This is my problem and I tried to reinstall with latest version but it do not work.How to fix it. Thank you very much.
Hi @conghau.bdh
Which Revit Version your using?
And also do you have colorizer installed? If yes try uninstalling colorizer and restart your PC.
My Revit version is 2016. I uninstalled Colorizer and Dynamo, then restart and reinstall Dynamo, but it still don’t work.
Now, I can go to Dynamo windown, but nothing when I create new file or open file.
Many thank.
@conghau.bdh that is good news 
Now that’s not good. Can you show me screen shot of your Dynamo folders in this location C:\Users\UserName\AppData\Roaming\Dynamo
@conghau.bdh Your missing “Dynamo Core” Folder. Looks like it is not installed properly. Uninstall Completely Dynamo again Restart your PC and Install again Dynamo 1.3.
@Kulkul I don’t think it is because of that folder. DynamoCore folder ill only get created when you install some Packages while you are running Dynamo as a Standalone application (outside Revit) OR when you install some Packages from “Dynamo Studio.”
@conghau.bdh Can you show me the screenshot of your Dynamo folder in the “Program Files”?
I did, but it still does not work. (go to Dynamo windown then nothing)
But, I have another computer, and it works although it does not have Dynamo Core folder.
Thank you.
@conghau.bdh @Ritesh_Chandawar Sorry i thought that’s the culprit but may be i was wrong. Can you show as @Ritesh_Chandawar said Dynamo folder in the programfiles folder.
