Make VS.NET step fails often

[jason_looney]

Within the past week or two, our "Make VS.NET" steps have suddenly started failing about 75% of the time. The error message (see attached) says that two copies of mscoree.dll are in use. I have searched MSDN and Google and haven't found any useful info.

We can build the projects manually using Visual Studio. We have tried removing all older versions of the .NET Framework and explicitly declaring the path to devenv.exe on the Options tab of the make properties.

We are running Visual Build Professional 5.4.

Thanks!
