There is a single installation for both the free and paid version, with the free version converted to the professional version on entering the key for the product. The software is surprisingly very small measuring just 12 MB. I got in contact with NUIBI and they were nice enough to give me a key for their professional version of the software.

These are tall claims and though they promise a 90-day return warranty, I intend to check out the authenticity of their claims. It comes with Built-in Roll-Back Protection technology that claims to rollback the changes you are doing through the software in case of any software or hardware issue within 1 second and with 100% data security. The name of this software is NUIBI Partition Editor. However, recently I have stumbled upon a partition manager that claims to protect our computer drives from such dangers and rollbacks the computer to the previous state within a second. I have reviewed a lot of such partition managers in the past like the EaseUS Partition Master Free 10.5, MiniTool Partition Wizard, Paragon Partition Manager and many other such partition managers. The danger of any interruption like power failure can lead to the whole hard drive becoming unusable. Partitioning your hard drives is always a risky affair.
