Assembly with name '***' already exists

August 11, 2020 - 8:52am #1

I'm not sure how to fix this error, this error occurred after I upgraded my projects Unity version from 2018 to 2020. I've resolved most of the issues that occurred but I've been unable to find the solution to this issue. I've attached an image below with all the error messages.

Assembly with name '***' already exists

Hi,

Strange occurrance. If you have installed 9.3.3 you should have under the Packages folder -> Vuforia Engine AR.

Do you have under the Assets folder, maybe a folder Vuforia? (not under the StreamingAssets)

In regards to the errors, you somehow still have an old Vuforia version, as with 9.3.3 the DefaultTrackableEventhandler.cs does not contain ITrackableEventHandler

Thank you.

Hi,

I believe you have now 2 Vuforia folders installed. 1 through packagemanger available under Packages and another that was with the project from 2018.

Please delete the folder Vuforia under Assets.

Thank you.

@mcotora I don't think that's right as I have no Vuforia folder in the package manager folder (see image below). What I did do was delete the '*.asmdef' files and while that got rid of those particular issues it gave me new errors (see image below). 

 

Could you please advise on how to resolve the new errors? Thank you

 

Edit: Oh I think I've found a solution but I'm not sure how to upgrade Vuforia in Unity 2020.1.1f1.

[Unity > Project Window > Vuforia > Version] tells me I've got 8.3.8

[Unity > Window > Vuforia Configuration] tells me I've got 9.3.3

 

I tried directly downloading the Vuforia SDK but that doesn't work, I get the following message "Nothing to import! All assets from this package are already in your project."
