What if you lost your password to Impulse and what if you gave Impulse a fake email address during registration. Who could be so stupid ? But hypothetically... what could you do, if you wanted to migrate to another machine ?
Use regedit.exe, locate \HKEY_CURRENT_USER\Software\Stardock and export this folder onto a USB stick or some such.
On the new machine just doubleclick on the created registry export file and ignore the warnings.
It worked for me.
