Debugging Installation Problems with Visual Studio 2013 Express for Web

I'm having 2 strange issues on a fresh install of VS2013 Express for Web. The install seemed to go ok, but when completed I have two problems.

Could anybody help or point me in the right direction to either solve or begin debugging this? I am praying against a Windows reinstall, but it's starting to look like the only option.

1. Can't Create New Project or New Website

A new project gives me this alert box:

Error loading type library/dll.  
Exception from hresult: 0x80029c4A TYPE_E_CANTLOADLIBRARY

When attempting a new Web Site, it gives me:

Exception has been thrown by the target of an invocation.

2. No exe File in Start Menu

I don't know if it's related or not, I'm hoping it's a clue.

There is no exe in the start menu. There's a VS 2013 folder, but it's empty.

What I've Tried - Updated

• Uninstalling / reinstalling (many times!)

• Installing through WebPI and through direct download from website

• Applying updates from Windows Update

• Then uninstalling and reinstalling again

• Ensured system path is under 2000 chars (it's 600)

• Disabling anti virus when installing

• Ensured .NET Framework is up to date on PC

• Running VS as Administrator

• Installing VS as Administrator

None of these steps seemed to help - all gave me the same result.

Google results for the error messages mostly refer to different circumstances - e.g. somebody trying to integrate a VS app with MS Office.

Final Update

I ended up reinstalling Windows - that worked.
