Problem Installing Lookout 6.1 After Install/Un​install Lookout 6.5

Question

I'm getting the message "You have a higher version of NI Uninstaller in your system" when I was trying to re-install Lookout 6.1 after installing and uninstalling Lookout 6.5.
The error says for me to uninstall the higher version of NI Uninstaller?  Where and how do I do this?
Thanks,
Max

I'm running Windows 7 Professional (64 bit)
1) This is the error I get when installing Lookout 6.5
I then select "Yes" to continue, choose "evaluation mode" and let it complete the install, restart computer and run Lookout 6.5.
But Lookout 6.5 does not run and I get the following error:
2) Now I try and install Lookout 6.1,  the part where it is initializing the installer completes and I click on "Next"
    I go through with the information input for user/company/serial, select complete install, license agreement and then click next and I get the following error:
And now I am at the problem.
So I click on Yes (to continue) and I get the following error:
and I continue and get the next error
and so on...
Thanks for your help.  I'm almost short of formattimg the drive and reinstalling the entire system but I'm hoping it's just a minor item that was overlooked.
