In order to download the MSCV71.dll file I recommend you run Dll-Files Fixer. This tool is developed to fix all major .dll related problems. It will automatically download the missing file and it will place it in the proper directory.
Alternatively, in order to fix the missing file issue, open a text editor (Notepad) and paste the following code:
After that save the file as Copy2gac.exe.config and paste it in the Windows Folder > Microsoft.NET > Framework > v1.0.3705 directory.
