Help needed! MySqlInstanceConfig.exe references to a non-existent mysqld-nt.exe

[Denis Esteban]

HI everybody. I am trying to make a batch file .bat to configure MySql 5.1.54 in Windwos 7.
This is the command:

c:\mysql>MySQLInstanceConfig.exe -i -q "-lC:\mysql\install_log.txt" "-nMySQL Server 5.1" "-pC:\mysql\Install" -v5.1 "-tC:\mysql\install\my-small.ini" "-cC:\mysql\mytest.ini" ServerType=DEVELOPMENT DatabaseType=MIXED ConnectionUsage=DSS Port=3306 ServiceName=MYSQLCust RootPassword=fernando AddBinToPath=yes

But, the service doesn´t star because the command file (when seen in the service properties in the service administration window of Windows 7) is the following:
"C:\mysql\Install\bin\mysqld-nt" --defaults-file="C:\mysql\mytest.ini" MYSQLCust
The log file shows exactly the same:

Parameters: "C:\mysql\Install\bin\mysqld-nt" --defaults-file="C:\mysql\mytest.ini" MYSQLCust
Cannot create Windows service for MYSQLCust. Error: 0

But, the mysqld-nt.exe is not in the bin folder of MySql 5.1.54 because it was removed since 5.1. So, it obviously won´t run, because the file to be referenced to is mysqld.exe instead of mysqld-nt.exe.
How can I make the MySqlInstallConfig.exe references to mysqld.exe and not mysqld-nt.exe when creating the service? I think it is a bug, because the very developers removed the mysqld-nt program. In fact, I found it was a bug in 5.0 solved in 5.1, but in my case it is not solved. The strange fact is that if I open visually the mysqlinstallconfig.exe and use its windows to configure mysql server, it works.
I have tried with the mysqlinstallconfig.exe of the versions 5.1 and 5.5, 32 and 64 bits, and it is the same, nothing changes.
Thanks in advance.
