I just followed the guide to compile (using Visual Studio) the source and built VW (7.10.1, i.e., the up-to-date version) on my Windows machine. I added the full paths for the locations of **vw.exe** and **vw-hypersearch** to my environment variable PATH. Now if I enter **vw --help** or **vw-hypersearch**, I can get their help message. In fact, the **vw** is working well; I've just used it to train some model and make predictions.\r\n\r\nHowever, when I entered on a command line prompt **vw-hypersearch -L 1e-10 1e-4 vw ... --l2 % ...**, (where the part **vw ...** was the exact command that worked before, just now with the l2 regularization parameter replaced with **%**), I got **command: vw: must start with an executable**. What could possibly be wrong?\r\n\r\nI checked that if I just type **vw-hypersearch**, it does print out the help message, meaning I can call it from the command prompt.\r\n\r\nThanks very much for any help"},"comment":{"url":"https://api.github.com/repos/JohnLangford/vowpal_wabbit/issues/comments/102859163","html_url":"https://github.com/JohnLangford/vowpal_wabbit/issues/616#issuecomment-102859163","issue_url":"https://api.github.com/repos/JohnLangford/vowpal_wabbit/issues/616","id":102859163,"user":{"login":"sharatsc","id":1269880,"avatar_url":"https://avatars.githubusercontent.com/u/1269880?v=3","gravatar_id":"","url":"https://api.github.com/users/sharatsc","html_url":"https://github.com/sharatsc","followers_url":"https://api.github.com/users/sharatsc/followers","following_url":"https://api.github.com/users/sharatsc/following{/other_user}","gists_url":"https://api.github.com/users/sharatsc/gists{/gist_id}","starred_url":"https://api.github.com/users/sharatsc/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/sharatsc/subscriptions","organizations_url":"https://api.github.com/users/sharatsc/orgs","repos_url":"https://api.github.com/users/sharatsc/repos","events_url":"https://api.github.com/users/sharatsc/events{/privacy}","received_events_url":"https://api.github.com/users/sharatsc/received_events","type":"User","site_admin":false},"created_at":"2015-05-17T21:15:56Z","updated_at":"2015-05-17T21:15:56Z","body":"Hi Chia, \r\nDo you mind posting the command line and the error verbatim?\r\n\r\nregards\r\nSharat"}}
