Often the MP3 encoder is also needed to import media files into certain applications like Camtasia Studio. This is also the case when you receive the error message “no codec available to render this file” when you’re importing a MP3 file into Camtasia Studio.

1. Step Download Lame from sourceforge (latest may 2010: 3.98.4)

2. Step Extract all files inside the zip archive to C:\lame

3. Step Open an elevated command prompt

4. Step Type cd %windir%\SysWOW64 and hit enter

5. Step Next, type rundll32 setupapi.dll,InstallHinfSection DefaultInstall 0 C:\lame\LameACM.inf to install Lame via the LameACM.inf file.

Lame for Audacity

If you are still receiving the error “no codec available to render this file” when you are importing MP3 files in Camtasia Studio, simply use Audacity to re-save the MP3 file. Install Lame for Audacity and then import the MP3 file and export again as MP3.

    @almost everyone — “installation failed” — that’s because the instructions are old, I think. The path in the command prompt–you need to enter C:\lame\ACM\LameACM.inf rather than just C:\lame\LameACM.inf

    All that said, as much as that did sort the installation failed error, it prompts me for “lameacm.acm,” which doesn’t exist. .def and .inf do, but not .acm.

    Lame 3.99.5 Windows 7 64-bit install failed Am thinking that ACM.inf does not exist even in ACM subfolder within “lame” folder on the C drive. There are ACM.cpp and ACMD.h and acm.rc files. Googling–> the first two files are C++ related. The dot h file is a Windows configuration file. Should I direct my command line install instructions to that file? That is lame-3.99.5.tar.gz download from SourceForge extracted twice using 7-Zip until all files from lame-3.99.5 are in C:\lame, as instructed, on Win7-64.
