But that's exactly what the job of the power supply is.  The EasyProg is
trying to make Vdd one voltage and your power supply another voltage.  At
best nothing blows up.  In any case programming is unlikely to work.

So have you tried it without the target board powered and it still didn't
work?  Keep in mind that the EasyProg can only source a few 10s of mA on
Vdd.  If the target works with the ICD2 and Vdd doesn't require too much
current and doesn't have too much capacitance, I'd expect the EasyProg to
work with the same target circuit.
