I am running out off space on the C: Drive where my OS Win7 is installed. I am planning on using the Acronis backup and restore to move from thus 120GB to a larger 225GB SSD next weekend.

 

My P3DV3.2 is installed in another HD (Drive P:\p3dV3\)

 

Do I have to to uninstall the P3D client and then reinstall and reactivate after my OS drive move? or is this unnecessary?

As long as the drive letters remain the same, you should be fine.
