We recom­mend that you carry out the sug­gested steps in the order given. If the pro­blem per­sists, please cont­act our sup­port team and pro­vide as much detail as pos­si­ble about your hard­ware, your VR head­set and the ver­sion of CAD2VR® you are using.

Installation and Set-up

Pos­si­ble cause Solu­tion
Incor­rect CAD2VR® ver­sion installed Make sure that the instal­led CAD2VR® ver­sion is com­pa­ti­ble with the VR head­set you are using.
OpenXR run­time not con­fi­gu­red correctly Check whe­ther the cor­rect OpenXR run­time is selected.
Exam­ple: For Meta devices, the Meta OpenXR Run­time must be set as the active run­time in the Meta Hori­zon Link app.
USB cable not compatible Use a USB 3.x cable and test a dif­fe­rent USB port.
USB power-saving opti­ons enabled If neces­sary, disable the power-saving opti­ons for USB devices in the Win­dows Device Manager.

Pro­blem: The ‘Set Meta Hori­zon Link to active’ but­ton does not respond or remains greyed out.
