How long to uninstall SolidWorks

I have been having problems with Simulation xpress and after a lot of effort by my VAR and solidworks techs. the next step is to remove several versions and sp's of the program and do a clean install after clearing the registry of Solidworks data.

My question is how long does it usualy take to remove the programs?

My control panel is saying I have about 48 Gb of Solidworks on this box.

Our IT is saying  it will take all day.

Can anyone confirm that?
