PLEASE HELP ME

I need your support.

Thanks...

Send that error message to your host, it's an mbstring error and they should correct the server settings for you.

c:\appserv\www\dolphin\install\index.php on line 541

since you are running a home server, there is no host for you to contact, so you will need to recompile php with mbstring enabled to run dolphin. since this most likely is not possible on a windows machine, you will need to read some documentation that will take you through the process of doing this within httpd.conf or reading your htdocs. good luck.
