Error loading fbclient.dll which is not a valid Win32 app #295

Closed pgfiore closed 1 year ago

pgfiore commented 1 year ago

Hi there, I hope everything is going well with you. I've just installed latest snapshot flamerobin-0.9.6-setup-x64 on a working 0.9.3.1bd8c1ac-setup-x64 (it's a WinServer 2019). The tool now fires an error while loading the win32 version of the fbclient.dll. Firebird is a plain installation: Firebird-2.5.9.27139_0_x64. And the C:\Program Files\Firebird\Firebird_2_5\WOW64\fbclient.dll is the original one and certainly a "win32" file too (as shown by the below image). image Could you kindly help? Ciao

@pgfiore Try FBCliente for x64

pgfiore commented 1 year ago

Thank you Jdochoa. I've overwritten the WOW64\FBClient.dll with the bin\FBClient.dll and it works like a charm. Do you mind if I ask why my x64 installation is looking in the WOW64 folder (which is the win32 one)?

Hello @pgfiore I'm not sure, but the windows look there.

Please close this issue ./jo

I'm not able to sort it out, but IMHO opinion, it sounds a bit weird. The error msg states that "it isn't a win32 app", but it's undoubtedly fake. The original FBClient on the WOW64 folder has proven to be a Win32 lib. The Flamerobin installation was done using the flamerobin-0.9.6-setup-x64, which should look for and load from x64 libs only. Furthermore, despite the name, the Windows on Windows (WOW64) folders are designated to file win32 libraries (it has something to do with the legacy "system32" name inherited from the old days).

In the end, it seems that x64 Flamerobin thinks of being an x32 app (and loading DLLs consequently)...
