Connection lookup for MS Access and MS Excel files with trouble

[jochenwezel]

• Lookup of right and working provider (auto-lookup, oledb, odbc) doesn't work
• Very similar implementations for MS Access connection provider lookup with or without db password should be refactored
• Lookup of current MS Office data providers OleDB doesn't work for latest office releases
• Installed MS Acces data provider (at x64) detected, but not working
• MS Access data provider lookup doesn't reflect differences between .mdb and .accdb files (Jet OleDb 4.0 never talks with .accdb)
• In general, some more testing for stable operation of connection lookup of MS office files suggested
• Medium trust level execution should also be checked
