Issue: Playing after Installing Interhaptics SDK Package​

If you encounter the following error "DLLNotFoundException: HAR DLL file is missing" (in Interhaptics SDK 1.0.6 or lower) that means that one or more DLL files is missing from your PC.

  • You can use Dependency Walker on the HAR.dll file found in the Runtime\Plugins folder to identify the missing DLL.

  • Alternatively, you can locate the missing file (likely "ucrtbased.dll" from the Windows 10 SDK) and move it to the Windows\system32 folder (for 32-bit systems) or Windows\SYSWOW64 folder (for 64-bit systems)

Issue: DLLNotFoundException error in Unity on macOS​

Some DllNotFoundException: HAR assembly errors might appear in the Unity Editor console. These will not impact the building of the XCode project and should be ignored.

Issue: XCode error: No such module 'UnityFramework_CoreHapticsPrivate'​

This issue might appear if the XCode build has been done on another PC/Mac and then copied to another Mac to compile the app build. The simple solution is to build the XCode project on the same Mac.
