How do you correct the error 'the procedure entry point dot3queryguidncsstate could ot be located in the dynamic link library dot3apidll'?

Answer 1

First, I'd try scanning with the system file checker.

Go to start -> type in cmd. Right click on the cmd.exe result and hit 'Run as Administrator'. Type sfc /scannow and the windows system file checker will scan all important windows files, including most dlls. If it detects and error, restart your computer. Then, try starting AoE3 again.

Next, You might try registering the dll. (Though I don't think this will work; the error sounds like it's loading the dll but has an issue once it gets it loaded.)

First, go to start -> type in cmd. Right click on the cmd.exe result and hit 'Run as Administrator'.

If you are using the 64-bit version, type this and hit enter:

SysWoW64regsvr32.exeSysWoW64dot3api.dll

Otherwise try just entering:

regsvr32.exe dot3api.dll

You may have to fully qualify the path of the .dll file.
