how to remove rpm installation?
 

I just installed it and "rpm -e" protests the package doesn't exist.
Any ideas?
Thanks

try

rpm -qa | grep PACKAGE_NAME

then rpm -e whatever the above returned, its probably somthing like it doesn't want the package version

also, when using rpm -e command, you have to put only the name of the package, without .ix86.rpm or whatever extension it has.
