The following exception is being raised in my program.  How can I fix this?

System.IO.FileLoadException: The located assembly's manifest definition with name 'Interop.Word' does not match the assembly reference.
File name: "Interop.Word"
   at BuyersFund.FaxRequestWindowsService.ServiceProcessRequests.Bln_PrintAllFiles(String StrFileName, String network_printer)
   at BuyersFund.FaxRequestWindowsService.ServiceProcessRequests.PrintDocToNetworkPrinter(String TempFullDocPath, String PrinterName)

Fusion log follows:
=== Pre-bind state information ===
LOG: DisplayName = Interop.Word, Version=8.1.0.0, Culture=neutral, PublicKeyToken=null
 (Fully-specified)
LOG: Appbase = c:\puball\
LOG: Initial PrivatePath = NULL
Calling assembly : FaxRequestWindowsService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null.
===

LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind).
LOG: Post-policy reference: Interop.Word, Version=8.1.0.0, Culture=neutral, PublicKeyToken=null
LOG: Attempting download of new URL file:///c:/puball/Interop.Word.DLL.
WRN: Comparing the assembly name resulted in the mismatch: PUBLIC KEY TOKEN

There is a lot about this error message I do not understand.

Perhaps if I pick it apart one line at a time:



System.IO.FileLoadException:
The located assembly's manifest definition with name 'Interop.Word' does not match the assembly reference.
File name: "Interop.Word"
   at BuyersFund.FaxRequestWindowsService.ServiceProcessRequests.Bln_PrintAllFiles(String StrFileName, String network_printer)
   at BuyersFund.FaxRequestWindowsService.ServiceProcessRequests.PrintDocToNetworkPrinter(String TempFullDocPath, String PrinterName)


In the above error message, it says "the located assembly's manifest definition with name 'Interop.Word' does not match the assembly reference.

HOW is the assembly being located and it's manifest defnition being read?

WHAT is determining that that this manifest definition does not match the assembly reference?

WHAT is the assembly reference???????


I am so sooooo lost.....someone give me a clue.

Fusion log follows:
=== Pre-bind state information ===
LOG: DisplayName = Interop.Word, Version=8.1.0.0, Culture=neutral, PublicKeyToken=null
 (Fully-specified)
LOG: Appbase = c:\puball\
LOG: Initial PrivatePath = NULL

===

LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind).
LOG: Post-policy reference: Interop.Word, Version=8.1.0.0, Culture=neutral, PublicKeyToken=null
LOG: Attempting download of new URL file:///c:/puball/Interop.Word.DLL.
WRN: Comparing the assembly name resulted in the mismatch: PUBLIC KEY TOKEN



What is a fusion log?  Why is it called fusion?


LOG: Appbase = c:\puball\


I know what the puball folder is.      It is a folder that I made, into which I dump all of my solution's .EXE and .DLL files.


>>>>>>>>>LOG: Policy not being applied to reference at this time (private, custom, partial, or location-based assembly bind).


What POLICY is being referenced here?  Can I look at the POLICY?  Where is it?   What does it look like?  Should I change the POLICY, and how do I do it?



>>>>>>>>>LOG: Post-policy reference: Interop.Word, Version=8.1.0.0, Culture=neutral, PublicKeyToken=null


What is the significance of a Post-policy reference?  Does that mean there is a PRE Policy reference as well?



>>>>>>>>>>>>>LOG: Attempting download of new URL file:///c:/puball/Interop.Word.DLL.


Why is a download of this file being attempted and the file is coming FROM where and going TO WHAT FOLDER?


>>>>>>>>>>WRN: Comparing the assembly name resulted in the mismatch: PUBLIC KEY TOKEN


Okay, fine......why does this matter and how can I tell there is a mismatch?????

Was the Interop.Word generated when you added a COM reference to the Word type library?

the exception is thrown because the assembly found in appbase does not match the reference in your app - it has a strong name, while the reference does not specify a strong name for that reference.
try to remove the reference, add it again and rebuild the project.

I am psychic I guess.  Actually, that is the way that most people do it, and I just guessed :)

What version of Word are you using here?  I am guessing Word 2000.  If it is Word XP, though, there are Primary Interoperability Assemblies for XP that are better than auto-generated COM wrapper classes.
