Followup on l33t's answer above (tried to revise it but it did not seem to appear).

Added later by gpicher 10 Jan 2012: I believe those .msm packages would be for a 9.x version of the DLL in question, not a 10.x version. I resolved a similar problem I had by making a setup project with Visual Studio 2010 installed on a 64 bit Windows installation, using the merge module Microsoft_VC100_DebugCRT_x86.msm in the folder C:\Program Files (x86)\Common Files\Merge Modules. There's a similar x64 version of the .msm if the application showing the error dialog is a 64 bit application. In this case a third party was providing me a debug build of their application in order to develop and test new plugin code against, so I couldn't change build settings, and wanted the debug functionality.
