Problem in launching upload tool in ODK Aggregate

What is the problem? Please be detailed.

I tried to install the ODK aggregate but once I have provided the application id, username and then reached the stage to launch the upload tool, when I pressed the finish button, I got an error message and then the process gets terminated. Please suggest how to solve this.

What ODK tool and version are you using? And on what device and operating system version?
I am using ODK Aggregate v1.7.1 Windows.exe

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.
