I downloaded rhino_en-us_7.0.19316.14005.exe (11-12-19 6:41pm) and rhino_en-us_6.20.19314.15311.exe (11-10-19 8:08 pm) and did a normal offline installation. When clicking the desktop icon for either one it would show the busy circle for a fraction of a second and then: nothing. Same thing if started from the start menu (Win 7). I deleted the WIP using the windows uninstall program facility and installed the 19295.11595. It started and ran OK.
Any thoughts? Anyone else see this?
