Hi
I use 6.3 version of Packet Tracer and I;m trying to setup static routing between 3 routers
I setup all static routing in all 3 routers but it doesn't work
I attached pkt in zip and also screenshot files so you can trace my settings.
What is wrong there?

Hello Artur,
for static routes to work the routers must share a common IP subnet.
In your network diagram the link RT1 - RT2 the listed IP addresses 200.20.0.1 on RT1 and 200.20.1.1 on RT2 are on the same subnet are you using a network mask 255.255.254.0 = /23 ?
Check IP ARP entries with
show ip arp 200.20.1.1 on RT1 and
show ip arp 200.20.0.1 on RT2
Only if they are in the same IP subnet the ARP entries are popoluted
Hope to help

Hello Artur,
use the following in privilege mode 15
show ip arp | include 200.20.1.1
However, your issue is exactly what I have written before:
>> RT1 200.20.0.1/24 and RT2 200.20.1.1/24 are NOT in the same IP subnet.
This breaks the IP connectivity end to end.
On RT2 change to
ip address 200.20.0.2 255.255.255.0
change the static route on RT1 accordingly as follows:
ip route 192.168.20.64 255.255.255.192 200.20.0.2
Because I have seen you are using netmask 255.255.255.0 = /24
Hope to help

This is a puzzle, where to where are you trying to connect? IP;s please clarify and do your traceroutes and give us more detailed info.
cheers
