When I try to install any extension for visual studio ultimate 2012 on my new installation of Winodws 8 I get this exception :
System.IO.FileNotFoundException: The system cannot find the file specified. (Exception from HRESULT: 0x80070002) at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at Microsoft.VisualStudio.Settings.ExternalSettingsManager.GetScopePaths(String applicationPath, String suffixOrName, String vsVersion, Boolean isLogged, Boolean isForIsolatedApplication) at Microsoft.VisualStudio.Settings.ExternalSettingsManager.CreateForApplication(String applicationPath) at VSIXInstaller.App.GetExtensionManager(SupportedVSSKU sku) at VSIXInstaller.App.GetExtensionManagerForApplicableSKU(SupportedVSSKU supportedSKU, IInstallableExtension installableExtension, List`1 applicableSKUs) at VSIXInstaller.App.InitializeInstall() at System.Threading.Tasks.Task.InnerInvoke() at System.Threading.Tasks.Task.Execute()
I tryed to repair VS, did not work, and also try to uninstall/install and got the same problem. Anybody as an idea?
I was stumped by this until I realized that I had somehow deleted my My Documents directory. Recreating
C:\Users\<username>\Documents allowed it to install.
Others have reported the same bug when My Documents has been remapped to a different location. The workaround is to map it back to the standard location, install the
vsix, and reestore your mapping.
If all else fails, you can manually unpack the extension:
.vsixfile as a subdirectory of the Visual Studio extensions directory
C:\Users\<username>\AppData\Local\Microsoft\VisualStudio\11\Extensions\, alongside the extension you installed (I used 7-zip).
