Hint: use ‘@foo’ to launch a virtual device named ‘foo’.

invalid command-line parameter: Files.
Hint: use '@foo' to launch a virtual device named 'foo'.

If you’re trying to use eclipse to build an application, like me, then you have probably ran in to the above error when using Windows 7 64bit with 64bit Java.

I have tried a LOT of different solutions but none worked. So while reading about creating a symbolic link in windows I came up with an idea. COPY THE ANDROID FOLDER LOCATED IN YOUR Program Files (x86) FOLDER TO C:\ANDROID. Once it’s finished change the link in Eclipse (window / preferences) to the new location.

All I know is it’s working fine for me now and I HOPE this helps someone else out!

      3. Scroll down to Additional Emulator Command Line Options and put in: “-scale 0.8” or another number .
