Cancel that. I guess I finally got it, and it started to compile and getting along further. I have now been dealing with : LINK : fatal error LNK1181: cannot open input file '..\..\lib\libpjproject-i386-win32-vc8-release.lib' All the references are in the "libpjproject" as I had before in VC++ Express, and compared them to make sure. Thank you for the response.

C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Lib\x86\dsound.lib On Fri, May 25, 2012 at 3:35 PM, Trent Creekmore <tcreek at gmail.com> wrote: Just put back on VS2008 Professional and removed the Express Edition and now I am getting this error after the changeover. The path to Direct X SDK(June 2010) (\Lib\x86) is still there in the project "libpjproject." Looking at that directory, I see the file is there. I also went into Tools-> options -> Projects and Solutions-> VC++ Directories and added the various DirectX directories into there. Executables (\Utilities\bin\x86) Include (\Include) Lib (Lib\x86) What did I miss?
