Do not suppress DLL and DLO errors during installation.
I would suggest closing 3dsmax and vray spawer fully.
That should fix it.
Sorry I'm not sure of understanding well : you say "do not suppress DLL and DLO errors during installation. ?
I have no errors on FP Pro Installation on Render Node ; here are the step I m following :
On Render Node going to my : "C:\Program Files\Autodesk\3ds Max 2014"
Suppressing all "ForestVray*.dll" (20 to 36)
Going to "C:\Program Files\Autodesk\3ds Max 2014\plugins"
Same on Max 2016 versión
Launching Forest pack pro 5.4.1 Setup Wizard
User Agreement OK
Select install type => Render Slave Mode
Select component to install => Default FP Pro Plugins 64 bits
Install OK WITH NO ERRORS
Launching 3D max 2014 + Vray 2.4
Opening "test2.max· scene generated with Workstation + FP Pro Author 5.4.4 (with no problems at render time) => only basic geometry scattered with FP Pro and no texture.
Launching render on render Node
1st warning : "Forest Pack is configured to use a local License, but there are none available. please use License manager to install and authorize it."
2nd warning : "without a valid License, the Forest objects cannot be edited or rendered"
Render Node is rendering no Forest Pack objects ...
Thx for any helps ...
