The solution is the following:
When XE3 installs, it installs Interbase for XE3, and a GDS32.dll to the SysWOW64 folder.
Uninstalling Interbase for XE3 did not remove this dll
Reinstalling FB did not overwrite this .dll
Removing it manually, then re-installing FB again got all up and running.

Hope this can help someone else.
Perhaps someone more versed at this can explain a workaround keeping Interbase for XE3 on the system.

Thanks

Subject: [IBO] Unavailable database after installing Delphi XE3, and IBO 5.2


Hi,

I noticed that after installing XE3, and installing latest sources of IBO, and getting all to compile that I could no longer connect to my databases, using my apps, some compiled with Delphi XE.

I then removed the interbase XE3 from my PC.

I can connect using a third part SQL tool to my databases, but not using IBO, even with my previous versions of software compiled with XE.

I reinstalled FB 2.5.2.26539
I checked that service is running in services manager Win7 64 bit.

When I try to log on to any application I get:
ISC ERROR CODE: 335544375, Unavailable database.

All the databases are there.
The service is running.

Any ideas what could have destroyed all that was working up to installing XE3, and Interbase support that gets installed by default.
I have removed the interbase for XE3 from my system.

When trying to connect to my remote server with my software also written with Delphi XE, and IBO, the remote host refuses the connection, but I can connect to it using my SQL tool.
ISC ERROR CODE: 335544421, connection rejected by remote interface.

Thanks

Adrian
