Dynamic link library gdiplus.dll could not be found

RentalDesk NX uses components that need a particular Windows file to be installed. Most Windows machines have this file, but occasionally it may be missing

You can download the Windows update you need from HERE     

Note: The Microsoft download file is less than helpful...it just self extracts to a folder of your choice and then when you go there lots of subfolders are to be found. So if you delve down into ..asms\10\msft\windows\gdiplus you should find 3 files, including gdiplus.dll. Copy these to your Windows SYSTEM32 folder, e.g. c:\WinNT\System32 folder, or c:\Windows\System32
