timedate.EXE does not exist in a normal Windows 7 system.
You want timedate.CPL which is located at C:\Windows\System32\timedate.cpl
What exactly did you do that caused the following error?
C:\Windows\system32\rundlll32.exe:
Windows cannot access to specific device, path or file. You may not have the appropriate permission to access the item.
You should not be running two antimalware programs. I suggest uninstalling or at least disabling 360 total security (Free).
Is "Activation winse7en" some sort of crack for Windows 7? Do you have a valid Windows 7 Product Key (do not post Product Keys here).
