The HWID matches, so the key is valid for your machine. From the screenshot both the Registration name and License key fields are still empty, that's why it isn't taking.

Fill it in exactly like this:

Registration name: h3x4
License key: ACVlNDFlOTI1Yzc2NmNiZWUxOWI1MzdhOWQ0M2JjNWI1OXxoM3g0MEYCIQC7KkmsNkBn2STLTbDm4cnL-l49w1cyzKwWimhSwmWnSwIhAKX5tHKtHTEMEQylf3p4Pl9JGcCpH5ZDpVUY5QKZ8J

Copy the whole key in one go with no spaces or line breaks, type the name lowercase exactly as h3x4, then run the program as administrator and click OK. If it still refuses after that, post a new screenshot with both fields filled so I can see what it shows.

same problem

I can read the key in your new screenshot and it's still the corrupted version. It shows:

Code:

ACVlNDFlOTI1Yzc2Nm...4cnL-l49w1cyzKwWimhSwmWnSwIhAKX_5tHKtHTEMEQylf3p4Pl9JGcCpH5ZDpVU_Y5QKZ8J

Wait — looking more carefully at the field text in the image, the start still reads ACVlNDFlOTI1... but the middle/end has extra characters compared to what I posted. The paste is picking up leftover text or you're pasting on top of the old string instead of replacing it.

Do this cleanly:

Click inside the License key box and press Ctrl+A then Delete to fully clear it. Confirm the box is completely empty first.
Do the same in the Registration name box, then type h3x4 fresh.
Now paste only this, nothing before or after:

Code:

ACVlNDFlOTI1Yzc2NmNiZWUxOWI1MzdhOWQ0M2JjNWI1OXxoM3g0MEYCIQC7KkmsNkBn2STLTbDm4cnL-l49w1cyzKwWimhSwmWnSwIhAKX_5tHKtHTEMEQylf3p4Pl9JGcCpH5ZDpVU_Y5QKZ8J

The key must start with ACVlNDFl (lowercase L, then N-D-F-lowercase-L) and end at Y5QKZ8J — nothing after it.

If after a clean clear + paste it still blanks on OK, take one more screenshot right before clicking OK so I can confirm the exact string in the box character by character.

The key is tied to the HWID you posted, so it should match. When it won't register, it's almost always the paste, not the key.

Try this once cleanly:

Click inside the License key box, press Ctrl+A then Delete so it's fully empty.
Type the name as kirolsan in lowercase, no spaces.
Paste only this string, nothing before or after:

Code:

ACk1ZWRlZmQ3ZWNmODk1ZGQ1NzBiYTQ4ZGVhYTRjNDIzM3xraXJvbHNhbjBEAiBCtP-iLOP-Q4YExXNV0TC5nonWkzIdkVCTd5kbAfn5rwIgfcWvTUTG4eiCMezOGMyiPzBmoVNF-Aca7FIBHsyaHv4=

It ends with = and has underscores in it (…tP-iLOP-… and …NF-Aca…) — make sure those survive the paste. Run the exe as administrator first, otherwise it can fail to save silently.

If it still refuses, post a screenshot with both fields filled right before you click OK, and confirm the exact error message so I can see what the program is receiving.

Where did you download the program from, go there and request the license from them. I have everything.

Hola Ricardo. La clave está generada para tu HWID 9D80-379D-5532-5966-2956-B3F1-694C-29CA-68, así que en principio corresponde a tu equipo. Cuando no activa, casi siempre es cosa del pegado, no de la clave.

Prueba esto una vez, con calma:

Haz clic dentro del campo License key, pulsa Ctrl+A y luego Supr para vaciarlo por completo. Confirma que quede totalmente vacío.
En el campo Registration name escribe ricardo101 en minúsculas, sin espacios.
Pega solo esta cadena, nada antes ni después:

Code:

ACs5ZDgwMzc5ZDU1MzI1OTY2Mjk1NmIzZjE2OTRjMjljYXxyaWNhcmRvMTAxMEQCIA3VizdUTx7TNqZQ89ak7O3QLLiZ2qvMnY-YeEJiZFqcAiB2LD2WTI7561Pd8Q8kwFPJAg35PUeyLRmsFueA2yLFoA==

Termina en == y lleva guiones dentro (…nY-Ye… y …2yLFoA==). Asegúrate de que esos caracteres sobrevivan al pegado y que no se cuele ningún espacio ni salto de línea. Ejecuta el programa como administrador antes de registrar, si no a veces falla al guardar sin avisar.

Si aun así no la acepta, dime el mensaje de error exacto que muestra y pon una captura con los dos campos rellenos justo antes de darle a OK, para ver qué está recibiendo el programa.
