Mmk, so Windows can't find java.exe. Your batch file is fine, and is in the same directory, Win7 64-bit shouldn't make a difference, I'm running the same thing. Good that Java is up to date, but not necessary (I don't think?). Hmmm... Alright, here we go: 1. Remove '\java.exe' from the path name you added to the PATH variable and try again. It's supposed to be a path to a folder, not a file. Still doesn't work? Next step. 2. Check the location you added to the PATH variable. Are you sure that's exactly where your java.exe file is stored? I know that in mine (also Win7 64-bit), there's another folder under 'java' called something like 'java6' (I need to re-check). Not working? One more step. 3. Make sure you've separated the entries in the PATH variable by semicolons. If this doesn't work, post your entire PATH variable. Yes, all of it. There may be an error in there you need to correct for it to parse right.
