[Qgis-user] how best to install qgis 1.6 in windowsXP/vista which already has 1.5?

[M.E.Dodd]

installed 1.5 down the osgeo4w route and now can't find an uninstaller to get rid of it before installing 1.6.  On another machine i had installed 1.6 without removing 1.5 and things got all screwed up so had to manually remove 1.5 (just by deleting folders which is not a good thing to do since it leaves various bits in place elesewhere) and start from scratch downloading 1.6 again.
