Thank you all for the replys to my enquiry. I solved my problem by installing the Service Pack 1 of VC-8.0. This update introduces a new set of runtimes (rev 762) that the loader is able to match with the Boost dlls. Oddly enough, the dependency walker (V2.2.6000) still fails to locate MSVCR80D.DLL as referenced by the version of MSVCP80D.DLL located here: c:\windows\winsxs\x86_microsoft.vc80.debugcrt_1fc8b3b9a1e18e3b_8.0.50727 .762_x-ww_5490cd9f\MSVCP80D.DLL Best regards, Charles

My boost dependent applications fail to start in debug mode: error 14001. The dependency walker cannot locate the VC-8.0 runtime dlls referenced by the boost-*-vc80-mt-gd-1_34_1.dll libraries I build on my machine. That is the multi-threaded debug dll runtime: MSVCP80D.DLL, MSVCR80D.DLL. The binary distribution I got from boost.com has the same problem. This is related to the side-by-side configuration rather than making sure that the runtime dlls are in my path. A default win32 console project from VC-8.0 links fine in multi-threaded debug dll runtime mode. Also, a dll compiled in the VC-8.0 IDE referencing boost will resolve the runtime correctly but the associated boost dlls won't. Thus the dependency walker will also report unresolved runtime dlls/

I have re-installed VC-8.0 but without success. I also have VC-7.1 on my machine.

Help is greatly appreciated.

Best regards, Charles
