Hi Ankit, You can uninstall and reinstall with internet on and install as administrator. If the problem persists do the following. For unable to open Osdag: Can you open command prompt in osdag folder and type in "python"? It should give you python version. installation location etc. If you get python version details as 3.* then you can type in... "python osdagMainPage.py" and press enter. Osdag will open. If it doesn't then you should add python path in your environmental it is which is "miniconda3\Library\bin" and "miniconda3\Scripts" (please make sure you enter full path you will find miniconda3 in osdag folder or programs32) and then do the above step. For Latex issue: open command prompt in osdag folder and type "latex". If it gives you version number and other details if means it is properly installed. Else you have to find where latex is installed and add it to your path. To add paths to your environmental variables you can just search for environmental varaibles in windows search bar. Please keep us posted.
