This issue has been resolved.
Descriptive Problem Summary:
Can't create a stand alone installer with the latest byond version. I think this file is missing as its not in the bin folder and get the message when running the byondexe.exe.

"Unable to write \directx\Jun2010_D3DCompiler_43_x86.cab.
Press any key to continue . . ."
Good catch. This will be fixed in the next build. Apparently I overlooked something when making a change to the build scripts and this file didn't get included in the bin directory. You can grab a copy of it however from your regular BYOND install, as a workaround.
