Here are some things you can try that might help you out:
Some NVIDIA drivers have been reported to cause problems with OpenCL. Please do not use the following drivers with our products as they are unsupported by us.
On some occasions errors within our products are due to cached shaders that the driver hasn't compiled correctly or are corrupted in some way. Whenever you install a new driver we always recommend that you perform a clean installation and delete any cached shaders if they are present on your system.
Performing a clean installation of your drivers and deleting shader cache is simple and you can learn how to do it on the Clean Driver Installation page.
If you are still having issues, please contact us! You can reach us via e-mail at: support@knaldtech.com
We are unfortunately unable to support any kind of virtual machine for use with our products. This is due to GPU driver functionality and hardware acceleration being severely limited in such virtualization scenarios. Please see the minimum requirements for more information on the minimum and recommended specifications required needed to use our products.
In the case of any of these issues, please check the following:
