I found the short way:

1. make a backup copy of "copydatabasewizard.exe";

2. edit "copydatabasewizard.exe" with an Hex editor;

3. search for "assemblyIdentity";

4. change "version" value (right of "=" char) from "1.0" to "1.0.0.0"

5. save change

And voila ! "copydatabasewizard.exe" works again !

Don't know why MS has an incorrect manifest embedded in that file, FYI version number must have 4 digits, not 2.

Ciao.
