Fellow SQLers,
Ran into an install item (SQL 2016 Dev Edition with sp1). SQL install went well - sql engine, ssrs. Then SSDT.
Then needed to go back and install Integration Services. Install failed with the 1638 error. Log file showed "Cannot install a product when a newer version is installed."
Forums researched indicated it was the MS VS C# 2015 Redistributable.
On the box, there was MS VS C#2015 Redistributable x86 installed AND MS VS C# 2017 (x64) Redistributable installed. The only way we could get the install to work was to remove the MS VS C# 2017 Redistributable. The install built the MS VX C# 2015 Redistributble (X64) as well.
So my question is would you advise to manually reload the MS VS C#2017 Redistributable? The only other ODD thing we see on the box is SQL Server 2017 Import Export Wizard and I have no idea how that got on the box.
Thanks
MG
