New Post: Assemblies not added to GAC

I've done a deploy using the MSI on three servers

First two just ran the MSI, third one the full install + deploy

But found that in the first two servers, whilst the file were copied to Programs Files, they weren't added to the GAC !

I had to use GACUTIL to get them in

Any idea what I've missed / messed up ?

Cheers,
SteveC.
