Below is a list of errors that rarely occur. Click on the the error to find a fix.

For problems related to the installation, see Install Problems and Fixes.

For problems related to printing, see Printer Problems.

Arithmetic Overflow Error

An arithmetic overflow error can occur if an older version of ROBOTILL is used. Upgrade to the latest version of ROBOTILL to prevent the error from occurring. The upgrade will prevent the error from recurring. To fix the error follow the steps below. 

If you get the error when you access the product list in ROBOTILL Back Office:

  1. In ROBOTILl Back Office, go to Home > Products and Stock > Stock Level Management > Stock Take List
  2. Go down the list and find the item(s) with an incorrect stock on hand value. The problem item(s) will be obvious as it will have a huge stock on hand amount (too big to be a actual stock on hand). Enter the correct stock on hand for the item(s).
  3. You can also check under 'show compound items' for incorrect stock on hand values.
  4. The problem will be fixed once you corrected the values.

If you get the error in ROBOTILL Retail/Restaurant, either when logging in or when you want to add items to a sale:

  1. In ROBOTILL Retail log into the retail app with the user that is giving the error, or in ROBOTILL Restaurant select the table that is giving the error.
  2. Void the sale (even if you don't see any items in the sale).
  3. The problem will now be fixed.

SQL Server Timeout Error

If you get a SQL Server execution timeout error, it means that your server is running low on resources and is unable to complete the command on a timely basis. Close all other programs that are open (including browsers, email, music, etc) and try again. If the problem persists, you will need to upgrade your computer hardware. 

Invalid class error / Invocation of constructor error

If you get an 'Invalid Class' error, or an error about the 'invocation of the constructor' (the error message will be longer) it means that there is a corrupted file on your computer that ROBOTILL needs. Follow the steps below, do not skip a step and proceed to the next step only if the problem persists.

  1. Uninstall ROBOTILL and install again making sure you install the latest version - follow these instructions.
  2. Restart your computer. If you still get the error, continue with the steps below.
  3. Run all outstanding Windows updates. Do not skip this step as new Windows updates sometimes install newer .NET frameworks - it might replace the corrupted file.
  4. If the above did not work, then you will need to reinstall Windows. It is easy to reinstall Windows from Windows 10, but once that is done you will need to reinstall all the programs that you use. To reinstall Windows go to your Windows Settings > Update and Security > Recovery. Please note installing Windows does not fall under ROBOTILL Support. If you have any problems you will need to contact your local IT support company.
