Error setting up the openemr

I have been trying the installation of the openemr. I followed the steps and installed XAMPP. I get the first page after trying to reach my local host but when I try to move to step 1, I am getting the following error:
Not authorized (invalid csrf)

Unfortunately, you have not provided enough information for any suggestions. What OS is your local host? Since it is Xampp, I will assume Windows. Did you verify the XAMPP works by going to the default page? Did you configure these setting in PHP?

What are the correct PHP settings (can be found in the php.ini file)?

We recommend the following PHP setting, which can be set in the php.ini file (If you do modify this file, remember to restart your web server (usually Apache) to apply the new settings):

short_open_tag = Off

max_execution_time = 60

max_input_time = -1

max_input_vars = 3000

memory_limit = 512M

display_errors = Off

log_errors = On

post_max_size = 30M

file_uploads = On

upload_max_filesize = 30M

error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED

mysqli.allow_local_infile = On

Hello,

Yes I am in fact using a windows.
Where in the file to I paste these configuration?

Do I replace the whole file with the configuration?

I am very new to this, can you also let me know how to connect all the different desktops in the clinic to communicate with each other(Reception, consulting room, pharmacy).

I would really appreciate this.

Best,
