I am trying to install Visual Studio 2012 Express for Windows Desktop and get the following errors:
Setup Engine - Access is denied.
Microsoft Visual C++ 2012 x64 Additional Runtime - 11.0.50; User cancelled installation
I have given my profile every single Admin permission possible. I have even tried this directly on my Administrator account and the same errors come up. I have also tried installing SQL Server 2012 manually and downloaded the SubInACL program.
From your post, I think this issue related to the UAC. I guess that your current account have not the full permission of Administrator. Please disable your Anti Virus software and
re-install the Visual Studio as the administrator.
