Rapture Pro

Hi all.
 
I've been having problems with my laptop installation so I've done a clean reinstall of everything Sonar related.
 
Mostly this went without a hitch, but Rapture Pro threw a couple of wobblies when it would just hang seemingly after installing certain modules. So, instead of selecting "Install All" I did the remaining installs one module/package at a time.
 
This worked, although again installation didn't finalise properly and I had to close & re-open the CCC. The stuck package then showed up as green as in installed properly.
 
So far so good, but there are 2 remaining packages which simply will not install - these are the 2 Legacy packages 1 & 2.
Clicking the install button displays a message at the bottom of the CCC saying "This package did not install properly". Clicking the message to remove it just takes me back to the CCC.
 
So........ 1 - Do I actually need these 2 packages, 2 - what do I do if I DO need them?
 
Thanks all
