I use windows 10 from 3 months I not getting any installation error but i get my window slower it is not an issu.
so your problem is to installing dreamweaver software i suggest you following steps follow .
1. Cheque your system configuration 64 or 32 bit when your system is 64 bit then you install your programs have 64 bit only
2. If ti is 32 then you install 32 bit configuration software.
If it is not work then run disk cleanup and ccleaner and uninstall unnecessary software and try install your software .
