document"... (previously i had an other message, but connecting to Super Admin account, and return to user one solves the problem)

When I launch the process with standard privileges the printing works.

The OS is Windows 8.1 pro 64 bits. Work on 8.1 32 bit

Thanks for help.
