Hi Blamdude,
You mentioned Jeff-Net Report Runner Viewer... the v8.5 version of it will run your v6 reports just fine. Did you speak with our support department about your problem? We provide support, even for trial users.
We have tons of documentation for configuring the Viewer, for use by network admins and power users. The Viewer itself has very little documentation, because it's super simple to use. If you know Crystal Reports, at all, you can use our Viewer. It's just a matter of turning on or off the security for entering ID/password, picking the report to run, and viewing it.
I'm guessing with Version 6 of Crystal Reports, you probably don't need an ID/password. The Viewer was probably prompting you for it, because you did not turn off that setting (just to the right on the main window).
Hope this helps clarify some of your statements/questions...
Jeff
