If you are referring to the solution file under lib\csharp it won't build on any
system we have. That was a major concern that we might have a bad system
configuration or install. In the version we downloaded there are no errors in
the unzip process. In the panel under JavaParser items like the JavaLexer.cs,
TokenTypes etc are all incorrect. So we have tried building just the runtime
portion to see if we have a versioning issue. When we do that we get System.Byte
is not defined or imported. We thought about combining files that are missing
from other version but that gets to be problematic even if it works.

We have had no problems compiling and running sample code from the net or books
so it's not an obvious issue.

I agree thats why we used one system running downloaded MSDN components and
another with components from the product CD's (e.g. no association to MSDN).
These aren't even in the same location and different engineers doing the build
with the same results.

See above. I have also been looking at all of the net tools and nothing this
ugly seems to stick out.

I have multiple tools that were all in Java for building analysis tools, source
and runtime, source to source translation and a few other concepts.

We have identical results on a gateway laptop and another running on IBM
Netvista P4's. The netvista is brand new the gateway is a couple of years old.
Both have all of the service packs (as best we can tell with MS) installed both
are running windows 2000.

I agree that this feels like a user Net configuration problem but the chances of
two machines having identical issues has it's own challenge.
