Microsoft HTML Help Executable



In the HIDPI environment, the size of the font, as well as the size of the picture is confusing.


the origin manifest:



<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

wrong:



<asmv3:application>

<asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">

<dpiAware>true</dpiAware>

</asmv3:windowsSettings>

</asmv3:application>



should be:


<asmv3:application>

<asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2017/WindowsSettings">

<gdiScaling>true</gdiScaling>

<dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">true/pm</dpiAware>

Thanks dalchina and Bree for your quick responses once more.

I have now been informed by my brother that dalchina's instructions to merge the chm registry key has worked and the Microsoft HTML Help Executable icon now appears in Settings > Apps > Default Apps > Choose application by file types and all is working fine.

Once more thanks for your help. *Wink
