I have downloaded the latest WPI but I get some wiered results when running my test app. When I run it from the desktop, %temp%, %systemdrive% it gives the error: command 1 failed. I have tried with running as admin as well as folders without spaces and with spaces, all gives the same result. But if I run the same thing inside %programfiles% it will work and have success on install. I have tried on windows 7 x64, x32 and xp same result. Is there a way to make the WPI work from any folder?
