​​Special instructions:

Reasons why the software crashes when running:

​ ​ 1. Some new computer CPUs use the AES-NI instruction set which relies on the OpenSSL library and is different from the old version: such as Intel 10th Gen (Ice Lake) CPUs or newer (11th Gen (Rocket Lake), 12th Gen (Alder Lake), 13th Gen (Raptor Lake) etc.

Solution:

Right-click "This Computer"-"Advanced System Settings="Environment Variables="

The new variable is named "OPENSSL_ia32cap" and the value is: "~0x200000200000000"

Or you can try to install OpenSSL

​​ 2. Some system reasons may require you to change the program file name to English or numbers.

​​The problem of error when decompressing after downloading:

The software uses WINRAR 5.31 for compression. If your decompression software version is too old, decompression may report an error and you need to upgrade your decompression software.

1: Brand new interface, refreshing, simple and efficient

2: Performance is getting better and better
