Having trouble installing your LabelWriter?

It has been discovered that some LabelWriter printers manufactured after April 1, 2014 will not properly install on Windows 7 PCs when attached to a USB 3.0 port. DYMO has developed an update that will fix this problem on these printers.

If you are having installation problems with your Labelwriter and think it could be affected by this problem, then check your serial number against the numbers below.   First, identify your product and region.  Then if the serial number on your product is GREATER THAN the number listed you have an affected product (and if it isn't, you don't):
