2 main issues I’ve noticed when opening the Application Portal:
1 – WCF Activation is not installed
When this is true, and you try access the portal you will get the following error:

To solve this issue simply installed the missing feature, and restart the IIS:
2 – Wrong .NET is registered in IIS

2. Run the following command to register the .NET: aspnet_regiis.exe –iru
3. Restart the IIS
