I would suggest unsupervised learning like Clustering. That would be my go-to because it is quick, and also easy to explain.
If you want to try more advanced things, Andrew Cathie has presented papers recently at SAS Global Forum on using the outputs of decision trees and regressions to solve the curse of dimensionality. Links to his papers:
The Anti-Curse: Creating an Extension to SAS® Enterprise Miner™ Using PROC ARBORETUM

I hope it helps,
