hey everyone. i have some freakin problem there. i used to have sparkiv before and gta 4 installed via steam, but then i took a copy of game content, and deleted gta 4 from steam. i always use this copy content for gta 4 to play with enb, so i dont have gta4 in steam folder.
thats the point that problem starts! i cant use spark iv, since i deleted gta 4 from steam. i tried to install openiv, and tried to open /vehicles/models and this error shown

even i choosed the true gamepath. i dont want to install whole game for using this sparkiv or openiv. can anyone help me with this?
i will be very pleased.
thanks
