I wish there was a way I could get 10.6
I had 11.4 but deleted it after getting 11.5
Someone on this thread will have the .exe file saved in their download folder. I will check mine, but I'm pretty sure I deleted everything in my download folder a few weeks ago.
If I were you, I'd just email them and ask them to send you the file. As a customer, you should have the right to use an existing product.
