c++ - Visual Studio wants to load symbols -

so have been using visual studio few years now, when got new computer , installed it keeps wanting things i've never seen need do.

all did make regular win32 console app, following code (really didn't add drastic)

#include "stdafx.h" #include <iostream> using namespace std; int main() {     cin;     return 0; } 

but when went run it, got this

'infpres.exe' (win32): loaded 'c:\users\admin\documents\visual studio 2015\projects\infpres\debug\infpres.exe'. symbols loaded. 'infpres.exe' (win32): loaded 'c:\windows\syswow64\ntdll.dll'. cannot find or open pdb file. 'infpres.exe' (win32): loaded 'c:\windows\syswow64\kernel32.dll'. cannot find or open pdb file.

upon googling, found people extensive projects they've been working on years, , did enable downloading server it's slow , still doesn't work. when does, after it's done download , go run program again throws huge block of error , doesn't run.
