Yes ... it will be interesting if OP can get monitor reading of 100 with previous 1.2.0
With PMP5, I've noticed that the default install directory for Win-7 changed from 5.0.6 to 5.0.8 to 5.0.10 as I experiemented with different versions. I don't know if i1Profiler will be similar, so you can have both 1.2.0 and 1.4.2 installed at the same time, or if the install over-writes the previous installation. It's probably possible to avoid an over-write.
