Unity 2019.2.13f1 Faceinfo problem Help

Hi all, i have installed TextMeshPro free Version 2.0.1 and i have this error :

Library\PackageCache\com.unity.textmeshpro@2.0.1\Scripts\Runtime\TMP_FontAsset.cs(84,16): error CS0433: The type ‘FaceInfo’ exists in both ‘TextMeshPro-2017.3-Runtime, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’ and ‘TextMeshPro, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’

and second line:

Library\PackageCache\com.unity.textmeshpro@2.0.1\Scripts\Runtime\TMP_FontAsset.cs(90,17): error CS0433: The type ‘FaceInfo’ exists in both ‘TextMeshPro-2017.3-Runtime, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’ and ‘TextMeshPro, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null’

same error x 2.
My settings project is setting .NET4.x

I tried to downgrade TextMesh to the old versions but not solved the problem.
can someone help me?

Tnks for all.

This is likely because you still have an old version of TextMesh Pro present in your project. I am assuming you just migrated from Unity 2017.3 to 2019.2? If so, you will need to follow the following instruction about migrating from the Legacy versions of TextMesh Pro to the latest Package Manager releases.

See the following sticky post with intstructions.
