Smart Bear Test Complete says it has an update waiting I let it run the update and it fails ugly Smart Bear Test Complete never runs again. Dead installation. Totally unusable. The help I find says to start some service that apparently was removed by the failed update I try rerunning the installer and it says I have a newer version already installed and quits. Should I ask for a refund? Re: how to fix Sentinel Runtime Environment installer failed unable to install an inf file What if the installation that killed the service was an automatic update that failed and now you can't get it to run again?
