visual studio 2022 – Setup Failed when installing SQL Server Integration Services Projects (Error 0x800703F6)
I am trying to install SQL Server Integration Services (SSIS) Projects extension for Visual Studio 2022, but the setup keeps failing with the following error message:
One of the files in the registry had to be recovered by use of a log or alternate copy. The recovery was successful.”
Question:
- What can I do to fix this setup failure?
- Is there a reliable way to manually install SSIS Projects, or fix the registry problem causing this?

I have already tried:
- Closing conflicting processes (like PerfWatson2).
- Restarting my machine.
- Running the installer as Administrator.
- Repairing Visual Studio 2022 installation.
- Trying the latest SSDT installer manually.
But I still get the error 0x800703F6 during setup.
My setup:
- Windows 10 Pro 64-bit
- Visual Studio 2022 (latest updates installed)
- SQL Server Data Tools (SSDT) partially installed
