OK, here's the story.

The addin wasn't located in
"C:\Program Files\Mere Mortals .NET Framework 2005 \MMBusinessLayerGenerator\MMBusinessLayerGenerator.Addin"

instead it was located in
"C:\Program Files\Mere Mortals .NET Framework 2005
\MMBusinessLayerGenerator\MMBusinessLayerGenerator
\MMBusinessLayerGenerator.Addin"

There seems to be two "\MMBusinessLayerGenerator" directories. It looks like all the source code is in this second subdirectory.

However the "MMBusinessLayerGenerator.dll" was located in both
"C:\Program Files\Mere Mortals .NET Framework 2005\MMBusinessLayerGenerator\MMBusinessLayerGenerator.Addin"
and in
"C:\Program Files\Mere Mortals .NET Framework 2005
\MMBusinessLayerGenerator\MMBusinessLayerGenerator
\MMBusinessLayerGenerator.Addin"

I was having other problems with SQL Server and VS 2005 so I had to reinstall them, and I finally did see the addin in the "Add-In Manager..." menu.

When I went to add the addin, I got the message that the specified file couldn't be found. The addin file was located in
"C:Documents and Settings\All Users\Application Data
\Microsoft\MSEnvShared\AddIns"
and when I opened it and looked at it, it seems to have been an old file that pointed to the "E:\" drive where I had put your program before.

After copying the new addin file to this location, everything worked again.

So, maybe the re-installation didn't put the files in the correct directories?

Thanks.
