Convert the negative decimal number to a hexadecimal number and you get a more common error number.
For example -532462766 does not give many hits so you don't know what kind of exception it is.
Open Windows calculator and set it to the programmers view.
Select decimal (DEC) and paste the value.
Now switch to hexadecimal (HEX) and you will get: FFFF FFFF E043 4352
Now if you remove the 8 F's in front you get the hexadecimal exception code E0434352
When you now search for error code E0434352 it looks like a generic .Net unhandled exception.
