SCCM PatchDownloader.log Path. I get some errors with updates downloaded and need to watch logs for errors. In google, you will find many paths for SCCM 2007, 2012, and 2012 R2 where find PatchDownloader.log and other logs.
Where to find logs in this version:
%WINDIR%\System32\CCM\Logs
%WINDIR%\SysWOW64\CCM\Logs
In my case they host in the next folder:
C:\Program Files\SMS_CCM\Logs
