Can't install UWP-Driver
Hello,
After updating the windows OS (windows10 1909 to 20H2), the driver of RealSense D435 was overwritten by the Microsoft driver.
We want to install the UWP driver, but we failed to install.
An error message is displayed. please show the attachment.
Have anyone experienced this kind of symptom? If any, how did you resolve it?
Regards,

Hi Eriko Mogi The RealSense UWP driver only needs to be installed if you widh to interface with hardware or software that supports Microsoft's Universal Windows Platform (UWP), such as the Microsoft HoloLens headset. Otherwise, the UWP driver does not need to be installed to use RealSense on Windows.

Another RealSense user recently experienced problems (though not with UWP) when their Windows build was updated from 1909 to 2004

Build 2004 and the 20H2 build that you are using have the same set of operating files, according to Microsoft.
The only solution that I can suggest is returning to Windows build 1909 if possible to see whether this causes the installation problem to disappear.

Hi Marty, Thanks for your replay. let me ask questions, please.
1.
You taught me the following.
The RealSense UWP driver only needs to be installed if you widh to interface with hardware or software that supports Microsoft's Universal Windows Platform (UWP), such as the Microsoft HoloLens headset. Otherwise, the UWP driver does not need to be installed to use RealSense on Windows.
If we do not install the UWP driver, can we see the RGB and depth stream with Realsense Viewer?
D435 is not recognized as a device.
2.
Can I get the older versions of UWP driver?
I found the latest one, but I could not find older versions.

1. Yes, you do not need the UWP driver to use the RealSense Viewer. Detection of the camera is not dependent on the UWP driver, so there may be some other issue that is preventing detection.
If you are using Windows, please use the instructions in the link below to check whether camera access is set to On in the Windows privacy settings.

2. Older versions of the UWP driver are not available any more, only the latest (currently 6.1.160.22)

Thanks for your reply.
I check the setting of camera access, but it set to On.
Do you have any other hints? Is there anything else I should check?
I'm sorry for asking questions.
Is it okay to update windows OS with connecting D435? Should I disconnect D435?
After updating OS, D435 is not recognized.

Having the camera plugged in during a Windows update should not affect the camera hardware (though Windows updates may introduce software issues that affect the camera's ability to operate in that Windows version).
It is also fine to unplug the D435 and then re-insert it into the USB port.
-
Is the camera detectable in the Windows Device Manager under its 'Cameras' category?
If it is detectable in the Device Manager, have you tried the camera with RealSense programs other than the RealSense Viewer? The link below describes how to activate the rs-capture example program in Windows.

Certainly, antivirus software is installed on our computers. But one succeeds and the other fails.
"success" means that I can see the stream on RealSense Viewer.
I got the information about device manager following.
Why these differences occur about Caption?
For KT01_AFTER, the RealSense was not detected on Viewer.
-
When you say "but one succeeds and the other fails", do you mean that you have tried the camera on two different computers that have antivirus software installed and the camera works on one of these computers but not the other?
If a D435 is identified as a D430 then this indicates that the firmware driver is not identifying the RGB sensor of the camera on that particular detection of the camera.
Since the camera can correctly be identified sometimes as a D435, this suggests that the camera's internal cable that connects to the RGB sensor component is okay and is not detached.
If the camera does work on one computer but not another, this makes me think that the firmware driver may not be the source of the problem. This is because the firmware is stored inside the camera hardware and not on the computer, so firmware related problems on one computer may also occur on another computer because the problem is carried between computers inside the camera.
Going back to the beginning of this case, the problem started when the Windows build updated from 1909 to 20H2. If the camera is having problems on one computer but works on another, is the other computer still using an earlier Windows build than 20H2?

Hello MartyG,
I work with Mogi-san for the issue. The one she mentioned is a set of PC and D435, KT02 in the table. The other is another set of PC and D435, such as KT01 or KT03.
BEFORE in the table mean Windows 10 1909 and AFTER; 20H2. All PCs are updated to 20H2. Then, some works fine and others don't.
Regards,
Ohara

Thanks very much Eriko Mogi and Shigeyoshi Ohara for your patience and for providing the further information. It sounds as though KT01 is the computer that the camera does not work with, but it works fine with KT02 and KT03. Is that correct please?
I went through the case from the beginning and it does not sound as though the RealSense SDK has been updated since the beginning of the case. Would it be possible to run the Windows installer file for the RealSense SDK called Intel.RealSense.SDK-WIN10 on your KT01 computer? This is the automated installer from the Assets file list on the SDK 'Releases' page.
If you previously installed the RealSense SDK on Windows using this method then the installation process will overwrite the SDK that was previously installed. If the problems that you are experiencing are related to damaged SDK files then this overwrite might correct the problem.

Hi Shigeyoshi Ohara Most of the packages are not large in size and so there is no harm in just clicking Next to install all suggested options.
If you do need to reduce the install size then when the RealSense SDK first launched at the end of 2017, the only suggested options in the installer were the Intel RealSense Viewer, C / C++ Developer Package and the Python Developer Package.
