You should do ok if You use the beta of 1.6.
System requirements about the same as with previous versions. You only may need to update the microsoft libs.

https://sourceforge.net/projects/kmeleon/files/k-meleon-dev/1.6.0Beta/K-Meleon1.6.0_Beta2_en-US.exe/download
(dev page
http://sourceforge.net/projects/kmeleon/files/k-meleon-dev/)
Install it in the default folder but a dedicated new folder like:
./program files/K-Meleon1.6.0.Beta2.en-US
Use a User Agent string like
Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.2.26) Gecko/20120128 Firefox/3.6.26 GTB7.1
That way You get a page that is designed for the Mozilla browser family.
