Hello,
what kind of error do you get?
Environment variables you can set this way: Go to KuneriLite folder, see the start.cmd:
It should have PERL, CLS Arm Toolchain and Symbian paths as you have installed them, like :
@SET PATH=%PATH%;C:\Program Files\CSL Arm Toolchain\bin;C:\Program Files\Common Files\Symbian\Tools;c:\perl\bin;\Symbian\
then also devices set command :
devices -setdefault @S60_3rd_MR:com.nokia.s60
and also EPOCROOT path :
SET EPOCROOT=\Symbian\9.1\S60_3rd_MR\
You many need to apply Vista patch too :
