Fix Rstrui.exe error in Windows 10

High Dynamic Range or HDR is a technique that’s used to create lifelike videos which have improved and better dynamic range, especially when it comes to details. And as you know, Windows 10 supports the steaming of HDR videos as long as the display supports it and it comes with the option to enable the HDR Playback for Windows 10 Video Streaming apps. However, before you can get the best viewing experience, you need to calibrate the display further for HDR video on your Windows 10 PC. Take note that even when you have the HDR Playback feature enabled on your computer, you still need a display that supports it. To make sure that your display supports this feature, you can use the DirectX Diagnostic Tool to have the display correctly wired and have the latest WDDM 2.4 drivers installed as well as set the other settings properly. Once you’ve made sure that your computer’s display really supports HDR and you’ve already enabled the HDR Playback feature, now it’s time for you to calibrate. Remember that when you calibrate the display, you should make an external monitor your primary display if you are using it for HDR and then adjust the settings to your liking. And if you are calibrating for primary display, you need to disconnect all other displays.

Follow the given steps below to calibrate the display of your PC.

• Step 1: You need to open the Video Playback first. To do so, navigate to Settings > Apps > Video Playback.
• Step 2: Under the Video Playback settings, uncheck the “Don’t increase display brightness when watching HDR video on battery” checkbox or plug in your PC.
• Step 3: Next, click the “Change calibration settings for HDR video on my built-in display” link located on the right side.
• Step 4: After that, click on the Play button located on the left side to play the video. Then move the sliders to the left or right so you can start to calibrate. Once you see that the quality of the image is to your preference, stop.

Note: Just a tip when calibrating – you just have to find the right balance between the details in the darker parts of a scene. For instance, you have Mountains in the background and buildings in the front – you need to drag the slider to the right to add more details to the snow on the mountain or drag the slider to the left to add more details to the buildings. After that, you can pause the video and exit the full-screen mode. Keep in mind that the quality of HDR depends on you as it is a personal choice. Some users might like a brighter shade while other ones want the darker shade so it really depends on your taste. If you are not satisfied with how your HDR turned out, you can just try calibrating the display again. Simply go back to the default HDR video calibration and click or tap the Reset calibration button. Another thing to remember. First, you can only see HDR content on the full screen and if you’re using a laptop, you need to make sure to watch videos when plugged in and check that the battery settings won't’ lower the brightness.

What is Error Code 29?

Code 29 is a Device Manager error commonly seen whenever a hardware device driver reports a problem. This error code indicates that the resources needed for operation are not available.

The computer hardware basically requires drivers to interface with the operating system. Drivers comprise multiple components and are supplemented with other resources provided by the BIOS (a physical chip on the motherboard).

The BIOS contains a set of basic input and output instructions for the computer system to boot, load drivers, and more.

Its firmware provides resources that drivers require to interface with other essential components. However, when the firmware fails to provide the requested resources, the device drivers stop functioning; this results in error codes like code 29.

Error code 29 is usually displayed in the following format:

If you encounter an error message saying, “The ordinal xxx could not be located in the dynamic link library C:/Program Files (x86)/Microsoft VS Code Insiderscode – insiders.exe“ and you see a reference of a missing DLL file, then this indicates that the software is trying to locate the related DLL file, however, it is missing, hence the error. The error mentioned “Ordinal” which refers to the order of a number mathematically, e.g. 1st, 2nd, etc. And in this error message, the ordinal is referring to an Xth file of an XX.DLL file which is missing which is why you’re getting this kind of error. When you get this particular error, it means that your computer is missing the Microsoft Visual C++ Redistributable program. As per the error message, XXX is a number that in turn is the Ordinal. There is also another common error related to Ordinal which says, “The ordinal 12404 could not be located in the dynamic link library mfc90u.dl”. The error message could be referring to any DLL in the message. And since all these DLL files are part of the package, the error changes quite a bit as the Visual Studio looks for that DLL file. To fix this error, here are some suggestions that might be of help.

Option 1 – Try installing Microsoft Visual C++ Redistributable

As pointed out earlier, the error pops up when the Microsoft Visual C++ Redistributable program is missing on your computer. Thus, you need to download it from the official website of Microsoft. Once you’ve downloaded the Microsoft Visual C++ Feature Pack Redistributable Package, install it and then check if the error is now fixed.

Option 2 – Try to install OpenSSL

If you encounter the same error message but it points out that the LIBEAY32.DLL file is missing, then you have to install OpenSSL. In such a case, you will see the following error message:

“Ordinal not found. The Ordinal [Xxxx] could not be located in the Dynamic Link Library Libeay32.dll.”

 Make sure that when you install OpenSSL, you do it into the Windows system directory since the Libeay32.dll file is related to security.

Option 3 – Try to check Windows Updates

There are instances when Microsoft rolls out the framework and related updates via Windows Updates. It could be that an update related to DLL is still pending which is why you need to check Windows Updates. To do so, go to Settings > Update and Security and from there check if there is any pending update. If there is, you need to install that update and then restart your computer if needed.

If you are browsing the internet using the Google Chrome browser in your Windows 10 computer but you suddenly encounter an error message that states, “ERR_ICAN_NAME_COLLISION”, read on as this post will walk you through in fixing the problem. Here’s the full content of the error message:

“The site can’t be reached, This site on the company, organization, or school intranet has the same URL as an external website. Try contacting your system administrator. ERR ICAN NAME COLLISION.”

This kind of error is caused by an error in a private namespace or a random redirection to an incorrect proxy server. There are several ways to fix this error. You can try to check the integrity of the Hosts file or check the proxy.
