System.ArgumentException Parameter is not valid

System.ArgumentException Parameter is not valid

PROBLEM

  • In Gorilla when going to open either the Document Manager, Message Queue, Scratchpad, or other new forms within Gorilla the user would get the error:

System.ArgumentException: Parameter is not valid. at System.Drawing.Font.GetHeight(Graphics graphics) at System.Drawing.Font.get_SizeInPoints() at System.Drawing.SystemFonts.FontInPoints(Font font) at System.Drawing.SystemFonts.get_MenuFont() at System.Windows.Forms.ToolStripManager.get_DefaultFont() at System.Windows.Forms.ToolStripItem.get_Font() at System.Windows.Forms.ToolStripItemInternalLayout.CommonLayoutOptions() at System.Windows.Forms.ToolStripDropDownButton.ToolStripDropDownButtonInternalLayout.CommonLayoutOptions() at System.Windows.Forms.ToolStripItemInternalLayout.GetLayoutData() at System.Windows.Forms.ToolStripItemInternalLayout.PerformLayout() at System.Windows.Forms.ToolStripItem.OnBoundsChanged() at System.Windows.Forms.ToolStripDropDownItem.OnBoundsChanged() at System.Windows.Forms.ToolStripItem.SetBounds(Rectangle bounds) 

CAUSE

In this case the error was being caused by the font "Tahoma (True Type)" not properly being referenced within the Windows registry. 

SOLUTION

Because the solution involves changing items within your registry, you will need to call Software Support at 801-553-9888 so that we can remote in to apply the solution. 
If Software Support is not able to remote in, we will walk you or your IT through the process.
