Getting start with PCM

Dear Sir,

I have tried to follow the steps in Windows_howto.rtf to setup PCM.

I have built the pcm.exe successfully and tried to use third party driver, say copy WinRing0* and WinRing0x64* with pcm.exe into c:\windows\system32.

When I tried to execute the pcm -1, it failed to load winring0.dll with error 2.

Would you please advice help can I fix it ? I have copy the result into this post.

Thanks,

Tommy

Error of execution of pcm.exe

the rtf instructs you to copy the drivers both to c:\windows\system32 and the directory with pcm.exe.

Thanks. Actually, I have already copied both pcm.exe and the third party drivers (4 files) to c:\windows\system32.

After that, I executed the pcm.exe and have the error.

Please correct me if I'm wrong.

the drivers must be on your current path. For example

1. Copy all files to c:\pcm

2. chdir c:\pcm

3. pcm.exe
