I purchased my copy of PC Matic yesterday. After several failed attempts to install the application, I contacted the customer service, but they didn't help me and I'm still unable to install the tool. I followed all the instructions, including uninstalling Vipre using Revo Uninstaller and I'm still getting this error message:

File: PCMaticUI.js?15973
Line: 2710
Error: Unable to get property 'SetString' of undefined or null reference.

I'm so discouraged!

According to PC Matic's official forum, there could be a number of causes for your problem:

  • Your firewall may be blocking the application, so you should check to see if that's true or not.
  • If you're using a wireless connection you may need to switch to a wired one.
  • You need to use Internet Explorer as the application requires the ActiveX software framerwork.
  • Lastly, try using application in Windows Safe Mode with Networking. In case it works like that, but not in the regular Windows Mode, it's clearly a firewall problem.

As far as the text of the error goes, in my experience that problem generally appears when developers forget to check if a specific field in the JavaScript code is empty before continuing to the next step.
