There are still some FivePD severs. But they are on the decline 

you need open iv ok
 

go to your asi manager and make sure you have asi loader and openIV.asi  

now in your mod folder for openiv make sure you have update,  x64 , and common.rpf in order to install the dlc you need to go to update -> x64-> dlcpacks drag and drop the  sheriffpack or sheriff pack blue into the dlc pack folder 
Always rememeber those readme.txt are gonna be your bestfriend this came from the read me file for the sheriff pack
 
1. Drag the SheriffPack AND/OR SheriffPackBlue folders into your mods/update/x64/dlcpacks folder.
2. Navigate to mods/update/update.rpf/common/data and edit dlclist.xml.
3. Copy this below into your dlclist.xml file, save and close.
      <Item>dlcpacks:/SheriffPack/</Item>
      <Item>dlcpacks:/SheriffPackBlue/</Item>
4. Copy ELS files into your ELS/pack_default folder.
