### Guidance for the first time

Displays a guidance dialog for beginners. This is the same as what you see when you first launch Metasequoia.

If you check [Show this guidance again at the next start] on the lower left, this guidance will be displayed when you restart the software.

### About

It shows the version or the copyright of Metasequoia.

### About Plug-ins

It shows the information on Plug-ins and installs the new Plug-ins.

### Error Window

It shows error messages in case the illegal Plug-ins is read or some error has occurred.

### Benchmark

It measures the number of drawing sheets per second.

It can confirm which set-up makes a faster view. As the measuring is not so accurate, it is not so effective to use for the comparison with that of other hardware.

### Official web site metaseq.net

It displays the official web site metaseq.net.

### Update check

It checks update information from the Internet.

### License authentication

It inputs a serial ID and password that you purchased. It is necessary for removing restrictions on operation.

Please confirm the following items if the license authentication fails:

- Please confirm each character; like '0' and 'O'.
- Administrator authentication may be required. Please run Metasequoia by [Run as Administrator] in the right-click menu on a start menu or a desktop icon.
- Security software may disturb the license authentication. Please switch it off temporarily.
- A license for Metasequoia 4 is required. A license for old versions of Metasequoia is not available. Please purchase a license for version up.
