Updating Imagemagick

Hi,
I currently have Razuna 1.4.7 running on Windows 2008 R2 Standard and am starting to update the various 3rd party programs needed for newer Razuna versions and have a question regarding installing a new version of Imagemagick. The current version is located in C:\ImageMagick-6.7.7-Q16. Do I need to uninstall that first before I install the newest version of Imagemagick? Their site says I can have numerous versions installed on the same server but was curious what others do?
Thanks

If you run the IM installer it even says that you should first uninstall
the old version. I always just have one version, thus I uninstall first.

Thanks, It’s nice to know for sure. I’ve got all the 3rd party programs installed and my 1.4.7 still works so now I guess I’ll start to focus on working through the versions.
