Ok my problem,

I try to install an application from zenworks, this install run as unsecured system user. But this application need to write to the user maped directory and cant. So i use a subst U: C:\UVW to recreate the U:\ needed for the installation.

But now when my script is finish i need to copy files form C:\UVW to U:\ of the user. but this need to be done into "normal execution"

Is there a way to run an application from a script run into another application?
