Is it possible to make a single file executable as an install?
Visual Studio Gallery only allows you to update .vsix, .exe or .msi files, but the ones created with the InstallShield Limited Edition (for Visual Studio 2012) creates the .exe and .msi, but they do not install without all of the files in the same directory (program files\[company]\App) and some other files.
I believe you can create a single exe or msi file by creating a compressed release. This option is in Build tab under releases view. If you want single exe, enable setup launcher to Yes which is under setup.exe and if you want single msi file disable this option.
