Runtime error 6 Overflow

Over time we have found a few issues that can trigger this error message.

Screen/Window Size Issues

On screens that are significantly wider than they are tall, we have seen cases where the Toolkit program window has been opened wider than it was designed for. When you first open Toolkit, you will notice a blue background, which seems to never end. If the Toolkit window is opened wide enough however, you will find the blue background eventually stops and is replaced by a gray or black area, which will usually show up on the far right-hand side of the window. If that happens to you, the first thing will be to try re-sizing the Toolkit window.

If the Toolkit window is Maximized, or set to take up the entire screen, start by clicking the Restore button near the top right-hand corner of the Toolkit window. The Restore button is just to the left of the large X button in the very top right-hand corner of any regular windows program. Clicking the Restore button will shrink the Toolkit window down a bit, to where the error should no longer occur.


A GIF showing a Windows being resizedIf you find that clicking the Restore button makes the window too small, it can always be re-sized manually. Place the mouse pointer over the edge of the window on any side, and you will see it change from a pointer to a double-sided arrow. Click and hold down on the regular left-hand mouse button, then move the mouse to adjust the size of the window.  The image here  shows an example of what resizing a regular window can look like. Keep in mind that if you start on the right or left hand sides, the window will only get bigger or smaller in those directions; if you want it to be taller, make sure to start at the top or bottom of the window instead. The image used in this example is from: , a handy site where you can learn other useful information like this.

Another method, if you want to make a large change in the window size: Hold Down the Windows key on your keyboard, and tap the left or right arrow key on your keyboard. Starting with Windows 7, this has the effect of snapping the window to the left or right-hand side of the computer screen. From there, you can always use the previous method, to make smaller changes.

A third option is:

  • Make sure the Window you want to re-size is selected.
  • Press Alt + Spacebar to open the window menu.
  • If the window is maximized, arrow down to Restore and press Enter, then press Alt + Spacebar again to open the window menu.
  • Arrow down to Size, and press Enter/Return on the keyboard.
  • Press the up or down arrow key if you want to resize the window vertically or the left or right arrow key if you want to resize horizontally.
  • Whichever key you press first is where the re-size arrow will jump to. In the image above for example, we needed to get the right-hand side of the window to move closer to the left. Press the right-hand arrow key first, so Windows knows which side you want to work on. Then, press the left-hand arrow key, to re-size the window in that direction.
  • Once you have the window re-sized, press the Enter/Return key on your keyboard to stop resizing.

Other Possible Causes

We have also seen some cases where working with a particular stock either in a portfolio, or in a report, can cause the error to appear.
This will usually happen with companies who have less than five years of history filled in; several reports make use of five year averages when displaying information, so if the company is too new, it may trigger an error. To date, this has been most often seen and confirmed in the Stock Comparison report. If you have recently added a company with less than five years of history to the library or to a portfolio, and are now seeing the error 6, we suggest to try deleting that company from the library or portfolio, to test if it is causing the error.

We have also seen cases where this error seems to occur if Windows is not fully up to date.

The next time you get that error, please try the following steps:

1. Click OK, and let Toolkit close.
2. Re-start the computer.
3. When the computer comes back up, go down into the Start menu > All Programs, and select Windows Update.
4. Go through the Windows update, and have it install any available updates.
5. Once you have all the updates taken care of, have the computer re-start again.
6. Repeat steps 3, 4, and 5 at least once, to make sure that there are no more available updates.
From here, we suggest to make a backup of your Toolkit data, and then re-install the program, as follows:

Open Toolkit and click on Options > Database Utilities.
Select the first option, to make a backup of your database
Select C:: -Fixed from the drop-down menu, and click OK.
From the list of places, go to the top of the list, and choose Desktop.
Click OK
Toolkit should report that the database was backed up. Click OK

Uninstalling Toolkit

First, close any open windows. Then:

Follow the on-screen instructions, including any accepting requests to remove files. You can save time by using the check-box that says to use the same choice for all options, and then clicking YES.
Once the program is removed, reboot your computer.

Click on DOWNLOAD next to the TOOLKIT 6 icon, and then Download again on the following page.

Restoring your backed-up data

If you skipped the section on Backing up your data, you can skip the steps for Restoring your data as well.
Open Toolkit and click on Options > Database Utilities.
Select the second option, to restore a backup of your database

On the window that opens, choose Desktop on the left hand side of the window.

If these steps do not resolve the error, there may be a further issue that we have to date not yet identified since this error first appeared.

In that case, there are several options:

-While unusual, we have had a small number of cases where this error has stopped occurring. To date, the only common thread for the cases where this has happened is that some software other than Toolkit6 was updated on the computer. As such, we do encourage you to make sure all of the software on your computer is up to date.

-If you have a separate computer, we encourage you to install Toolkit there

-Since we do not currently have a specific patch or update to address this issue, we do also understand if you would rather not keep the software. In that case, please let us know, and we can work on either getting a refund for the purchase, or finding an alternative, such as one of the online ssg preparation tools.
