Upgrading to NIs 2010

Hi,

 

I am thinking of upgrading to NIs 2010 on my computer.  I have nis 2009 on my computer right now.  I know some people are having problems with upgrading to NIS 2010.  Can you remove NIs 2009 with add remove programs on windows xp. Then can you install Nis 2010.

 

Thanks

 

P.S Are people having a lot of problems when there are install Nis 2010 over Nis 2009.
