To everyone, I haven't been able to read all of the messages but from skimming them i get the idea you are having issues with the directx9 error, and also a 800 × 600 resolution.
I don't rely on the graphic rule maker as I feel it never quite works for me but I did use it briefly.
To get around the "blocked by admin" issue - this doesn't happen with all dlc, and I think it chooses random ones to block. make a note of which ones get blocked.
1) open task manager and find the option to start a new task
2) click browse and find "autorun.exe" on the disk in your disk drive.
3) tick "run with admin privileges" then click run.
It should bypass the blocking thing. Make note of which games cause this. I have to boot my game through this method because it blocks M&G Stuff and that is what the game launches through
Note: make a backup of any file I ask you to edit
To sort the directx 9 error, in my experience -
1) open graphics rules maker and go to Device Info. There may be two device options. For example, mine shows "Intel graphics" but also "NVIDIA GeForce etc". Pick whichever one brings more power. For me, its the geforce one.
2) take note of what it says next to Device ID for that card. For example 0x34b1. Also take note of what it says in Device
3) You need to get to the video card file in TSData for the version of sims that launches your game. Mine is mansion and garden stuff
Program files 86x > EA games > The sims 2 mansion and garden stuff > TSData > Res > Config > Video cards. Please make a backup of this file
4) Open in notepad and find the family of cards that your graphics card comes from. E.g geforce. At the bottom of that group, add a new entry.
for example "card 0x34b1 "Geforce Rtx 1050"
5) Windows won't allow you to save the file directly back in that location. So save it to your desktop and then move it in and replace it with admin privileges. Also replace the video cards file in CSConfig with this.
I'm going to make multiple posts because my phone is glitching whilst I type this
