XP・Does not start on Vista

 The code signing certificate used was GlobalSign until 0b168, but since then it has been changed to Certum.
 The signature of this code signing certificate cannot be verified because the root certificate (indicating the certificate authority) is not provided as standard on older OSes.
 Therefore, it is necessary to manually import the following root certificate into the OS as "Trusted Root Certification Authorities".

 readme/RootCertificate1-CTNCA.crt *XP,Vista
 readme/RootCertificate2-CTNCA2.cer *Newly required after 2023/12/20 (XP, Vista)

 Users of older OSes should check the content at their own discretion and import it manually.

 The common name of the signature has been " Gakuto Matsumura " since its inception in 2011.
 If you have any other signature, invalid signature, or no signature, please do not do so.

 0b178 Rev.18000 Up to DEV141 is the old certificate (Certum 2021-03-30). After that, the new certificate (Certum 2023-12-20) will be used.
 The updater is the old certificate up to 0.6.2023NS Rev.7. After that, it will be a new certificate.

 From the 0b180 generation, the official distribution and content of additional root certificates required for legacy OSs below Windows 7 are as follows.
