Hi Everyone,

I've recently started my own business selling engineering-orientated software. So far I've only made one application, which is an Excel-based spreadsheet for determining the performance of rainwater harvesting systems.

The problem I am having is that I am based in the UK and I've had a few emails from people in the US who have tried to download the demo Excel file, which is basically the application but with most of the features disabled, and they say it doesn't work. E.g. they get errors when they try to open it, or it opens but the text and objects within the app. are garbled.

It works on every machine that I've tried in the UK (mine and some friends of mine) so I was thinking can it have anything to do with Window's region settings? I can't think of anything that should be different - Windows and Excel are supposed to be the same everywhere, after all.

Can anyone think why my app seems to work fine in the UK but not in the US?

If anyone from outside the UK wants to have a look at it for me, here's the link:

It has macros in it - I promise they are safe! They won't damage your PC or anything stupid like that. Or you could disable them and just see if the front-end looks okay - it should be a flow-chart if it's working properly, but the reports I've been getting have said that the flow-chart objects are messed up, so obviously something's not right somewhere.

Cheers
