While 64-bit allows huge imports, do not import every row. Use Query Folding in Power Query to let the source database (SQL) do the heavy lifting, then import the aggregated result into your 64-bit model.

Power invites responsibility. The capacity to load massive datasets should not translate into careless models. Thoughtful design still matters: clean data modeling, careful use of relationships, judicious column selection, and optimized DAX remain essential. The 64-bit environment encourages experimentation, but good governance—clear naming, version control, and performance testing—preserves reuse and trust. Put simply: power without discipline breeds fragile reports; power with discipline yields durable insights.

Warning: Avoid third-party “cracked” or “portable” versions. Power BI is free for desktop use; downloading from unauthorized sources is a security risk.

The "full" designation implies that you are not using the Microsoft Store "sandboxed" version or a limited web installer. You want the standalone, fully featured executable that installs:

Who needs 64-bit? Anyone working with log files, SQL Server data warehouses, or industry-specific data (like IoT sensor data or financial transaction logs). If your data exceeds 500MB in the model, do not install 32-bit.
