After a harddisk crash, I have lost my Sonar 8.5 LE installation file. I cannot download it anymore from the Cakewalk server. I still have the installation key.
Doen anybody have this file?

That's going to be a tough one to get. LE was the free version and that was almost 8 years ago.
Sonar Home studio I believe is only 50 bucks. That might be the way to go.
You'll get more plug ins and features than you had before and more importantly, you'll be up to date with the times.

Hi. I agree with Chuck. It will be hard to come by.
You get Sonar Home Studio with the December issue of Compure Music, which is even less than Sonar Home Studio alone. It also includes Rapture Session.

I bought (a year subscription) mine at https://zinio.com/www/browse/product.jsp?rf=sch&productId=500258045#/
This would as mentioned, bring you up to date.¨Hope it helps.
All the best.
 

Agree that's the best solution. LE versions, I have X1, are pretty lame. Home Studio is miles above my X1 LE version. 
You really don't want to fall to far behind. 
And I'm pretty sure your version was never a download it was a disk only.
