Hi all,

has anyone successfully installed LAME CODEC on a WIN 11 PC?
My installation doesn't work.

I downloaded the LAME ACM MP3 Codec version 3.99.5 from the known link 
and followed the installation instructions.

Step 3. from the install instruction does not work on WIN 11 PC: cd 
%windir%\SysWOW64
I manually change to the C:\Windows\SysWOW64 directory.

I start the command from step 4.:
rundll32 setupapi.dll,InstallHinfSection DefaultInstall 0 
C:\lame\LameACM.inf

No error comes up, all looks fine, but none CODEC is in Win-Test MP3 
setup available?
Not even after reboot.

Any idea?
