On my last order I purchased a Standox Standowin Formulation CD only to find out that it is not compatible with Windows 10 which I discovered when I attempted to download it on my main computer and after repeated failures it failed on any of my 3 computers. These have all been upgraded to Windows 10. On each attempted download the software froze. I did query the problem with your office and was informed after several calls that the software providor was not issuing a Windows 10 compatible disc???? If this is the case then you should advise on your publicity material. I also find this a somewhat strange directive as in many cases Windows 10 has been automatically uploaded by Microsoft and support for Windows 7/8 is being suspended. I was told that in order to obtain colour formulations I would have to obtain them online via Standox. This is fine if you have a good wifi signal when working from a van!!!. My saving was that I managed to download the new disc on to an old laptop with the Windows XP operating system. I would welcome your comments on my feedback.
