My recommendation is purchasing a site lisense. The site license will include your organization logo with a link to your website (see http://www.genopro.com/buy/site-license/ for sample screenshots) and has no user limit. The site license is ideal for network installation because it does not require the user to enter a registration key. We also support a command line to specify the installation path (http://www.genopro.com/setup/command-line/).
As for specifying the default file save path, GenoPro does not support this yet. If you purchase a site license from us, I will add a new command line option /PathFileSave, to change the default save path at installation.
/PathFileSave
Example (assuming X: is your shared drive):
The other alternative is by manually patching the registry at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\gno to include the default file save path.
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ComDlg32\OpenSaveMRU\gno
