Thanks Andrew. That does work, except that it forces ALL USERS to export to CSV instead of Excel. I was hoping it would be available at the command line level. I am also posting the instructions here because it took a while to find them buried in an enhancement document.
If you don't have one already, create an ssi2xl.ini file in your x:\Softrak\System folder (where 'x' is the mapped drive Adagio is installed to) and enter the following settings, as per your particular environment.
[Initialization]
ForceCSV=1
NOTE: If you have Excel installed but want to use a CSV view instead you must have this setting. The setting is global to all users. Therefore, a site that has some machines with Excel and some with another viewer, say Open Office, would not need or want the setting 'on' unless they want ALL stations to use a viewer even if they have Excel (i.e. stations with Excel who wanted to use Excel would not be able to).
I am also VERY interested in an .ini setting that suppresses the Startup-splash screen for Grid View if that is a possibility.
Thanks.
