In some cases you may need to manually reinstall/update the Microsoft Visual C++ runtime, which is required for the server to run. The installation attempts to install these automatically, but this seems to fail sometimes (for example missing entry point).
Go to the "Visual C++ Redistributable Packages for Visual Studio 2013" download page: http://www.microsoft.com/en-us/download/details.aspx?id=40784
In most cases you should install both the x64 (64-bit) and the x86 (32-bit) versions. If you're using a 32-bit version of Windows, then you only need to install the x86 version.
When finished, try running Unified Remote Server again.
