[21-03-2018 20:16:59] [5648] ERROR -> Unable to find XML DOCUMENT with path "common\data\dlclist.xml" in archive "C:\Program Files\Rockstar Games\Grand Theft Auto V\mods\update\update.rpf"
I reckon that^ is where you should look first.
Either your 'dlclist.xml' is missing from:
\mods\update\update.rpf\common\data\dlclist.xml
(use OpenIV, go to that location & make sure 'dlclist.xml' exists)
OR
The .oiv installer cannot find it for some reason (not sure why?)
If you don't have a 'dlclist.xml' you can try generating one using Add-On DLCList Generator [.NET] & then installing it (using OpenIV) to:
\mods\update\update.rpf\common\data\dlclist.xml
then retry installing the .oiv
Tip (.oiv Manual Install): If you install 7zip you can right-click an '.oiv' file > '7zip' > 'Extract to "Nameofmodhere\ "' which will extract the .oiv to a folder of the mod name.
In that folder will usually be a 'content' folder & an 'assembly.xml'. The 'assembly.xml' tells the installer what to edit (add lines to 'dlclist.xml' etc (if required)) & where to install the files from the extracted 'content' folder into the game.
You can use this to install just about any .oiv manually. Just go into the 'content' folder, take the files & place them (using OpenIV) in the location stated in the 'archive path' line's in 'assembly.xml'
Example (of the 'archive path' lines format):
<archive path="x64c.rpf" createIfNotExist="True" type="RPF7">
<archive path="levels\gta5\props\vegetation\v_ext_veg.rpf" createIfNotExist="False" type="RPF7">
so for the example above the file 'v_ext_veg.rpf' goes in:
x64c.rpf\levels\gta5\props\vegetation\ ** here **
