Program Installation

I have three Partitions on my Main Drive, C: Sys - E: Programs - F: Data.
Some Programs, like Office and HP Printers, Installs default to the C:. There is no apparent way of viewing or changing the Install Drive/Partition.

I have set it this way to make it easier to Image the System and/or the Programs Partitions for Repair requirements.

Can anyone come up with a solution please.

Thank you

Hi Kirsch,
NO! I do not wish to resize the Partition. I want to keep the Sys Partition at about 50GB for WIN 7, Installation, Only.
I have always been used to having the functionality of being able to decide where I want the Installation Files to be Installed.
