The resolver will always try to install the least number of IUs satisfying the constraints available. Therefore if one version can satisfy multiple constraints only it will be installed.
If you want multiple versions of the same IUs to be installed you need to ensure that you have dependencies requiring each version.
The other thing you may want to look for if whether your IUs are singleton or not.

Ciao Guys :)
In our p2-based installer prototype we noticed a change in behaviour:
Where previous installations allowed for the installation of the same IU
with different versions a recent attempt would de-install older versions
of an IU if a newer one was installed...

Here's the question: Is this something p2 changed recently or should we
go looking for bugs in our code on top of P2?
TIA,
Ciao, hh
