What have you done in place of Encore??

I know this topic has been discussed over and over but 1) I've searched the forums and have not found a suitable answer and 2) despite my searching there's still about a zillon posts on this subject so it's like chasing my own tail! lol

Bottom line, I know there's a lot of us in the same boat where we updated our Mac OS to Big Sur and now Encore doesn't work.  I was able to boot my computer in Mojave only to learn that Adobe CS4/5/6 (and hence Encore) CANNOT be downloaded.  

Please help me out, what have you all done in this case?  Like others, I have multiple clients breathing down my neck to get their discs and I don't know what to do.  There's some talk of other software programs but I can't seem to make heads or tails out of all of it.

I GREATLY appreicate any feedback or advice.  

Question - do you know if it is possible to get Encore app files from a colleague and install it on my computer??

THANK YOU!

Eric
