Getting Started with SQL Server 2012 Express LocalDB: SQL Server installation is either corrupt or has been tampered with (Error getting instance ID from name.). Please uninstall then re-run setup to correct this problem.

Hi all,

Yesterday, our Computer Team ran x64/SqlLocalDB.MSI to install SQL Server 2012 Express LocalDB in my C://Program Files/Microsoft SQL Server/110/LocalDB/Binn/ for me. This morning, I clicked on sqlservr.exe and I got the following:  SQL Server   Your SQL Server installation is either corrupt or has been tampered with (Error getting instance ID from name).  Please uninstall then re-run setup to correct this problem. 

Before I executed sqlservr.exe, I created 3 new tables (with their data populated by using "Edit Top 200 Rows") in a database "APG10pointsMMRP" of my Microsoft SQL Server 2012 Management Studio (SSMS 2012). Does this 3-Table creation cause the installation of SQL Server 2012 Express LocalDB corrupt or tempered?  Do I have to execute "sqlservr.exe" right afte it is installed? What else can cause this SQL Server 2012 Express LocalDB corrupt?  Please kindly help and advise.

Thanks in advance,

Scott Chang
