Please help: Uncaught Error opening vl Nodes

[katzengold]

Hi!
I’m working towards a final version of vvvv/vl software for a theatre show.
Moving from my Laptop (Win 10 Pro Build…10.01.18363)
to the PC used to run the show (Win 10 Pro Build…10.01.18362)
i get a uncaught exception error, see below.
The vl Window show a red cross, see attachment.
The application runs, but occasionally freezes (maybe unrelated)
I cannot edit the vl nodes on the Show-PC, which is bad,
and the error messages are not trust-inducing…

Can someone advise?
Many thanks!

(vvvv versions are the same,
both setup.exe identical and boxes green/checked)
Heres the error Message:

Is that parallels or any other virtual machine? the error basically means that the OpenGL context for drawing cannot be created…

i would update windows and/or the graphics driver.

Okay, that makes sense.
Thank you!
(I use vvv/vl just for data shifitng in this case, so i hadn’t really bothered with display issues).

The machine in question is not a virtual machine but plain Win 10 Pro.
The Graphics card is a IntelHD 2000 (according to processor specs),
no WIN 10 drivers available.
Installed HD Driver version version is 9.17.10.4459,
lates i get from Intel is 9.17.10.4229 for win 8.

Should i just try and find another graphics card with win 10 support to use this PC
instead of trying around with old drivers?

On the other hand -
I’m mostly finished with the vl Nodes and don’t need to edit them on the target PC.
I could continue with vvvv patching to finish the project.

I wonder if the error described in the OP
might cause stability issues.
(I had occasional freezes, but that might be unrelated)
