But as fare as i remember ActivePerl installs normally in C:\Perl. All the stuff should be gone if deleting this folder... and that is what he did.
"Normally" perhaps yes, but if all went "normally" she would not have experienced these problems.
And I am not too sure everything is in "C:\Perl" (or whichever folder you choose at install-time). AS Perl does things to your Windows registry as well, your paths and file-associations and perhaps even adds things to your "Documents and Settings".
Recently I had some problems with my AS Komodo IDE. Uninstalling and re-installing did not solve the problem, until I saw that "Documents and Settings" had several "Komodo" folders, which were not deleted by the uninstall. I deleted them manually and re-installed and now everything works again. Maybe AS Perl saves some settings in these folders as well.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
