Hi Experts,<br />
<br />
I'm using VS 2013.<br />
<br />
I've got this VB.NET Windows form (attached).<br />
<br />
When I double click on it's name in Solution Explorer only the source code opens, not the Designer.<br />
<br />
That form was working OK a few days ago.<br />

Microsoft Visual C++ (often abbreviated as MSVC or VC++) is an integrated development environment (IDE) product from Microsoft for the C, C++, and C++/CLI programming languages.

Many applications require redistributable Visual C++ packages to function correctly and are often installed independently of applications, allowing multiple applications to make use of the package while only having to install it once
