Hi Everyone!!

If Caesar IV won't run and you have tried every possible solution mentioned everywhere (adding dlls, disabling UAC, administrator mode, compatibility mode, installing C++, every directx, frameworks, runtimes, etc.), then maybe this post will help you.

Go to the web page mentioned below and download Dependency Walker, the 86x version (doesn't matter if you have a 64x machine, this is because Caesar is an 86x program).

https://www.dependencywalker.com/



Once downloaded, unzip the files an run the executable called "depends.exe". Once it's open, click on the folder icon and search for the Caesar IV executable which should be on the path mentioned below (unless you have specified a different path when you installed it):

C:\Program Files (x86)\Steam\steamapps\common\Caesar 4\C4





Once located, double click on the file and let the program run. When it's done an error message will appear, it's ok, ignore it and press ok. Now, there will be a list below in the "Module" section, right click on any row from this section and click on the "Full Path" option. Now start going down in the list until you reach the rows that are shown with paths (ex. c:\windows\system32\....).



Once you're here, start looking at every row which in the "CPU" column says x64 in red color. Shouldn't be too many, in my case it was just one file (c:\windows\system32\D3DX9_29.DLL). This means that there's a file that the game is trying to use (the 64x one you just found) but its not from the same architecture as the game (86x), which causes the problem. If you find a row with x64 in red, what you need to do is:

- Look at the name of the DLL file and copy it's name
- Search and download this DLL, it's very important that the version that you download is x86 and not x64. I recommend the following web site: https://www.dll-files.com/
- Once downloaded, go to c:\windows\SysWOW64, make a backup of the file you're going to replace, and paste the downloaded DLL here (despite that Dependency Walker says that the path should be c:\windows\system32, use the path mentioned previously or the fix won't work).
- Rinse and repeat for every other row you find with CPU marked in red stating x64.











Once you're done, you should be able to start the game even from the Steam launcher. As I said previously, in my case I had only one row with this problem. I downloaded the 86x version of D3DX9_29.DLL and pasted it in the SysWOW64 and the problem was gone.

No other solution worked for me except for this. I hope this will fix your game like it did to me, I'm happy I can play this game again!!

Regards!!
