Problem to upgrade from SQL Compact

Engaged Sweeper


For now several days, i tried to upgrade our old Lansweeper installation from SQL Compact to a more recent release on SQL-Local. 

We try to use installer but unfortunately  it didn't succeed. Install begin, LocalSQL service appear and then disappear and at the end, lansweeper is OK in version but database is still un SQL-compact-format.

We also tried to import database to a fresh installation without success.

Have any of you ever encountered this type of problem and found a solution?

Thanks in advance.
