Q:

Visual Studio 2005 - C++ - What controls the manifest creation

I was trying to figure out why a debug build was blowing up with the "dependent assembly microsoft.vc80.debugcrt could not be found" event error.
After deleting everything (anything not .cpp or .h) and recreating the solution - I still had the problem.
A google search was fruitless and a re-install of VS didn't produce any change.
I did have the dlls in C:\WINDOWS\WinSxS\x86_Microsoft.VC80.DebugCRT_1fc8b3b9a1e18e3b_8.0.50727.42_x-ww_f75eb16c.
I opened the \debug\.exe.intermediate.manifest file and it had 2 (dependentAssembly) entries:
    1st: name='Microsoft.VC80.DebugCRT' version='8.0.50608.0'
    2nd: name='Microsoft.VC80.DebugCRT' version='8.0.50727.762'   
If I delete one and change the other one to
 name='Microsoft.VC80.DebugCRT' version='8.0.50727.42'
I can get a build that will start.
Granted I did have VS2008 installed - but what is controlling the versions ? or How can I get the right debug dll version to "stick".
VS2008 was de-installed through the control panel.
EDIT: Found nothing in the registry if DebugCRT is searched for.
      the environment path points to the VS8 folders .
      There is only 1 DebugCRT folder in the c:\windows\winsxs\policies folder
         (8.0.50.727.42)
      The c:\windows\winsxs\manifests folder only has the .42 version of .cat and .manifest
      The .manifest file (in above manifest folder) has version="8.0.50727.42"  
Clarification: the manifest file has 2 "dependentAssembly" entries each with different versions and not the .42.  I can delete 1 entry and change the version on the other to match the .42 to get a debug build that starts.
EDIT2:I'm also using boost and inside the DLLs there is the .762 version

A:

The version was picked up by from the Boost DLLs which were a download, pre-compiled version of Boost.  Once the libraries were re-compiled (and re-installed) a re-build of the solution produced a manifest with a single version and the program linked and ran.
So -Check the libs and dlls that are imported into the solution for version used.
