// Installation Notes //
for v4.4.12 on Windows:

Uninstall all previous versions of Pix4Dmapper very cleanly (using tools like Total Unisntall), including all files, folders and registry keys
Install ‘Pix4Dmapper_4.4.12.msi‘
Run patch ‘HWID.exe‘
Find your PC/device name from “Control Panel\All Control Panel Items\System\“, type it to the “Enter Owner value” field in patch, click ‘Generate HWID‘, and copy the generated HWID
Run ‘4D-Permit-4X.exe‘, paste the HWID, and click ‘Decode‘
Change the “Days” value from 1 to 9999, and click ‘Save REG‘
Double click the generated reg key file to import license info
Copy the unlocked file ‘version.dll‘ to installation folder (it’s used to block Pix4Dmapper from connecting to the Internet); Or, you can also use the ‘Pix4DTool.exe‘ instead (***)
Then you may need to sigh out/log off/restart to make the registry change take effect
Done
*** The Pix4D Tool realizes the purpose of disconnecting Internet by modifying DNS. You need to restore the DNS setting after exiting this tool. Some helpful CMD commands are as follows:

ipconfig /flushdns (Free DNS Cache)
ipconfig /registerdns (DNS Registering)
ipconfig /release (IP Release)
ipconfig /renew (IP Renewing)
netsh winsock reset (DNS Socket Reset)
