All ITs passed on my box. I ran mvn clean install -Prun-its -Dnpanday.version=1.2-RC4.
I was able to successfully ran the installer but I have to manually add the uac/gac_msil folder in my local repository.
For the repository builder, I got this error when running the vsinstaller command after extracting the builder in my local repository --> http://pastie.org/1001561
I was able to successfully ran NPanday in VS after building the tag then ran the vsinstaller command.
