error HRESULT: 0×80070057 (E_INVALIDARG) [SOLVED]

If your computer dies or crashes during shadow-copy stage of .net framework files, you’re in trouble. The specific error is “Exception from HRESULT: 0×80070057 (E_INVALIDARG)”.

To fix it, you need to get rid of the files that were corrupted during the interrupted file copy:

• Find the .NET framework complilation folder (in my case it was: “C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files”)
• You also might find it on Framework64, or another version (v2, v3) folders... that haves temporary ASP.NET files.
• Delete all folders other than “root”
• Open up the “root” folder and delete all subfolders
• Pull your website up in the browser
• It should compile successfully and load the website.
