Bob,<br /><br />Glad to hear it is working for you.&nbsp; A few questions just to make sure something wasn't missed.&nbsp;&nbsp;<br /><br />Did you build edk2 base tools using the process here.&nbsp;<br /><a href="https://github.com/out0xb2/edk2/blob/feature/pytoolsForOvmf/OvmfPkg/README-pytools.md#differences-from-edk-classic-build-setup">https://github.com/out0xb2/edk2/blob/feature/pytoolsForOvmf/OvmfPkg/README-pytools.md#differences-from-edk-classic-build-setup</a><br /><br />If you follow the process documented it puts a file in the output folder that will trigger pytools to add the folder to the path and set an environment variable as required by edk2 build.&nbsp;&nbsp;<br /><br />If you build the basetools yourself please delete them and use the process above.&nbsp; After doing that you should not need to add basetools/bin/win32 to your path.&nbsp;&nbsp;<br /><br />Please let me know if that doesn't work.&nbsp;<br /><br />Thanks<br />Sean<br /><br />
