when I'm installing python 2.7.8 I get error "there is a problem with this windows installer package. a DLL required for this install to complete could not be run". I'm using windows 8.1 64bit

Where did you download the installer from?

How are you running the installer?

Downloaded from official website & I run it by simply double click.  by the
way there is no run as admin

Can you try running this command and then post the log file after installation fails:

> msiexec /l*vx log.txt /i "<path to .MSI>"

I tried but I got this error "this installation package could not be
opened. verify that the package exists & that you can access it, or contact
the application vendor to verify that this is a valid windows installer
package" (screen shot in the attachment)

by the way I'm admin!

You almost certainly have a corrupted download. I'd try downloading the installer again, perhaps with a different browser?

I tried downloading installer by firefox,chrome & explorer with latest
update but still the same problem. I'm getting mad about why I can't get an
error log

I found a fix & this is the source

but the question is did I make a security vulnerability?

Ah, okay, so this is due to the embedded DLL in the installer that we extract and use to validate the install path (if you select a path that already exists, you get a prompt warning you).

I don't know why your %TEMP% directory was not read/write/execute, but since it works fine for most people I suspect a configuration issue on your machine. I have seen in the past some "security" policies that will break installers, though typically launching the installer from an elevated command prompt (one that says "Administrator: Command Prompt" in the title) typically avoids these issues.

Glad you found a workaround at least.

Khalid, when responding by email, please delete the message you are responding to.

Steve, is there any reason to leave this open?  IE, do you plan to change the installer in response to this?

Nope - closed.
