["Engine failed to start"]

I had recently posted that the engine Wise Anti Malware " engine failed to start:. I uninstalled the program and downloaded it again and saved it to my desktop and reinstalled it, This time I paid closely to the instructions and waited for the "engine with its definitions to install completely  then I ran the program and did a full scan, it worked smoothly! I might add that although this program is compatible with "windows defender", you might want to disable any other malware protection while installing it. WISE PATIENCE is the KEY! 

["Engine failed to start"]

I downloaded the new product  "wise Anti-malware" on two of our computers and I cannot scan from either one, they both come up with "engine failed to start". Must I download them again to get a new engine?
