unspecified error while installing python 3.5.2 on windows 8.1...can anyone provide how to solve this problem?

Answer 1

You should look on the python site for troubleshooting.
To be honest though 'unspecified error' sounds like something windows would say. So try downloading updates for Windows. Go to PC settings and check for updates. If the service is disabled, reenable it in task manager > services. Make sure module installer is enabled too and then check for updates. Once the updates are installed, try again. If it still doesn't work, then just install a previous version of python until you can get it.
PS: Look up the Universal C Runtime for windows 10 update and see if that helps install 3.5.2.
