I have created a GUI on Python 2.7.11 that consists of a main page along with page 1 and page 2 that are linked through buttons on main page. Converted main page to a python exe file using PyInstaller and there were no errors in the conversion. main page.exe appeared in the dist folder but on clicking it, a DOS screen flashed and the main page did not open nor persist on the screen. 
Being a beginner, I am not sure about how to proceed further. Please help.
There were multiple issues associated with converting the Python Script that links modules through button clicks. Keeping in mind these factors, it would be best to convert it to exe using Cx_Freeze. It is more user-friendly and was highly effective for the GUI when compared to PyInstaller and Py2Exe.
