WiX Heat.exe generates different output after VS2008 -> VS2015 upgrade

We execute the following command line with heat (3.0.5210.0):

heat.exe -srd -suid file OurLib.dll -out bin_OurLib.tmp

OurLib.dll is a VC++ 2008 dll file, it's a COM component.

Output (bin_OurLib.tmp)

    <?xml version="1.0" encoding="utf-8"?>
    <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
        <Fragment>
            <DirectoryRef Id="TARGETDIR">
                <Component Id="OurLib.dll" Guid="PUT-GUID-HERE">
                    <File Id="OurLib.dll" KeyPath="yes" Source="SourceDir\OurLib.dll">
                        <Class Id="{B1AB297C-1BC6-65E1-A7C1-A1833DFAED6A}" Context="InprocServer32" Description="OurProduct.OurLib">
                            <ProgId Id="OurProduct.OurLib" Description="OurProduct.OurLib" />
                        </Class>
                    </File>
                </Component>
            </DirectoryRef>
        </Fragment>
    </Wix>

This works fine. Now we updated the VS to 2015, and compiled OurLib with it. Running the same heat command now results in different output:

    <?xml version="1.0" encoding="utf-8"?>
    <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
        <Fragment>
            <DirectoryRef Id="TARGETDIR">
                <Component Id="OurLib.dll" Guid="PUT-GUID-HERE">
                    <Class Id="{B1AB297C-1BC6-65E1-A7C1-A1833DFAED6A}" Context="InprocServer32" Description="OurProduct.OurLib">
                        <ProgId Id="OurProduct.OurLib" Description="OurProduct.OurLib" />
                    </Class>
                    <File Id="OurLib.dll" KeyPath="yes" Source="SourceDir\OurLib.dll" />
                    <RegistryValue Root="HKCR" Key="CLSID\{B1AB297C-1BC6-65E1-A7C1-A1833DFAED6A}\InProcServer32" Value="&quot;[#OurLib.dll]&quot;" Type="string" Action="write" />
                </Component>
            </DirectoryRef>
        </Fragment>
    </Wix>

And when wix is linking, it gives error:

error LGHT0130 : The primary key 'reg51A1FC16367511AF81E9B18CA009A1C6' is duplicated in table 'Registry'. Please remove one of the entries or rename a part of the primary key to avoid the collision.

Checking the wixobj file, reg51A1FC16367511AF81E9B18CA009A1C6 is related to line <Class Id="{B1AB297C-1BC6-65E1-A7C1-A1833DFAED6A}...." and <RegistryValue Root="HKCR" Key="CLSID\{B1AB.... - obviously.

Anwyay, this is obviously due to the generated wix output files are different. Why is that if compiling a dll with a newer C++ compiler will cause WIX HEAT to generate different output, while running the same options, etc.

And how can I have back the same "old" output, which we need.

Tried with -scom and -sreg, none of them gave back the "old" output.

Well primary key duplicated means you've got that same RegistryValue in two different places in your wix source code somehow.

Or maybe the newer DLL is self-registering differently? It's putting the InProcServer32 value in quotes. I don't think that's normal.

Or have you checked that your 2008 and 2015 DLL source and project files are identical? The VS project upgrade process changes things...
