Possibly an old 32-bit client somewhere in the system path?

A manual install requires running instreg.exe from the root directory of the new installation, e.g., (in the rootdir) bin\instreg.exe)
- followed by instsvc to install the service. In the bin dir, run instsvc.exe to get help with the parameters.

AFAIK, the installer doesn't install the version string from the executables anywhere in the Registry. My guess is it has found an old client in the system path. Find that, check the version number on the prop sheet and rename it to something obscure to disable it. Then, from the bin directory beneath the rootdir, run instclient.exe to install the client you want, where you want it. Again, run instclient.exe with no params for help with the params.

If you are using 32-bit Flamerobin, you will need the 32-bit fbclient.dll. Eyes out for the appropriate MSVC8 runtimes, as well. If you need a 32-bit client, you'll need the 32-bit MCSVC8 runtime assembly. The 64-bit server needs the 64-bit MSVC8 runtimes so also check that you have those available.
