downloaded latest version of SSDR onto new computer (win 10 (64)). Saw red error on COM 4 in CAT. Checking Widows system the error is caused because there is no driver present for FLEX port. Went back and reloaded CAT. Noticed error saying CAT required the driver and to reload. Downloaded entire package for second and tried to install CAT as the full install and again as a stand alone install. Both times got driver error.
