Lol its just for testing yet, but you can use available features
Most important is to select carefully the destination folder for install/replacement and everything is fine.
Try skins too Don´t forget, after installing a skin (or all skins) to select the skin in MTA SA Settings menu, Interface tab, General section the Skins. Usually, the Default skin (or Classic) is selected. After installing (skins) in the list will appear the name(s) of the skin(s). Example: Skin ID 01, Skin ID 02, etc.
Waiting for sugestions!!!
