Just to confirm, the registry settings are reverting to their defaults even if I just log off and back on again, I don't have to actually reboot.

OK, now back working as before, with rather less clutter in the Elantech folder! Settings still not being saved over a reboot. Only ETDCtrl.exe is now running, as ETDIntelligent.exe isn't present any more of course. ETDCtrlHelper.exe still throwing the same error when run manually.

I tried substituting ETDCtrl.exe and ETDCtrlHelper.exe. Now I'm getting "ETDCtrl.exe has encountered a problem and needs to close".

11.5.4.2 did produce the same result. I've now restored it to the semi-working version, with the files and ETD.sys from 11.4.14.1. This is what I now have - ETDAniConf.exe 11.0.0.7 ETDCtrl.exe 11.0.0.1 (running) ETDCtrlHelper.exe 10.0.0.83 (not running) ETDDeviceInformation.exe 11.1.0.1 ETDIntelligent.exe 11.0.0.6 (running) ETDService.exe 10.0.0.4 (not running) ETDUn_inst.exe 10.0.0.9 ETD_DLL.dll 10.0.0.4 ETDApi.dll 10.0.0.9 ETDApi32.dll 10.0.0.5 ETDApix.dll 10.0.0.111 ETDCmds.dll 10.0.0.96 ETDFavorite.dll 10.0.0.82 ETDMcpl.dll 10.0.0.80 ETDUninst.dll 10.0.0.1 ETD.sys 11.0.0.31 Good to see it so near to working with all version 10 dlls! There are other exe files in the folder, but they are mostly control panels.

I tried copying all the files from 11.5.6.6 across to the Elantech folder, and the driver worked as before. I then tried also copying ETD.sys (version 11.0.0.6) across to system32\drivers and the driver no longer worked. Still no error in Device Manger, but the system tray icon was now "dead". The same two programs are running in the background. I'll download and try with 11.5.4.2 next.

LOL, thanks Jaclaz! As I said to dencorso late last night, the outstanding problem with the driver as it is now is that the settings are not actually being saved. They can be changed, and the touchpad behaviour changes, which is an enormous advance on anything we've had on XP before, but when the system is rebooted the settings go back to the defaults. ETDCtrl.exe is running fine, but instead of ETDCtrlHelper.exe, what is running with it is ETDIntelligent.exe, a program I've never seen running before! If I try to run ETDCtrlHelper.exe, it throws the "UnregisterPowerSettingNotification" could not be found error. ETDIntelligent.exe does not exist in 11.5.20.3, so I can't quite see how it's running, because it can't be mentioned in the INF!

Good idea Den, but we're not quite out of the woods yet! I've now discovered that although I can change the touchpad settings on XP, and they work, they are not being saved properly, because when I reboot they've reverted back to the defaults. We are so close now though that I'm sure this can be resolved. I will pick this up with Jaclaz tomorrow. Cheers, Dave.

I've just realised that 11.5.20.3 is showing as not signed on XP even with its original INF. Is that what you would expect? Anyway, I installed it using its normal INF file, and then copied all the files from 11.4.14.1 to the Elantech folder, and replaced the ETD.sys file with the 11.4.14.1 version as well. And............ IT WORKS! I now have a working driver in Windows XP!! I cannot thank you enough Jaclaz! Having worked with you so often here in the past, I cannot believe that this was just a speculative shot in the dark. You must have known that this might work, and it has! I am so happy!

The Device Manager is fine, it's saying the device is working properly. It's the old problem that the device isn't being identified correctly by the tab in the Mouse Properties. I'm pretty sure that as long as it's appearing just as a generic "Standard PS/2 Mouse", it will not work. The installation log looks OK. 10.0.5.4Install.txt

Your modified INF (327KB) is actually bigger than the original (325KB) is that right? Anyway, installing through Device Manager with your INF sadly does not produce a working driver. There is an icon in the system tray, an Elan style one, not an Asus style one, but it doesn't animate when the touchpad is used. There is an Elan tab on the Mouse Properties again, but again it stows the device as a "Standard PS/2 Mouse" not a smart pad, and the options button is greyed out. Right clicking on the icon has an "Asus Smart Detector" option which I've not seen before, and that brings up a control panel, but it has no options in it. "ETD Control Center" and "ETD Control Center Helper" are both running, which is a good sign! Device Manager says the mouse is now an "Elan PS/2 Port Smart-Pad".

Tried that, I then had to OK the install, as expected, but the driver still installed and is working fine!

OK, here's the logs. I hope they provide some clues. The log of the default install is a lot bigger than the log of the modified install! NormalInstall.txt NormalUninstall.txt ModifiedInstall.txt ModifiedUninstall.txt

OK I did my registry restore test, and restoring the registry does make the driver work again. So I think that proves that the problem with the modified INF is in its registry sections, not anything to do with what files are copied or not copied. One other thing I've now noticed is that when the driver is uninstalled after an install with the default INF, the mouse correctly reverts to its previous name in Device Manager (Microsoft PS/2 Mouse). After an uninstall of an installation with the modified INF, it remains as "Elan Input Device" and the driver has to be manually rolled back to revert it correctly. Another symptom of a problem with the registry entries in the modified INF I assume, in the uninstall section.

Certainly the driver signing is broken when the install is done with the modified INF, I have to OK the install, which I don't have to with the default INF. I assume that's expected behaviour, as the driver cannot be considered to be still signed if the INF has been "tampered with"!

Yes, that certainly seems to be the case! How about I reinstall the driver from the default INF, using Device Manager, and then when I have a working driver I back up the whole registry with ERUNT, then uninstall the driver and do the same install with your INF, which will presumably result in a non-working driver, and then restore the whole registry back again from the backup I made while the driver was working? If the driver then works, presumably that will prove that the problem is in the registry, not missing files or anything like that. If the driver still doesn't work, that means it's a file problem, not a registry problem. That will at least narrow things down a bit perhaps.

OK, I uninstalled, and reinstalled using the default INF. I went and checked, and the ETDService service wasn't installed! I hadn't noticed until then that it wasn't actually there any more with a normal INF-only install. So, it must be another thing (along with the avi files) that is installed by the setup program, not by the INF! More significantly, it also means that it's not necessary, as the driver was still working fine! Anyway, attached is the differences between the two registry snapshots, only including the entries which appeared to be Elan related. The whole thing was huge of course! HTH. ElanDifferences.reg

OK, I'll uninstall again and then install using the original INF, and make a registry snapshot. I'll then uninstall again, and reinstall using your cut down INF. I'll then do another registry snapshot and use Nir Sofer's program to compare them, and see if we can see what the relevant differences are.

OK, I think I see how it works now! Running <ETDService.exe -install> installs the service, <ETDService.exe -uninstall> removes it. If I install it and reboot, the service is then running fine. So, somehow when the normal INF is used, that <ETDService.exe -install> command is presumably being run, but I can't see where it is! The driver still isn't working, ETDCtrlHelper.exe isn't running, and starting it manually does not make any difference.

11.5.20.3 installs from Device Manager using the default INF absolutely fine, fully working. I then tried installing exactly the same way using your latest INF, and again the service was not installed. The data for it is not in the registry. It's the service called "ETDService" which is missing, the service called "ETD" is installed fine. As you say "ETDService" isn't mentioned in the default INF, only as a file name, which is odd!

Just tested in Internet Explorer 11 on Windows 10 and the behaviour is exactly the same! I guess this has been changed, and the warning now only appears once even if you don't check the "do not show again" option.

I've now tried installing 11.5.20.3 using Device Manager. Two versions of "Elan Input Device" were offered (not "Elan PS/2 Port Input Device", which must be something different!) This time it didn't transfer the AVI files, so it looks as if you were right about the setup.exe doing it intrinsically, which is rather odd I would have thought when they are normally in the INF! Unfortunately, it's also not working. Again the Elan Service hasn't been installed. Only ETDCtrl.exe is running. Running ETDCtrlHelper.exe still works, but doesn't change anything.

I installed by running "setup.exe". I've just tried with version 11.5.6.6, using your INF and it didn't work. Again the completed window showed two devices, but this time one had failed! Previously with 11.5.20.3 there were also two devices, but both had apparently succeeded. The mouse was "Elan PS/2 Port Smart-Pad", not showing any errors. The touchpad worked but the settings are at default and can't be changed. There was a "dead" icon in the system tray. ETDCtrl.exe and ETDCtrlHelper.exe are both running, but not the Elan Service. It doesn't seem to have been installed as it's not in the Services list as it normally is. I then tried updating the mouse driver in Device Manager, as "Elan PS/2 Port Input Device" is also offered, which is what it is with 11.5.20.3. (I'm wondering if "Elan PS/2 Port Smart-Pad" and "Elan PS/2 Port Input Device" are the two devices being displayed on the installation completed window? ) Doing that produced the same result as before, although I now seem to have "ETD Gesture" running, which I didn't think was before! Still no Elan Service though.

It's working fine with the modified INF. It did take an extraordinarily long time to install though, I was on the point of giving up on it when it suddenly completed! The install completed window showed two identical instances of the device, which I've not seen before, there's always been only one before. It seems to be installed and working normally though. It has still transferred the AVI files. I will now do the second part of the test.

Even when the two files are running (and the Elan Service which always runs) the system tray icon does not come back, and the driver is still not working. Running the Asus control panel manually and changing the settings does nothing, and does not change the settings in the registry. Changing the registry setting manually also has no effect.

Taking ETDapi.dll down to version 10.0.0.6 was fine. Unfortunately, taking ETDapix.dll down to version 10.0.0.98 stopped the driver from working properly. ETDCtrl.exe and ETDCtrlHelper.exe are no longer running, and there is no longer an icon in the system tray. The touchpad settings have held though, "tap to click" is still disabled. Changing the setting in the Asus control panel now has no effect, and nor does changing the setting in the registry.
