Hey all!

I am having trouble updating an old maxst project after going back to it a few months later. I decided to try a fresh project to find any SDK related issues and immediately I am confronted with this error. This is  a fresh project trying to Play In Editor the ImageTracker MAXST sample scene. Please see image for error and weird effect on camera.

Any help or insight would be greatly appreciated.

Thanks for your interest in our MAXST AR SDK.


We can't understand your exact problem with the text.


Is the problem caused by building the sample app of MAXST AR SDK 5.0.2?

So., Could you please share more specific information about your development?


If our team can get it we can help you more easily.


Best regards,

Yes, this problem happens when I try to run the sample scene of MAXST AR SDK 5.0.2 in the Unity Editor. Also, when I try to run the sample application on an android phone it doesn't request camera permissions and so the camera doesn't initialize.

Does that help?

This error is not related to the MAXST AR SDK.

But, this error is related to problem of MS Visual C++ Runtime Library.


You should uninstall all versions of your current C++ Redistributable libraries through your Windows Control Panel.


Please reinstall to C++ Redistributable libraries through the bottom link.


Finally Please check out the minimum development environment.

Awesome! Thank you! That solved the crash!

Now I am getting these errors about loading MaxstAR.dll and missing dependencies.

I tried the advice from this but no luck so far.

Plugins: Failed to load 'Assets/Plugins/x86_64/MaxstAR.dll' because one or more of its dependencies could not be loaded.
maxstAR.AbstractCameraBackgroundBehaviour:Awake() (at Assets/MaxstAR/Script/Wrapper/AbstractCameraBackgroundBehaviour.cs:71)

I can make a new topic if needed.
