Hi,  
I know fpmi is not officially supported under vista, but…is there a java guru here whoa can explain why i cannot connect to the designer ?

below is the error code :

`java.net.MalformedURLException: For input string: "0:0:0:0:100:7f:fffe:8080"

`

It seems tha the problem come from the ip adress format “0:0:0:0:100:7f:fffe:8080”

Thanks,

😃 I’ve the solution.

The problem is the new IPV6 stack wich is activated by default.  
To deactivate it, you must create new key in the registry :

`HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]
"DisabledComponents"=dword:000000ff
`

This diable ALL ipv6 and prfer IPV4.

Software team, please take this in account for next release.
