Yikes! It looks like the local AppData directory name is so long that installing the NH designer underneath it is resulting in file paths longer than the OS allows. What's your local AppData path (e.g. C:\Users\Ivan\AppData\Local)?

Hmm, Windows XP does use longer paths for app data (C:\Documents and Settings\user_name\Application Data...) but even then it shouldn't be an issue unless your user name is more than about 30 characters. Is that the case for you? Or is your local app data path remapped to a server or something like that?

My path is:

C:\Documents and Settings\Administratör\Lokala inställningar\Application Data

No server mapping, it's a local path.

Pretty long, but is it long enough to cause problems?

It shouldn't be long enough to cause a problem, but on investigation it turns out Visual Studio is creating a file named (on my machine):

C:\Users\Ivan\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\Mindscape\Mindscape NHibernate Model Designer\2.0.316.20269\package\services\digital-signature\xml-signature\7ccc824f539e437295568fd5635fd8d9.psdsxs

and with your longer LocalAppData path that is enough to put it over the top by about six characters.

Unfortunately, this file is out of our control (except for the product name and build number) so I'm not sure what to recommend. It may be possible to change your Local Application Data path (or even your whole profile path, to shorten that "Documents and Settings' bit), but this feels like a sledgehammer to crack a nut.

I've successfully installed now by relocating LocalAppData to C:\Temp\Local using a registry hack. Thanks!

I have exactly the same issue, I sent an email to the after sales service about this. Waiting for their answer, how did you manage to change the path of the AppData. I'm on Windows SP3 as well (32bits). And I'm afraid not being as good as you with the registery ^^.

Have a look at http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q236621 for details about how to move the Documents and Settings folder, in particular read down to the section which details how to move this after installation (the section beginning with: To specify a different folder for the "Documents and Settings" folder after you install Windows for a particular user, follow these steps)

You will want to be comfortable with what it is describing before proceeding with any change!
