Portable version... makes registry changes when run?

[ilcaa]

hello, I work in a corporate environment with very strict  security features on our desktops.  i cannot install applications, BUT i am able to run some portable programs when they dont make changes to registry...  (i find some portables make additions to registry, some do not) 

does QM need to write anything to registry when executing, building Macros, running exe or toolbars, menus, etc from a portable installation?

thanks for any help
