I am on Windows 7 x64, trying to install Python 2.7.5 or 3.3.2. But I'm continuously getting an error showing : "There is a Problem with this windows installer package. A DLL required for this install to complete could not be run. Contact your package vendor. "

I have freshly downloaded the installer package from Python.org for several times but it is giving the same error repeatedly. Please help !

I am also attaching a picture of the error message as it appears while installing.enter image description here

Thank you for your kind concern.!

Yes !!! that did work good.. Thank you very much for this info. but it led me into another Question that why am I not being able to access the installer as administrator while I am logging in as an administrator ? I don't understand ! –  abhisek Jun 30 '13 at 9:05

Go to C:/User/XXX/AppData/Local/temp.
Go to Properties.
Change permission level for everyone to FULL ACCESS.

I think that might work.

ya! it worked for me. But can you explain why does that happened. I am logged in as the administrator but still why ? –  abhisek Jun 30 '13 at 9:19
    
Maybe the installer doesn't have the right privileges? Mind you, the privilege system in Windows is really weird. –  Farid Jun 30 '13 at 9:41
    
yah! i agree too... @Farid –  abhisek Jun 30 '13 at 12:32
    
This didn't work for me though the symptoms were similar. Turned out to be a conflicting PIP install. This fixed me: stackoverflow.com/a/23350061/797945 –  Jagu Dec 16 at 10:21
  • Run cmd.exe (run as administrator)

  • Go to Python's location (example: D:\python\) by changing the directory

  • Write msiexec /i filename.msi, e.g. msiexec /i python-3.4.1.amd64.msi

  • Then Enter
