Hello, I tried running prefast on the example toaster code and it wouldn't run. I was running under the 2003 IA-64 environment and prefast was not in the path. I then added it to the path and ran prefast build -ce. I get the following error. PREfast did not appear to do anything. If there was no error on your command line, it may be that your build command is overriding PREfast's settings. The prior result log was retained. I also noticed staticdv was not in the path Any ideas? Are these known bugs ? I got prefast to work on DDK 3790.1830 under the IA64 environment, my next step is to try the prefast from the 3790.1830 build. thanks Mel
