Unable to read SAV files on Windows10

[Former user]

I was using the package to read an sav file on Windows 8 and it worked fine, but I updated to Windows 10 recently and am unable to use the package to read in files. I'm relatively new to Python, so I am unable to understand what's causing this error. Here's the traceback I get when I'm trying to read a file in.

TypeError: bad argument type for built-in operation

Hi,

I think you need to upgrade to the latest version. This is probably due to the fact that ctypes.util.find_library('c') returns None in modern Windows versions (https://bugs.python.org/issue23606), which then causes a TypeError in the next step. What output do you get if you run this in a command prompt?

python.exe -c "import ctypes.util; print(repr(ctypes.util.find_library('c')))"

Best wishes, Albert-Jan

Hi Albert,

The output I get is 'None' when I try that in command prompt. I am using the latest version of the package (3.4.2). Here's my Python version:

3.6.1 |Anaconda 4.4.0 (64-bit)| (default, May 11 2017, 13:25:24) [MSC v.1900 64 bit (AMD64)]

Could you please let me know if I should upgrade any other packages?

Thanks!
