The latest version of the samples for 2017.3 should be 7.0.50. Could you try updating these and see if that resolves this issue?

Thanks,

Hi,

I shows 7.0.47 version

You should be able to open the file with NotePad on Windows or TextEdit on Mac.

Hello Strasza,

Thank you for your reply, I could not able to open "Version" File. Please Advice me What to do.

thanks,

Is this error happening with just the SDK, or after importing the samples? In the sample sample project you mentioned in your first post, could you open the file called "version" under Assets->Vuforia and let me know what version it says?

Thanks,

Hello sarathraja91,

I am not getting this error when running the Model Target sample on Unity 2017.3.1f1 or 2017.3.1p4. Have you entered a license key into this app? The Mars sample assets will not require one, but if you've entered an invalid license you would encounter this error.

Thanks,
