>>We have some problem with gds32.dll that it installed on my pc. It doesn't work with firebird 2.1.x

Thanks for the heads up, Interbase seems to be getting more popular again. I found have IB services running on my PC, and I have no idea what software put it there! What error message do you get, so we can look out for the problem on our older versions that used to use GDS32.dll, instead of FBClient.dll?
