OK. So, I eventully got yotta working on my Windows PC as well as on ubuntu. The steps are:
- Download the latest yotta windows installer.
- Run the installer.
- Click on Run Yotta shortcut on desktop or in start menu to run session with yotta path temporarily pre-pended to system path.
Now, while installing if you are prompted to install python and if you already have python installed, then cancel that part and let the rest of the installation continue. Before running make sure that the path in Environment Variables is correct. Also there will be a Yotta Path and Yotta names in the Environment variables. Befor reinstalling yotta, just delete those two and do a fresh installation.
If this dosent works, try reinstalling yotta and before that install Python 3.5.1 and in yotta installation do not install python 2.7.9.
For ubuntu just follow the steps and it should be done easily.
Hope this helps.
