[wix-users] Installation damaged by Windows update

I'm going to guess that MSFT doesn't want that component publicly registered. Trying to search information about it on Microsoft's web domain, I found this discussion "fixing" the documentation (of that time: ~6 years ago) to create a typelib (which compiled code can easily use to access unregistered COM).

Where did you find documentation specifying that it should be manually registered for you to use?

Subject: Re: [wix-users] Installation damaged by Windows update

I managed to discover what is missing after the Windows update. The
MSI installation package includes a Windows Script Component. The .WSC
file remains in place but the registration is removed from the
registry. The registry content is:

[HKEY_CLASSES_ROOT\CLSID\{2CC0D042-48FB-49E4-8282-33378FC9939B}]
@="FileDistributor"

[HKEY_CLASSES_ROOT\CLSID\{2CC0D042-48FB-49E4-8282-33378FC9939B}\InprocServer32]
@="C:\\WINDOWS\\system32\\scrobj.dll"
"ThreadingModel"="Apartment"

[HKEY_CLASSES_ROOT\CLSID\{2CC0D042-48FB-49E4-8282-33378FC9939B}\ProgID]
@="FileDistributor.WSC.1.07.05"

[HKEY_CLASSES_ROOT\CLSID\{2CC0D042-48FB-49E4-8282-33378FC9939B}\ScriptletURL]
@="file:///C:\\Program
Files\\ACME\\ProductManagement\\FileDistributor\\FileDistributor.wsc"

[HKEY_CLASSES_ROOT\CLSID\{2CC0D042-48FB-49E4-8282-33378FC9939B}\VersionIndependentProgID]
@="FileDistributor.WSC"

[HKEY_CLASSES_ROOT\FileDistributor.WSC]
@="FileDistributor"

[HKEY_CLASSES_ROOT\FileDistributor.WSC\CLSID]
@="{2CC0D042-48FB-49E4-8282-33378FC9939B}"

[HKEY_CLASSES_ROOT\FileDistributor.WSC.1.07.05]
@="FileDistributor"

[HKEY_CLASSES_ROOT\FileDistributor.WSC.1.07.05\CLSID]
@="{2CC0D042-48FB-49E4-8282-33378FC9939B}"

--- end of registry file ---

It is sufficient to merge the .REG file with the content shown above
the get a fixed installation. The corresponding WiX source file is
here:

<?xml version="1.0" encoding="utf-8"?>
<?define Files=$(env.BUILD_DIR)\ACME\ProductManagement\FileDistributor\Bin ?>

            </Component>
        </ComponentGroup>
    </Fragment>
</Wix>

The WSC files was first registered and the change in the registry
saved in a REG file. The WiX fragment was generated from the REG file.

The ComponentGroup is referenced in the single Feature in the Product
in the source file. All other component (groups) in the same (single!)
feature remain intact.

What might be wrong with that fragment?

Best regards,
Helge
