Interesting observation, Coolmo.
Again, icon color aside, everything works fine using the correct product and Profile using the Registry modification above (per Autodesk's KB, using YOUR app icon's Target path + switches) in Windows 10, and is something that can be modified using REGEDIT, GPO, Netlogon Script, or even included in your Acad.lsp using Vl-Registry-Write LispFunction like so:
Code:
(vl-load-com)
;;; Fix DWG double-click from Explorer
(defun c:FixDwgDc (/ key)
(vl-registry-write
(strcat
(setq key
"HKEY_CURRENT_USER\\Software\\Autodesk\\DWGCommon\\shellex\\Apps"
)
"\\"
(car (vl-registry-descendents key))
)
"OpenLaunch"
"\"C:\\CAD\\FOO.bat\"" ; <-- Your Target value here
)
(princ)
)
;;; Autorun for Acad.lsp
(c:FixDwgDc)
(princ)
Cheers
