Fireworks problems

So yes, I'm still using Fireworks. My old computer has cs6 installed. Now I'm trying to install on a new computer. I don't have the discs but have gotten it thru creative cloud. 

1) accessed products and there is a separate serial number for cs 5 suite

2) that actually comes with download links

3) that download does not fully install

4) still have the old computer with working copy

5) I don't see the serial number anywhere

6) installed various downloads of cs5 and cs6

7) pay for creative cloud monthly for years!!!!!

My business has used this all along. I have paid for these products since 2006. I want fireworks. I know it works on windows 11 cause it did on mac/parallels.  I understand adobe does not want to support old products but considering the amount of money I have put out since 2006? Seriously folks. 

Now what?
