Need for "password" in order to unzip purchased extension

Good day!

I’ve just purchased an extension from your Store (DrawerArrangement).
Got the .zip file OK.
But when I tried to unzip it a message popped-up: “…I need to enter the same encryption password as when the file was encrypted…” or something to the same effect.
Can somebody help me to solve this issue, please?
Thanks in advance!

P.S.: tried to send an email to sales@inventor.life twice regarding the above but “it could not be delivered”…(?)

Que tal Daniel, realicé la compra de la extensión MQTT TCP/IP, ¿Porqué medio te llegó el archivo .aix?. ¿Como resolviste tu problema de la contraseña del .zip?, gracias
