Awesome thanks guys
It is working like a charm with the testing I have done so far!

Yes, just use the same component guid/key path thing and install to the same
location and then it just works.
SharedDllRefCounts are for integrating with non-MSI installs. If your Dll is
installed by your MSI and you know that a non-MSI install might also install
it afterwards then set the shared ref count so that the non-MSI setup (using
that shared count) won't delete your file/registry entries if it is
uninstalled. That's the only situation I know of in which you need to set
SharedDllRefCount - if MSI sees one already there for the Dll it will
increment it anyway.

Not 100% certain on this but I always assumed shared components should use
the same component ID, and should all install to the same location. I would
also avoid SelfReg like the plague.

"The same component GUID can be registered by multiple products. This
provides for multiple products to install shared resources. However, it is a
common misconception that only by defining the same GUID is a shared
component defined. Both the GUID and the component key path must be the
same."

Hi folks,
sigh I can't remember this for the life of me...
Okay I have 2 products called A and B
Within A I have File_X in two different MSI's being installed to 2 different
placesIn B I have File_X being installed to another location File_X is a COM
file that is registered So if I want to install A then B or B then A and
later uninstall one of them I do NOT want the COM registration to be
removed...
INSTALL A:
MSI 1:
<Component Id="cmp_TL_MyFile" Guid="{D4EDBCFA-...}" Shared="yes"
SharedDllRefCount="yes"> <!-- Need to use SelfRegCost and the
Class/TypeLib elements in order for the DLL to load properly -->
<File Id="file_TL_MyFile" KeyPath="yes"
Source="$(var.somePath)\TL_MyFile.dll" SelfRegCost="1">
<Class Id="{F1A000BF-CF05-...}" Context="InprocServer32"
Description="TL_MyFile OleDocumentProperties" ThreadingModel="apartment">
<ProgId Id="TL_MyFile.OleDocumentProperties" Description="My Company OLE
Document Properties Reader 2.1" /> </Class>
<TypeLib Id="{F1A000BF-CF00-...}" Description="My Company OLE Document
Properties Reader 2.1" HelpDirectory="WixLibRedirectFolder" Language="0"
MajorVersion="2" MinorVersion="1"> <Interface
Id="{F1A000BF-CF01-...}" Name="_OleDocumentProperties"
ProxyStubClassId32="{00020424-...}" /> <Interface
Id="{F1A000BF-CF02-...}" Name="Summar
yProperties" ProxyStubClassId32="{00020424-...}" />
<Interface Id="{F1A000BF-CF03-...}" Name="CustomProperty"
ProxyStubClassId32="{00020424-...}" /> <Interface
Id="{F1A000BF-CF04-...}" Name="CustomProperties"
ProxyStubClassId32="{00020424-...}" /> </TypeLib>
</File> </Component>
MSI 2:
<Component Id="cmp_TL_MyFileDll" Guid="{3969ED7B-...}" Shared="yes"
SharedDllRefCount="yes"> <!-- Need to use SelfRegCost and the
Class/TypeLib elements in order for the DLL to load properly -->
<File Id="file_TL_MyFileDll" KeyPath="yes"
Source="$(var.somePath)\TL_MyFile.dll" SelfRegCost="1"> <Class

Reader 2.1" HelpDirectory="WixLibRedirectFolder" Language="0"
MajorVersion="2" MinorVersion="1"> <Interface

s" ProxyStubClassId32="{00020424-...}" /> <Interface

ProxyStubClassId32="{00020424-...}" /> <Interface
Id="{F1A000BF-CF04-...}" Name="CustomProperties"
ProxyStubClassId32="{00020424-...}" /> </TypeLib>
</File> </Component>
INSTALL B:
<Component Id="cmp_TL_MyFileDll" Guid="{FF5D759D-...}" Shared="yes"
SharedDllRefCount="yes"> <!-- Need to use SelfRegCost and the
Class/TypeLib elements in order for the DLL to load properly -->
<File Id="file_TL_MyFileDll" KeyPath="yes"
Source="$(var.somePath)\TL_MyFile.dll" SelfRegCost="1"> <Class
Id="{F1A000BF-CF05-...}" Context="InprocServer32" Description="TL_MyFile
OleDocumentProperties" ThreadingModel="apartment"> <ProgId
Id="TL_MyFile.OleDocumentProperties" Description="My Company OLE Document
Properties Reader 2.1" /> </Class> <TypeLib
Id="{F1A000BF-CF00-...}" Description="My Company OLE Document Properties
Reader 2.1" HelpDirectory="DIRECTORY_PATH_PLUGINS" Language="0"
MajorVersion="2" MinorVersion="1"> <Interface
Id="{F1A000BF-CF01-...}" Name="_OleDocumentProperties"
ProxyStubClassId32="{00020424-...}" /> <Interface
Id="{F1A000BF-CF02-...}" Name="SummaryPropertie
s" ProxyStubClassId32="{00020424-...}" /> <Interface
Id="{F1A000BF-CF03-...}" Name="CustomProperty"
ProxyStubClassId32="{00020424-...}" /> <Interface
Id="{F1A000BF-CF04-...}" Name="CustomProperties"
ProxyStubClassId32="{00020424-...}" /> </TypeLib>
</File> </Component>
The component GUID is different for each component The Class ID is the same
for the three components The TypeLib ID is the same for the three components
The Interface ID's are the same for the three components
If I uninstall A, and B is left behind, File_X is not longer registered as a
COM object...
What am I doing wrong?
Thanks,
Steveps have a great weekend all!
