Solution to incorrect license file length


The solution to incorrect license file length is as follows:
During file transmission, certain software may filter spaces or characters in the license file, resulting in the length inconsistency between the current license file and the original license file. In this situation, the license file cannot be successfully activated.
1. In the user view on the device, run the dir command to check the length of the license file on the device.
2. In the storage location of the original license file, for example, PC, check the length of the license file.
3. Compare the lengths of two license files. If the length of the license file on the device is incorrect, upload the license file again. Generally, you can compress the license file and then transmit it to avoid this problem.
