Missing reference dll on target machine

Hi all, i'm developing a little windows forms project and referencing system.data.sqlite (ver 1.0.92.0 assembly installed on dev machine)

In reference poperties "specific version" is set to false

Debug and Release are working fine on dev machine (obviously!) but not on target machine, the error says that the reference to system.data.sqlite ver 1.0.92.0 is missing; after installing on target machine the same version (from sqlite) the error persist.

Dev machine: windows 10 pro 32 bit

Target machine: windows 10 pro 32 bit, windows 10 pro 64bit

Thanks in advance

Edit:

Just missed to say: it's a single .exe application, no install.

SharpDevelop Version : 5.1.0.5216-0e58df71

.NET Version         : 4.6.01586

target .net: 4.5.1
