Count not load schema model from package. (Microsoft.SqlServer.Dac)
I haven't managed to solve it through SSMS, the only way that worked was through CMD: "C:\Program Files (x86)\Microsoft SQL Server\140\DAC\bin\sqlpackage.exe" /a:Import /sf:PATH-TO-BACPAC-FILE /tsn:SERVER-NAME /tdn:DATABASE-NAME /tu:USER-NAME /tp:PASSWORD
- Replace the upper-cases with your SERVER/DB info.
- Use correct folder (110,120,130,140...)
Please download the latest version of SSMS from here, it may solve the issue.
It seems a known issue the error you are receiving. On this Microsoft blog post, they were successful restoring to a SQL Server 2012 instance using SSMS 2014.
