Note that for a 32 bit application, you need to 32 bit fbclient.dll. It
might be better to expect it on the path. But otherwise: follow the MSDN
links: it describes how to locate 64 bit registry keys as a 32 bit
application. Note that editing aliases.conf also requires privilege
elevation if UAC is enabled.

I can't be more detailed as I don't usually work with the registry (nor
work with fbclient.dll).

Mark

Yes I did find out the need for a 32 bit FBClient.dll so that is good, I have added it to the application folder.

Thanks, the links did help and I was able to get to the 62 bit hive using RegOpenKeyEx() command from a 32 bit app.

Kind regards
