LyXWinInstaller 1.5.2 error, Removing old version

[Dave Hewitt]

(Uwe, I'm posting to the list because I thought others might be curious as 
well.)

I used Uwe's LyXWinInstaller Update to upgrade to 1.5.2 on WinXP, but 
encountered the advertised problem with ImageMagick. Uwe indicated (to the 
list as well, I believe) that all we need to do is uninstall LyX 1.5.1 and 
then use his small installer for 1.5.2 to get ImageMagick back and working 
properly. When I run the uninstall program I get a window that asks whether 
I want to remove the LyX User Preferences as well (the LyX program is 
grayed out b/c you can't opt not to uninstall that, obviously). Does anyone 
know whether I need to remove the User Preferences in order for the 1.5.2 
install to work properly (i.e., fix ImageMagick)? I don't really know 
what's included in the Preferences, but I made some changes to defaults and 
would prefer not to lose that if I don't have to.

Thanks,
Dave Hewitt
