WIth SunBeams permission this is a guide I wrote for another user having trouble getting it to work;
1a) When online in Uplay, select "View Game Details" from the drop down menu that appears on GRW then select "Properties" in Uplay, scroll down and you will find "Game Launch arguments". Click "edit" & add "-eac_launcher".
1b) In Steam do as SunBeam posted in his picture.
2) Make sure you do not have multiple installations of the game, best way is to search your entire PC for "EasyAntiCheat", depending on if you have other games that use it or not will depend on how many folders you will find.
You need to find ALL "EasyAntiCheat" folders that are within "Tom Clancy's Ghost Recon Wildlands".
For me I have one on D: & one on E:. In every folder over-write the "EasyAntiCheat_x64.dll" with the downloaded one (15kb), linked on page 11 of the thread I think.
3) Find GRW.exe, make a NEW shortcut from this on your desktop. Add the -eac_launcher to the end of the "target" line as well.
4) Not sure if this step is needed, but I did it to make sure I do not accidentally go online in any way - I disabled my network adapter, perhaps killing all traffic via a firewall or just putting Uplay into offline mode would be enough, I did not take the risk.
Since then have not done this & it still works, but if you having issues why make it more complicated?
5) Run the game with the NEW GRW.exe shortcut.
6) When at the main menu, launch Cheat engine 6.7 x64 attach it to the GRW.exe process & load table, DO NOT ACTIVATE IT YET. N.B. If you see "EasyAntiCheat" as a process in the process list on Cheat Engine when your attaching it to GRW.exe then EasyAntiCheat is successfully running and you have missed a .dll
6b) At this point you can attempt to search for the string "ChangeList" as per the original post by SunBeam in the thread, if you can search and do not get an access violation or other error likely means that it has worked.
7) Load the game, run around a bit, then activate the "Gather Intel" script in CE. That should get it all working.
Other items of note;
If your having issues it might be worth making sure your .exe's are running with admin rights enabled.
If your having access violation issues check your permissions, message me back with your windows version & I shall find the correct info for you
It may be worth disabling your AV when moving the .dll file around as some av's are sensitive to it.
All praise be to SunBeam, the creator of the table
