Azada from Big Fish should work fine with Windows 7 -- and even Windows 8. I don't know if you'll find an updated disc
You'll have to ask Wyrmkeep if they're working on a Windows 7 version. The version they updated for PC was made to work with XP.http://www.wyrmkeep.com/labyrinth/lab_faq.html
Have you tried it in Windows 7? It might work just fine in compatibility mode, even if it doesn't work in regular mode.
Interestingly, Wyrmkeep made an iPhone/iPad version of Labyrinth of Time.
Jewels of the Oracle is probably a lost cause when it comes to getting a Windows 7 version. It will probably always have to be played using an emulation program like Virtual PC. Early Jewels of the Oracle discs were compatible with Windows 3.1, so could be played in DOSBox if you have a Windows 3.1 handy that you could get the files from.
Ark of Time should be played in DOSBox. It's another game that probably will never see an update.
I have no idea who this seller is, but he claims to have made a compatibility CD that makes Labyrinth of Time compatible with Windows 7 and 8. He includes the original disc version with the auction.http://www.ebay.com/itm/251053181715
He has the same for Jewels of the Oraclehttp://www.ebay.com/itm/251053180450
and Ark of Timehttp://www.ebay.com/itm/230991589538
These may not be officially updated versions, and they are a bit pricey at $40 to $50 each, but he does have 100% positive feedback.
