Appium failed to create session

Hi,

I am trying to automate Android app. I have installed appium and written sample script to open app in real device. But when i run the script, am getting

“A new session could not be created. (Original error: Command failed: C:\Windows\system32\cmd.exe”… Please help me with this…

Android Version: 10
Appium Version: 1.4.16.1
OS: Windows 7 Home Basic 32 bit

I tried to install Appium latest version. Installed successfully but when i open the app it shows blank page.
