Hi anonymous, 32-bit sqldiff.exe runs just fine on my 64-bit Windows 10, that is Microsoft Windows \[Version 10.0.19043.1288\] . Can you be a bit more specific on your diagnosis "does not start" and "is not compatible"? If you expect a graphical user interface, there isn't one. It is a command line utility. Open a CMD.EXE window and run `sqldiff.exe --help` for more information. ~~~ -- Kind Regards, Kees Nuyt ~~~
