Error with IIS app pool, compstat.dll failed to load

So I go this message

The Module DLL C:\Windows\System32\inetsrv\compstat.dll failed to load.  The data is the error.

When trying to start up application pool. I have a shared configuration between servers, the server that got the error didn't have static compression installed so it couldn't start. Even though I had disabled compression. 

The way I figured it out is because of this page http://learn.iis.net/page.aspx/101/introduction-to-iis-7-architecture/ where it says that this module is for static compression
