I have update IpcName in firebird.conf to

IpcName = Global\FirebirdIPI


I also restart my Firebird 1.5 application (I run as application) but it doesn't work. I still get "unavailable database"

My database is located in my document folder.

I am using SuperServer.

Please note that I am using Windows 7 64 bits. I am not sure if 64 bits windows has any issue with Firebird 1.5.

Just for your information, I can connect to Firebird 2.1 in Windows 7 64 bits using local connection string without any problem.
