Let’s have a summary of MRT registration. We can see from the above description that MRT is green software that can be directly extracted to run. That is, it can run in much operating system environment. You do not need to reinstall as long as the hardware environment remains unchanged. Moreover, different versions of MRT can coexist. For example, old and new versions of MRT software, if extracted to different folders, they can both be used. This is because the “installation” process does not actually exist in MRT application. The so-called installation program MrtSetup.exe is just a self-extracting package. You can change the suffix to MrtSetup.rar then open and unzip it with WinRar. It can still be used.
About registration. MRT needs to read MrtKey.txt when running, in which is the registration code. As long as the machine code does not change, you can keep using this registration code. That is to say, neither the software upgrade, nor reinstallation of operating system has influence on MRT. MRT just need to read MrtKey.txt. If you reinstalled MRT, you just need to put the file into the new installation folder as long as MrtKey.txt was backed up. It is very convenient. Users may have concern that what should they do if the former installation folder was deleted (that is to say, no copy of MrtKey.txt). It does not matter. User center automatically backups the most recent registration code. You can login user center website, select the "My Device" where all the serial number of all MRT products of the current user name are listed, then you can find the most recent registration code of this card by selecting "Query registration code". As is shown below:


As long as the hardware configuration of machine does not change, the machine code will not change, and the corresponding registration code can be used. Additionally, please note that, if the machine environment changes, the machine code will change, and the corresponding registration code will be permanently invalid. The user need to get a new registration code in user center even if the the hardware environment is recovered to the former. The former registration code cannot be used any more.
For example, MRT card used on host A, machine code is a, corresponding registration code is x
Then use this MRT card on host B, machine code is b. At this time, the original registration code x is permanently invalid. You need to get a new registration code. Assume the new registration code being y.
After a period of time, use this MRT card on host A. Please note that you cannot use the former registration code of host A, but need to get a new registration code.
These are the instructions of registration and activation.

Finally, after completing the registration and activation of MRT, MRT can be started normally. Up to this point, the installation MRT application is completed.
