Procedure when using a virtual environment such as VMWare or VirtualBox

1. Install the following OS on the created virtual machine. Windows 10 version 2004 (official name Windows 10 May 2020 Update)
   • We are only validating this Windows 10 version. Depending on the OS version, there was a report that "whitelist setting does not take effect" depending on the version of the included Flash Player plug-in.
   • It is expected that newer versions than the above will not include the Flash Player plug-in itself.
2. Please stop the OS update.
   Eliminates the possibility that the Flash Player itself will be deleted or its operation will be suppressed by updating the OS.
3. Set the whitelist of Flash Player.
   1. Create mms.cfg in the directory that matches your browser. IE is a browser that can be used in the initial state of the built virtual machine environment and meets the system requirements of intra-mart Accel Platform.
      When using Flash Player with IE on Windows 64-bit OS, create mms.cfg in the following directory.
      If the directory does not exist or the file does not exist, create it. % windir% \ SysWOW64 \ Macromed \ Flash \ mms.cfg

   2. Set as follows in the created mms.cfg.
      
      EOLUninstallDisable = 1 EnableAllowList = 1 AllowListPreview = 1 AllowListUrlPattern = https://example1.com/imart/ AllowListUrlPattern = https://example2.com/imart/

      1 2 3 4 5

      EOLUninstallDisable=1 EnableAllowList=1 AllowListPreview=1 AllowListUrlPattern=https://example1.com/imart/ AllowListUrlPattern=https://example2.com/imart/

      EOLUninstallDisable = 1	Hide the prompt to uninstall Flash.
      EnableAllowList = 1	Make the whitelist available.
      AllowListPreview = 1	Does not apply to AllowListUrlPattern and logs blocked requests with trace ().
      AllowListUrlPattern = https://example.com/imart/	Add the prefix URL to the whitelist. Multiple settings are possible.

   3. After restarting the browser, access the screen that requires Flash Player such as the query edit screen, and check that the screen is displayed.

   4. After confirming normal operation, take a snapshot of the virtual environment.

If something goes wrong with the virtual machine you built, you can restore it to the state it was in when you took the snapshot.
It is expected to be an effective countermeasure when the operation of the OS or middleware has changed or when there is a risk of being infected with malware.
