PDremove encounters error

I get this message when running the PDremove utility:
The action "Run AppleScript" encountered an error.
I need to remove all the associated files for Paralles. Is there another method for doing this?

 

Hi, you may do the following:
1. Quit Parallels Desktop
2. Open Terminal (/Applications/Utilities) and execute the following commands one by one

cd Desktop/
mkdir temp_parallels
cd temp_parallels/
curl -O http://kb.parallels.com/Attachments/kcs-35959/PDremove.zip
unzip PDremove.zip
cd PDremove.app/Contents/
sudo chmod 777 PDUninstaller.sh
sudo ./PDUninstaller.sh
rm -rf ~/Desktop/temp_parallels/
sudo rm -rf /Library/Preferences/Parallels
rm -rf ~/Library/Parallels/
rm -rf ~/Library/Preferences/Parallels/
sudo rm /var/root/Library/Preferences/com.parallels.*
