thanks for replying my previous message.
 
as i mentioned in the previous message, the first installation worked fine (more or less), so in order to finish evaluating MonetDB5 regarding  my certain needs, i just want to completely remove it and re-install it.
it looks like that the installation program doesn't completely remove the MonetDB5 installation, so, what's the secrete? how do i (manually) completely remove the installation, so i be able to successfully re-install it as it happened the first time.
 
 
thanks again,
ewilde.
