Frequently asked questions


Question  Answer 

Can I download the calculators?

No. To ensure calculations are made using the current rates and thresholds, calculators cannot be downloaded.

I only get a blank screen when I try to use the calculators. Is there a problem with my system?

If you are using Internet Explorer and have AVG anti-virus installed on your computer, the AVG add-ons may be affecting the way Adobe Reader works.

To remove these add-ons:

  1. Open Internet Explorer
  2. Go to Tools > Internet options > Programs 
  3. Click on Manage add-ons 
  4. Untick AVG SafeSearch, AVG Security Toolbar and AVG Security Toolbar BHO 
  5. Close Internet Explorer

If this doesn't work, right-click on the AVG User Interface, double-click on the LinkScanner and untick Enable AVG Search-Shield and Enable Active Surf-Shield.

Remember to re-enable the add-ons when you have finished using OSRconnect. You should contact your IT or system administrator for advice if you intend to leave the anti-virus
add-on permanently disabled.

Why do I get the error response 'the browser is not supported' when I try to use the calculators? Is there a problem with my system?

If you are using Windows 8, it is currently not supported by our calculators.

However, OSRconnect will automatically calculate your liability once you click Save.
