Finding Serial Number on my PC

[MorteDeAngelis]

Greetings

I've recently been getting an Error 6 code when trying to launch PS CS4 on my computer. I recently upgraded to Win 10 from Win 7 and ever since I change the HDD CS4 was on I'm unable to laucnh it.  This is the same as all the other adobe programs within the CS4 Master Collection.

I've been trying to look for the disks to be able to re-install the Master Collection however, I've been unable to find them.  So I've borrowed I found a friend who had the same CD's so I can re-install but I don't know the serial number that was used. 

I've looked around and found that you can get a encrypted number in the Registry of windows does anyone know who I should try and contact to get the number decrypted or any where else I might be able to look to find the serial number that is currently active on my Photoshop?

First, that software is old enough that it may not work at all with Windows 10... but

An idea that MAY work to install and/or run old programs in Windows 10
