I recently changed laptop (Windows 10) ,and thought i would take the opportunity to download new release of Heidisql 10.3.0.5771 and install it; however i cannot get it work and to connect to MS SQL server environment. upon connection setting It is now providing a dropdown fording to select one of the 2 libraries : MSQSLOLEDB/SQLOLEDB. neither work for me. when I revert to an old installation of Heidi (namely 10.2.0.5999) it works fine and does not prompt me to select a Library. the sql server version is"SQL Server 2008 R2 (SP2) - 10.50.4339.0 (X64)". could you explain the main différences between 10.2 and 10.3 on that connectivity aspect (and why 10.2 works and 10.3 does not by default) . apart from this , HSQL is a great software .
