Trying to install Python 3.4.3 64-Bit and it gives me the following error: 'There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support or package vendor' I have no bloody idea what this means so please help. Thanks in advance I'm the admin on my computer and have all permissions My windows is 64bit and is Windows 8.1
pip is the preferred installer program. Starting with Python 3.4, it is included by default with the Python binary installers. A virtual environment is a semi-isolated Python environment that allows packages to be installed for use by a particular application, rather than being installed system wide.
I had the same phenomenon occur when trying to clean up (uninstall various versions of Python and perform a clean install of 3.4.3) on my Windows 7 64-bit laptop. Unfortunately, I cannot tell you what "program required for this install to complete could not be run". Repeated attempts to "install for all users" produced the same "could not be run" (followed by a roll back of the install). Just before getting out Orca and diving into the innards of the MSI file, I attempted an "install just for me", and the install completed. I am, in fact, the only (human) user of this computer. There is another user account that was created during a cygwin setup, and access to some aspect of that user's profile/resources may have been the issue. If you are installing Python for your own use - and not as a "platform-wide" resource for other users as well - you might try installing "just for me".
