Please report any bugs or feature requests in the forums.
Is Process Hacker a portable application?

No. Please read about the other definition of "hacker".

Symbols don't work properly!
Firstly, you need the latest dbghelp.dll version:

1) Install the latest Windows SDK (links are below).
2) Open Process Hacker options via the main menu: Hacker > Options
3) Click Symbols, and locate dbghelp.dll
Windows XP, Vista and Windows 7 SDK:
C:\Program Files\Debugging Tools for Windows (x86)\

Windows 8 or above SDK:
32bit: C:\Program Files (x86)\Windows Kits\8.x\Debuggers\x86\
64bit: C:\Program Files (x86)\Windows Kits\8.x\Debuggers\x64\
Secondly, you need to configure the search path. If you don't know what to do, enter:
SRV*SOME_FOLDER*http://msdl.microsoft.com/download/symbols

Replace SOME_FOLDER with any folder you can write to, like D:\Symbols. Now you can restart Process Hacker and see full symbols.
Why can't I build Process Hacker?
The most likely problem is that you do not have the latest Windows SDK installed.
Download: Windows 10 SDK
