Sorry again as this is very frustrating to say the least. I would resubmit that support ticket and tell them that this issue is not resolved. They can remote into your computer and fix this.
I am not sure if this will work but did you say you went to the Google Play Store? Can you try to see if the PWM will install from here to your mac? https://chrome.google.com/webstore/detail/webroot-password-manager/ngkhgikojglcgnckopipfdajaifmmnnc
The only other thing I could suggest is a uninstall/reinstall of webroot.
Otherwise you couuld get a hold of Support by calling them here: You may be on hold for abit but they will gladly help you.
