[SOLVED] Firebird 5 remote login via app on Windows 10/11 DLL file/s
error

Logging in via the app raised dll file error about failing to load
'fbclient.ddl or gds32.dll or fbembedded.dll' even though the
'fbclient.dll' was in the program folder. This error got raised
because Microsoft C/C++ runtime libraries were not installed. I solved
it by installing the relevant package found on

https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-
redist?view=msvc-170

If someone knows how to include the package install file and
automatically run it in the setup (created using Inno Setup) during
installation or to prompt the user to download and install it either
before the app installs or after installation I would greatly
appreciate it.

May be "Sakkie" is asking how to include VCRT installation in his
application Inno Setup?
Then inspiration can be taken from Firebird Inno Setup as pointed out
by "ttomas"

I have no problem connecting to FB5.

In fact, client still using FB3 to connect to FB5 server.

Just put fbclient.dll and msvcs100.dll in the same folder of your exe
file and make sure that your app use this dll. This worked for client
with FB3.

Thank you so much. I am going to use this example for my setup.

Initially, I did put both of those DLLs but the error didn't go away.
Anyway, I am going to use what ttomas posted as a guide.
