DLL Load Failed, Not a Valid Win32 App showing for both x86 & x64 DLLs

Trying to run the latest version of heatmap. http://jjguy.com/heatmap/

DLL load keeps crapping out on me in both 64 & 32 bit dlls. (Similar questions on this seemed irrelevant as I've tried loading both DLLs)

I'm running Windows 7. I have uninstalled and re-installed 2.7.3 64 bit.

Idle Top line:

Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on win32

I've tried loading

C:\Python27\DLLs\cHeatmap-x86.dll

ImportError: DLL load failed: %1 is not a valid Win32 application.

C:\Python27\DLLs\cHeatmap-x64.dll

ImportError: DLL load failed: %1 is not a valid Win32 application.

I can run heatmap 1.1 but that was before DLLs were added.

It looks like the DLLs were built with Visual Studio 2012. Do you have it or the VC++ 2012 redist installed? – Peter Huene
Installed & restarted. No effect. – mitrebox
Try to manually load the 64-bit DLL with ctypes.cdll.LoadLibrary. Ignore the 32-bit DLL since you're using 64-bit Python. – Eryk Sun
import ctypes heatmap = ctypes.cdll.LoadLibrary("C:\Python27\DLLs\cHeatmap-x64.dll") Same error. – mitrebox
Did you install vcredist_x64.exe? – Eryk Sun

Do you have this dll? C:\Windows\System32\msvcr110.dll

Copying the dll from another computer fixed the problem for me, not sure how.

Resolved. Blank DLL files were created by the build.bat because the environment variable vcinstalldir is blank if a full version of visual studio isn't installed. DLLs were blank, filesize 0KB

Loaded clean DLLs from github. Filesize 9 & 10kb.

Heatmap library imports & functions as designed.
