Just Installed VS2015, Broken Header Files?
<p>So, I just installed Visual Studio 2015. My OS is Windows 8.1 Embedded (From Dreamspark) and I can't seem to run a simple Hello world program at all without getting errors. (443 to be exact). It's a</p>

<pre><code>Error (active)      the global scope has no "log10l"    Project1    c:\Program Files (x86)\Program Files\VC\include\cmath   675

</code></pre>

<p>My guess is that something might be wrong with the header files, but I reinstalled Visual Studio and that didn't help with anything. Could it be OS related? I'm used to running Visual Studio 2013 on my Laptop w/ Windows 10, but my new computer is running Visual Studio 2015 on Windows 8.1 Embedded from Dreamspark.</p>

<p>Just to make sure, this is the simple code that I'm using to test VS. </p>

<pre><code>#include &lt;iostream&gt;  
int main() {
    std::cout &lt;&lt; "Hello" &lt;&lt; std::endl;
    return 0; 
}
</code></pre>

<p>Hopefully someone will be able to point me towards a solution. Thank you for reading. </p>
