Use BlueG's SQL. They are fast and well optimized. XAMPP and WAMP are both packages which contain web servers and back end servers etc. Both works same. if StrickenKid is not working on XAMPP may be you had not correctly configured the script.

latest SQL by BlueG should be R41-4[https://github.com/pBlueG/SA-MP-MySQL/releases].
R7 is way too old.
