Do I need previous CVI installations?

[Grant_LECO]

I just installed Labwindows/CVI 8.1.1.  I now have the following directories under C:\Program Files\National Instruments\LabWindows\

CVI71
CVI80
CVI81

I ran CVI81 and it worked fine.  It brought the configuration over from CVI 8.0.1 so I think I'm all set.  I'm pressed for space on my hard drive and
would like to know that it's okay to remove CVI71 and CVI80.

When I Add/Remove programs on National Instruments I see the following programs installed (along with a bunch of others of course )

NI LabWindows/CVI 7.1    FDS Package (can I remove this one?)
NI LabWindows/CVI 8.0.1 FDS Package (can I remove this one?)
NI LabWindows/CVI 8.1.1 FDS Package
NI LabWindows/CVI 8.1.1 Run Time Engine

Can I uninstall the first two without any complications?  I just don't want to mess anything up.

Thanks,

Grant

Every CVI installation is independent from the others, so you should be able to uninstall previous installations of CVI without problems.
