System.ComponentModel.Win32Exception when starting process - file not found, but file exists
Clearly you are using a 64-bit version of Windows. The c:\windows\system32 and c:\program files directories are subject to a feature called "file system redirection". It is an appcompat feature, it helps to ensure that 32-bit processes don't try to use 64-bit executables. They'll get redirected to c:\windows\syswow64 and c:\program files (x86).
So when you try to start a file in c:\program files\realtek\etcetera, your 32-bit program will be redirected to c:\program files (x86)\realtek\etcetera. A directory that doesn't exist, kaboom. Same ingredient for igfxtray.exe
You'll need to change your program's platform target so it can run as a native 64-bit process and avoid the redirection problem you now have. Project + Properties, Build tab, change the "Platform target" setting to AnyCPU.

I am trying to create a manager for my autostarts. It should read an XML file and then start my programs with a custom delay. For example:
<startup id="0"> <name>Realtek Audio Manager</name> <process arguments="-s">C:\Program Files\Realtek\Audio\HDA\RtkNGUI64.exe</process> <delay>5</delay> </startup>
This runs the specified process (
C:\Program Files\...\RtkNGUI64.exe -s
) after 5 seconds.Now, three of the programs won't start, giving me a
System.ComponentModel.Win32Exception
: "Das System kann die angegebene Datei nicht finden." ("The system was not able to find the specified file.")But the XML is parsed correctly, and the file I want to start is at the location I specified in the XML file.
The problem concerns only these three files:
Intel HotkeysCmd - C:\Windows\System32\hkcmd.exe
Intel GFX Tray - C:\Windows\System32\igfxtray.exe
Intel Persistance - C:\Windows\System32\igfxpers.exeI think that the problem comes from the location of the files: they all are located in C:\Windows\System32, and all the other, working programs are located outside (C:\Program Files, C:\Program Files (x86), D:\Program Files,
%AppData%
)Do I have to give my program some kind of access rights to start programs in C:\Windows\System32? How would I do that?
If not, what could be the reason I get errors with these programs?
EDIT - my code:
delegate(object o) { var s = (Startup) o; var p = new System.Diagnostics.Process { StartInfo = new System.Diagnostics.ProcessStartInfo(s.Process, s.Arguments) }; try { s.Process = @"C:\Windows\System32\igfxtray.exe"; // For debugging purposes System.Diagnostics.Process.Start(s.Process); icon.ShowBalloonTip(2000, "StartupManager", "\"" + s.Name + "\" has been started.", System.Windows.Forms.ToolTipIcon.Info); } catch (System.ComponentModel.Win32Exception) { icon.ShowBalloonTip(2000, "StartupManager", "\"" + s.Name + "\" could not be found.", System.Windows.Forms.ToolTipIcon.Error); } }
