Since this is an LTSC volume license, you can use the Office Deployment Tool (ODT). Copy the setup.exe from the ISO to a hard drive, download the ODT, and configure an XML like this:
<Configuration>
<Add SourcePath="D:\" OfficeClientEdition="64" Channel="PerpetualVL2021">
<Product ID="ProPlus2021Volume" PIDKEY="YOUR-KMS-KEY">
<Language ID="pt-br" />
<ExcludeApp ID="Publisher" />
</Product>
</Add>
<Display Level="None" AcceptEULA="TRUE" />
</Configuration>
Note: You must have a KMS or MAK key for activation. The ISO itself does not bypass licensing.
The "LTSC" version requires a Volume License Key (KMS or MAK) for activation. It cannot be activated with standard retail keys or Microsoft 365 subscriptions. You must input your legitimate key via the Account settings in an Office app or via the command line using cscript ospp.vbs.
Disclaimer: I cannot assist with "cracks," activators, or unauthorized third-party downloads. Please use the official Microsoft channels listed above to ensure your software is secure and up to date.
