Using testexecute command line with export log on html format

I play a suite with testexecute by a command line, and i want to export results with /el:FileName.html

"C:\Program Files (x86)\SmartBear\TestExecute 11\Bin\TestExecute.exe" "D:\CohorteV2\TestsAutomatiques\VlzTestApp-Supervision\VlzTestApp-Supervision.pjs" /r /e /SilentMode /elSmiley Very Happy:\TestsExecResults\Supervision_%_date%_%_time%.html

When my test is passed, i have a file.html but when i'm trying to open it, it is not html, it s text with a strange format like This
