Hi Yuichi, I am trying to figure out what is going on here but my Japanese skills are a bit limited. Can you please share your MSI install log with me? This should be located here (note: it should be the newest log that matches this name pattern!):
Thank you for messages.
I dawnloaded MSI file form other PC and tried to install it.
I could install it.
???My PC's security setting is Problem???
I have never seen this problem before and would need more information to find a solution. I would need the installation log file (see above) and also your system specifications.
