Thanks that's much clearer now. Could you please Confirm the missing dll is exactly "cygboost_thread-net-1_43.dll" Go to PriiDash - Browse Files at SourceForge.net and download the previous version, 20110726 (the directory said 20110627) version, and run the precompiled file as you did. I am still puzzled why it would be looking for a dll. I thought the precompiled executable are self contained with all libraries compiled in statically. I could be wrong though. Sorry this is causing so much trouble. Hope we will get it working soon.
