No, post some screenshots as the mod pack Engrel.exe in the new PRG_Eng folder already has the no cd fix within it. So sounds like you are not using it. All this is why I simply offer to remote in via Teamviewer which is 100% secure and I've helped thousands of fans over decades, to save my own time and theirs, when they struggle to follow 5 steps.
Since it doesn't mention downloading the .dll that you are doing in your first screenshot and also doesn't include using the texture switcher or no cd.
Your screenshots don't show that you have used the mod pack, plus it states to use dgvoodoo version 2.6.3.
Did you try the registry fix in the guide and also download dgvoodoo2 which fixes this issue. Post screenshots to confirm each of the 5 steps of the guide have been followed. Plus evidence that your dgvoodoo2 settings are correct.
Hi and welcome, probably easier for me to remote in via Teamviewer and diagnose each step of the guide. Message me your Teamviewer ID and a suitable time.
Hi, follow the help fix guide as it shows you what to do if the setup.exe doesn't run. Once you have that working then the mod pack replacement Engrel.exe doesn't require the CD.
