VS2005 Office add-in (no VSTO) -which framework required for end u

[alejandro.campos]

Hello,

I'm developing a VS 2005 shared COM add-in for Excel. I've run into this
issue when deploying it into some machines. If that machine has the .NET
framework 2.0 everything is all right . If the machine has versions 3.0 or
3.5, I have to install version 2.0 and explicitly tell Excel to use it
instead of the other ones (copying this Excel.exe.config file to the
Microsoft Office directory); otherwise it won't load. Even if I have .NET 2.0
and 3.5 installed and I tell Excel to use .NET 3.5, the add-in won't load at
all.

Do you know why's that? Is it a requirement that the end user has .NET 2.0
when you develop the add-in with VS 2005 (that uses .NET 2.0). Are .NET
3.0/3.5 not backward compatible?

Thanks

Hello Alejandro,

You don't need to install .NET Framework 2.0 on a PC, on which .NET
Framework 3.0 (or higher) is installed because 3.0 and 3.5 are just
additions to 2.0.

otherwise it won't load.

Did you check this? If yes, then it is possible that another add-in or smart
tag uses 1.1 and prevents your add-in form loading.
