Although the free office activator 2025 is highly reliable, some users may encounter typical problems.:
The antivirus blocks the program. The solution is to add the KMS Tool to the exceptions or temporarily disable protection.
Office activation error – Often occurs due to applications that are not closed. Close Word/Excel and try again.
Activation resets after reboot – The problem may be related to the remnants of previous licenses. Use the "Clear License" feature in the KMS Tool.
My Windows version is not supported. Make sure you are using the latest version of the KMS Tool from the official website.
For complex cases, the KVS Tool has a built-in error Log that helps pinpoint the cause of the problem. Most issues are resolved by updating the program or reactivating it with a pre-cleaning of the system.
