I have downloaded and installed SSDT from Microsoft docs. The install was successful and I now have SSDT for VS 2017 installed - version 15.8.9 (as per screenshot)
However, I cannot create an SSIS project. There is no option in SSDT to do so.
When I try to open an old version of an SSIS package I get the below 'Unsupported'...
What else am I missing?
