I am having a similar problem also. Once it minimizes to an icon in the tray, it cogitates for a while, then comes up with the intallation error log (see below).
It installs the expreso and m2mstudio folders, with the proper contents. Both programs will run if run from the folder. I gather there should also be two other folders.
No icons are installed on the desktop, and nothing appears in the programs list.
regards
Graham
