selenium Builder playback Problem

[SwathiRajRapaka]

Dear Selenium Builder Lovers,

One small help.

I am a newbie for Selenium Builder. Don’t mind

I am using Firefox V55, selenium builder V3.1.2 and I am using the jar for running the server is
selenium-server-standalone-3.4.0.

My problem is that I am able to record the scenario successfully but when I try to playback it is giving me the below mentioned error and not allowing me to proceed further in builder. I need explicitly run my scenario’s once again in the builder itself.

Server Error: Server Error: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: VISTA Build info: version: '3.4.0', revision: 'unknown', time: 'unknown' System info: host: 'HYDHTC284703D', ip: '172.21.247.61', os.name: 'Windows 7', os.arch: 'x86', os.

I checked with my system variable they are configured properly.

Anything needs to be done in configuration part in the tool.

Help would be appreciated in this concern.

Regards,
Swathi.
