Is there a way to import an application exported from Appian 6.6.1and import in

The import log confirms what Myles and I said; this is not supported because some features are not compatible with previous versions, if you see your import log, you have two problems; the first one is the target envrionment doesn't have a primary data soruce configured, and second, data stores from 6.6.1 are internally different from 6.6.1 therefore they are not importable into an old version of Appian. Please use an installation of 6.6.1 instead.
