I have isntalled VS2019 and installed SSDT from installer but I still get error when trying to open SSIS projects: This version of Visual Studio is unable to open the following projects. The project types may not be installed or this version of Visual Studio may not support them.
I have also installed Analysis services from nuget and EF6.
In the installer , I can see SSDT is marked as installed. Restarted both VS and pc.
What can be wrong?
