I have successfully installed and used a wallet under Windows 7. In addition to the 2 copies of the blockchain discussed previously I noticed that by default both the blockchain database files and the user's wallet data files are stored in the user's roaming profile C:\users\%USER%\AppData\Roaming\Armory\. The same is true for the underlying Bitcoin-qt client.

This causes a fairly big problem if you log onto a domain with a Windows profile server and roaming profiles enabled on your Windows account since Windows tries to sync 2 x 18Gb of the blockchain DB files between the PC and profile server when you log on / off.

To prevent this, I have used the datadir command line options to move both the blockchain DB files and the wallet data files for the watch-only installation to the local profile, C:\users\%USER%\AppData\Local\Armory\. Windows then still "protects" the data from being seen by any other users.

However, I think better practice would be for the wallet data files to be stored in the roaming profile, and hence backed up, and the blockchain DB files stored in the local profile since this data is re-creatable. Is there a way to do this? I.e. separately specify where the blockchain DB goes and also where the wallet data files go?

BTW Looking forward to the new light versions.
