Device manager error

[DrDillis]

I wonder if anyone else has had issues trying to install this device manually with device manager. I've tried this while running device manager as an administrator and ran the bat file first. Even after rebooting I still get

"An error has occurred during the installation of the device."

I hope something can be done, it'd be lovely to enable a few extra monitors for VR use.

Did you try copying and pasting the text of the bat file into an administrator command prompt with the working directory where the files were extracted? I think that has a better success rate.

Thanks, works now, I think the issue you were having with other people saying it wont install the cert from the .bat was because the bat looked like this;

./CertMgr.exe /add IddSampleDriver.cer /s /r localMachine root

but needed this:

CertMgr.exe /add IddSampleDriver.cer /s /r localMachine root

I was going to post this as a separate issue, but it relates to the above comment.
Batch file has a typo, second char should be "\" not "/" as it refers to a Windows path.

EDIT: github deleting backslash

I get this error when trying to install in device manage (it half way succeeds)r:

This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

This is fixed here

You can also get this error by not placing option.txt in C:\IddSampleDriver

I also had an issue with it not registering the certification, despite running the batch file as admin. When I opened an admin command window in the folder and ran it, it worked. The reason is that when running as admin, the working directory is c:\system32, so the ".\CertMgr.exe" part doesn't work, as it's not in the system32 directory. There's a very easy fix for this, to ensure others don't run into the issue. Simply change it to "%~dp0\CertMgr.exe" or, better yet, to avoid the other issue I had, which is that the install guide here didn't specify this needs to be in C:\iddSampleDriver to work, have the batch file ask the user if it's ok to copy the files there, then do so and then register it.

Here's a batch file that will do this, which will simplify this process and help prevent people having issues:

`@echo off
setlocal enableDelayedExpansion

REM Check if running with admin privileges
net session 1>nul 2>nul
if %errorlevel% neq 0 echo. & echo ERROR: RUN SCRIPT AS ADMINISTRATOR & echo. & pause & goto :eof

REM Check if in directory needed to work
if NOT "%~dp0"=="C:\iddSampleDriver" (
echo. & echo Files are currently in "%~dp0" and need to be in "C:\iddSampleDriver" to properly install and work. Would you like to copy them there and continue?& echo.
choice
if !errorlevel! equ 2 echo. & echo Installation canceled& echo. & pause & goto :eof
if !errorlevel! equ 1 (
if NOT exist "C:\iddSampleDriver" (
mkdir C:\iddSampleDriver 1>nul 2>nul
if !errorlevel! equ 1 echo. & echo ERROR: FAILED TO CREATE DIRECTORY "C:\iddSampleDriver" & echo. & pause & goto :eof
)
robocopy %~dp0 "C:\iddSampleDriver" /mir /is /it /im
if !errorlevel! gtr 7 echo. & echo ERROR COPYING WITH ROBOCOPY & echo. & pause & goto :eof
)
)

cls
C:\iddSampleDriver\certmgr.exe /add C:\iddSampleDriver\IddSampleDriver.cer /s /r localMachine root
if %errorlevel% equ 0 (
echo. & echo SUCCESS^^! & echo. & timeout /t 5
) else (
echo. & pause
)`

I'd also suggest adding in the install steps on the releases page to ensure it's in that directory, even though this updated batch script would do that, just in case.

%~dp0 should be appended to the path of the certificate so it finds it relative to the path of the script. The proper command in the bat file should be:

.\CertMgr.exe /add %~dp0IddSampleDriver.cer /s /r localMachine root

Also, See #26. CertMgr.exe is not even needed. Ultimately, installCert.bat should look like this:

@echo off

set CERTIFICATE="%~dp0IddSampleDriver.cer"

certutil -addstore -f root %CERTIFICATE%
certutil -addstore -f TrustedPublisher %CERTIFICATE%

pause
