I have an assembly whose Win32 file version is higher than the one I have installed. The Assembly versions are still the same. If I use Gacutil I can install the new version over my previous version since the FileVersion is higher. However MSI doesnot go by the File Version, they go by the AssemblyVersion. Since the AssemblyVersion are still the same, they don;t install over the old one. I found an article on Microsoft site which says this is possible. Here is the link :

Can anyone let me know How can I specify the Win32 file version on Assembly table?

I found the solution to this problem:

If I set the FileVersion to the WIN32 File Version on the MsiAssemblyName
table then MSI will replace the Assembly on the GAC even though they have the
same Assembly Version. I did a test and it seems to work.

You need to set the FileVersion attribute to the Win32 File version of the assembly.

Here is how my MsiAssemblyName table looks:

Component1       Name                        MyComponent
Component1       Version                       1.0.0.0
Component1       PublicKeyToken         abcdefghijkl
Component1       FileVersion                  100.0.0.0
Component1       Culture                         neutral
