Advanced Tip: Version Compatibility Matters

Iolo offers different tiers:

• System Mechanic (basic)
• System Mechanic Pro
• Ultimate Defense

👉 If your license doesn’t match the installed version, activation will fail.

Always install the correct version linked to your purchase.

Security Note (Important)

Activate only through:

• Official System Mechanic software

Avoid third-party activation tools or shared keys. These can cause license errors or security risks.
