Using HLP files in Windows 10

It is amazing how some vendors of libraries in the automation industry still require you to read help files in the old Microsoft hlp format.  Trying to open such a file results EDGE to show you the following screen.
Image Error opening Help in WIndows-based programs: "Feature not included" or "Help not supported"

If you think you can download and install the version for Windows 8.1. you are wrong. But do not throw away your downloaded MSU-File (for Windows 8.1 x64 the name is Windows8.1-KB917607-x64.msu).

Start your command prompt as Administrator!

imageFirst extract the content of the MSU File to another directory:

md ContentMSU
expand Windows8.1-KB917607-x64.msu /F:* .\ContentMSU

Now we can extract the contained CAB-File:

cd ContentMSU

md ContentCAB

expand Windows8.1-KB917607-x64.cab /F:* .\ContentCAB

This will extract 279 files.  Depending on your culture and language settings we need to locate the right MUI-File. My language is german so I use “de-”. English folk use “en-“.

cd ContentCAB
dir amd64*de-*.
People who use the x86 variant need to run “dir x86*de-*.”
Navigate to the given path, in my case

cd amd64_microsoft-windows-winhstb.resources_31bf3856ad364e35_6.3.9600.20470_de-de_1ab8cd412c1028d0

Here we will find “winhlp32.exe.mui”. We need to replace %SystemRoot%\de-de\winhlp32.exe.mui with our new file:

takeown /f "%SystemRoot%\de-de\winhlp32.exe.mui"
icacls "%SystemRoot%\de-de\winhlp32.exe.mui" /grant "%UserName%":F
ren %SystemRoot%\de-de\winhlp32.exe.mui winhlp32.exe.mui.w10
copy winhlp32.exe.mui %SystemRoot%\de-de\winhlp32.exe.mui


 

takeown /f "%SystemRoot%\winhlp32.exe"
icacls "%SystemRoot%\winhlp32.exe" /grant "%UserName%":F
ren %SystemRoot%\winhlp32.exe winhlp32.exe.w10

cd ..

dir *.exe /s
Find the right path starting either with amd64 or x86 and navigate to it
cd "amd64_microsoft-windows-winhstb_31bf3856ad364e35_6.3.9600.20470_none_1a54d9f2f676f6c2"
copy winhlp32.exe %SystemRoot%\winhlp32.exe

  1. Thank you for easing the pain post-upgrade.

    For EN-US, on a x86 machine, I did:

    takeown /f „%SystemRoot%\en-us\winhlp32.exe.mui“
    icacls „%SystemRoot%\en-us\winhlp32.exe.mui“ /grant „%UserName%“:F
    ren %SystemRoot%\en-us\winhlp32.exe.mui winhlp32.exe.mui.w10
    copy winhlp32.exe.mui %SystemRoot%\en-us\winhlp32.exe.mui

    takeown /f „%SystemRoot%\winhlp32.exe“
    icacls „%SystemRoot%\winhlp32.exe“ /grant „%UserName%“:F
    ren %SystemRoot%\winhlp32.exe winhlp32.exe.w10

    cd ..

    cd „x86_microsoft-windows-winhstb_31bf3856ad364e35_6.3.9600.20470_none_be363e6f3e19858c“
    copy winhlp32.exe %SystemRoot%\winhlp32.exe

  2. Merci beaucoup pour ce tutoriel : une pure merveille!
    Pour la version française, toujours sous W10 64 bits, il suffit de remplacer, dans les instructions en ligne de commande, „de-de“ par „fr-fr“.
    danke sehr

  6. „It is amazing how some vendors of libraries…..“ – well, some USERS, (remember them?) have older programs because they can’t afford to upgrade to the latest version OR there is no current program that does the same as the old one.YOU may have unlimited funds or the ability to write new programs, users generally don’t have either.
