Can't run DisplaySwitch.exe

[blaher]

I can manually run C:\Windows\System32\DisplaySwitch.exe, but it's stopped working from within EG, perhaps because of the Creators Win 10 update?

I've tried running as an admin too, but it used to work without doing that.

Any ideas?

I am not sure what DisplaySwitch.exe is.. but from what the name implies is it does something with your monitors or display adapters..

With each new release of Windows 10 Microsoft keeps on locking out various components of the Windows driver system. they are doing this because they are trying to lock out the OS from malicious code from malware and spyware.. The unfortunate thing is it's turning the OS into something like a Crapintosh. where you can't do anything in it very easily. They seem to be hammering down on what applications/drivers are able to manipulate the OS to do. So things like an application is not allowed to write anything to the Program Files directory. or the removal of unsigned drivers. I am sure there are more we just haven't discovered them as of yet. And the really messed up thing is that Microsoft is not telling anyone of these changes. Or if they are they are giving incorrect information about it. It's creating a large problem for us over here in EG land.

check the file permissions. I just looked it up and it's a part of windows. and windows may have chnage the permissions to the file.. if it works as administrator this is probably what the issue is.

You can't change the permissions, or reename/delete it. Only 'TrustedInstaller' has full permission. The rest just have read & read and execute.

if it works as administrator this is probably what the issue is.

It doesn't in EG, with or without admin ticked.

I use it for my HTPC to swap between my monitor and my TV.

If I run a batch file with:

Code: Select all

start "" "C:\Windows\System32\DisplaySwitch.exe" /clone
exit

It does the same as pressing "Win key + P" (for Project), and then selecting "Duplicate".

Code: Select all

start "" "C:\Windows\System32\DisplaySwitch.exe" /external
exit

Does the same as pressing "Win key + P" (for Project), and then selecting "Second screen only".

I've tried running a batch file from EG, a shortcut to the .bat file, and tried to use Send Keystrokes, but unfortunately the emulation of {Home] doesn't work so I can't do:
{Win+P}
{Home}
{Down}
{Return}
{Esc}

for Duplicate

or

{Win+P}
{End}
{Return}
{Esc}

for Second screen only.

All methods fail. I've tried EG's "Set Display Preset" but it doesn't differentiate between the PC monitor and the TV, just the resolutions...and then only sometimes.

Not sure what to try next, maybe nVidia control panel has a hotkey or something.

how come you are using batch files?

you can use the Run Application action without the need for the batch files.

and I can locate the keycode for the home key as well.. give me a minute on that one.. I did up a post a while back that had all of the keycodes listed..let me go and find it.

ok so here is the complete list of keys that can be used in the Send Keys action for the home key it could be that it is being sent as the number pad home. so you will probably want to try out the ones that have OEM in them or the ones that start with a U

Code: Select all

how come you are using batch files?

you can use the Run Application action without the need for the batch files.

I can manually run C:\Windows\System32\DisplaySwitch.exe, but it's stopped working from within EG

and I can locate the keycode for the home key as well.. give me a minute on that one.. I did up a post a while back that had all of the keycodes listed..let me go and find it.

I circumnavigated the problem by making a windows shortcut to the .bat file, then a windows keyboard shortcut, then emulated that keyboard shortcut in EG with Send Keystrokes...hardly ideal, but I need something at the moment. Frustrating having my Kodi setup down. The not found error also hoses the rest of EG and its macros because no events are received until after you press OK on the error box.

paste this into your tree and give it a go. maybe it will work for ya

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="0.5.0-rc4">
    <Action XML_Guid="{52AEA35B-5E5F-4085-9AB1-D87D5371B9BE}">
        System.Execute(u'DisplaySwitch.exe', u'/external', 3, False, 5, u'c:\\Windows\\System32', False, False, u'', False, False, False, False)
    </Action>
</EventGhost>

The same error unfortunately.

it strange because it's stating that it can't find it. try this one. this should be a different location for the program.

This one works for me (Win10-64Bit):

Code: Select all

<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="WIP">
    <Action XML_Guid="{873B48B5-EDD2-459D-8652-DA9A0077D225}">
        System.Execute(u'DisplaySwitch.exe', u'/external', 0, False, 2, u'', False, True, u'', False, False, False, False)
    </Action>
</EventGhost>

No file path, just the file name. WOW64 filesystem redirection disabled.

Edit: The same error as posted above.

That did the trick, thank you!

where there is a will there is a way..... thanks topix for the help... I am in the stone age with windows 7 but it's solid like a rock... HA pun intended!!


my workstation up time... 105.12143766203703703703703703704 days.... and the only reason why i powered it off then was because I had to move my desk when i cut the floor open to do some work on my house. before that it had to be close to a year.

how about your Windows 10 up time.. it has to be an actual work station.. meaning you actually use it and it's not sitting in a closet somewhere just humming away.
