Hello joshyates,

Unity 2017.2 has integrated Vuforia support so the issue you are seeing is Vuforia 6.2 interfering with the native integration SDK. You can activate Vuforia in Unity 2017.2 by going to Player Settings -> XR Settings and checking the box that says "Vuforia AR." You won't need to import the Vuforia SDK that is downloaded from our webpage.

Thanks,

My project was created in unity 5.6 successfully, built and deployed and all.

Now, after moving to 2017.2 and afer removing the unitypackage for SDK6.2 from as described above followed by enabling the SDK in unity 2017.2.b10 I am confronted with missing scripts and prefabs.

Now what? Where are the prefabs and vuforia scripts?

Herb

Hello Herb,

Your Vuforia objects are referring to scripts from the 6.2.10 Vuforia and not the version integrated with Unity 2017.2. You will need to update all of your Vuforia objects to use the integrated SDK versions. To add the objects, right click in the Hierarchy panel or navigate to the GameObjects top bar and scroll down to the section labelled Vuforia. In here you will find all of the GameObjects associated with Vuforia features.

We will be providing documentation for migrating from Unity 5.6 to 2017.2 in the future.

Thanks,

Hi, I got this error as well. Any solution to solve it?

If you are running into this issue you are liking either importing Vuforia 6.2 into Unity 2017.2 or you are trying to pull your 6.2 project into Unity 2017.2 with Vuforia 6.5.

For the first case, instead of pulling 6.2 into Unity 2017.2, navigate to Player Settings -> XR settings and enable Vuforia support to activate Vuforia 6.5 within Unity.

For the second case, refer to this article to migrate your project from Vuforia 6.2 to Unity 2017.2 with Vuforia 6.5 https://library.vuforia.com/content/vuforia-library/en/articles/Solution/migrate-vuforia-62-to-65.html

I'm having this issue too and it's not going away.

Edit: This is a confusing layout... Why are the posts all in reverse order?

I thought the first post was the last.

Edit 2: I got it working by following the guide. I didn't see it straight away because I usually go to the bottom of the screen on a topic and work my way up to find the solution faster, but missed it the first time I saw this topic (This layout really isn't a good idea).

I also found that changing from the "old" vuforia camera to the "new" one built into Unity now caused some issues. Description/fix is here: http://marclaffan.com/posts/25

Hey,

After changing the XR settings, where do I find the assets which are there in the pulled SDK package

Thanks

i got this same error too. can i just uninstall the unity and install it again ?

Hello make this:

https://library.vuforia.com/articles/Training/getting-started-with-vuforia-in-unity.html#betas

But what if we installed the SDK from before like idiots and now we are still getting the aforementioned errors? despite checking off Vuforia Augmented Reality in the XR settings?

I have the same CS1704 error and I just don't know or understand what to do. Can someone please tell me what to do? I'm a beginner and have difficulties understanding what I have to do to solve this problem. Thanks!

Is this gonna be fixed or what is happening here? Hey Vuforia.. please! :P There is already Unity 2018, soon 2019

Hello,

You're seeing error CS1704 because, your project is loaded with older Vuforia files, that are conflicting with the newer version the Vuforia. The error is pretty much self explanatory. All you have to do is, delete the older Vuforia files from your project. Deleting the files manually is such a mess so here is a simple workaround. 

Navigate to your project, then go to File > Build Settings... > Player Settings... > XR Settings 

In XR Settings, check the Vuforia Augmented Reality Supported option. This will import newer version for Vuforia into project.

You'll still see the same error there. Now, in XR Settings, uncheck the Vuforia Augmented Reality Supported option. You'll see a dialog box (Disabling Vuforia) asking whether you'd like to keep the Vuforia files or not. Clicking on Remove files will delete all Vufroia files from your project. If you wish to add Vuforia support into your project, simply check the Vuforia Augmented Reality Supported option again, this will import latest Vuforia files which no longer conflict with any assembly.

Hope this helps.

Cheers.

Hi,

After updated the vuforia to 8.1, i had lost the vufoira file in unity ,please make a solution for this.

Assembly 'Library/ScriptAssemblies/VuforiaScripts.dll' will not be loaded due to errors:

Unable to resolve reference 'Vuforia.UnityExtensions'. Is the assembly missing or incompatible with the current platform?

Hello @Rvicky,

Did you enable Vuforia Augmented Reality Support in Unity's XR Settings? File->Build Settings...->Player Settings...

Thanks,
