Toad 6.5.0.2553: Open Options - Extensions - Place checkbox beside sql
Click Apply, click OK.
Double-click file in operating system - still associated with SSMS, not Toad.
Close/re-open Toad. Still no effect.
Looking at registry keys… HKCR.sql - is pointing at “ToadStudio.SqlServer.Beta.sql.6.5” - so that’s right
Looking at HKCR\ToadStudio.SqlServer.Beta.sql.6.5\shell\open - seems to be defined correctly
So maybe this problem is only on my machine. I do have SSMS for SQL 2014 installed. It’s always the thing that opens. Maybe SSMS 2014 is grabbing the extension some other way. Can someone who also has SQL Server 2014 installed give this a try please?
