PCs are currently equipped by the operating systems Windows 7 or Windows 8, mostly in 64bit-version.
The computers have got no RS232-connection and notebooks cannot even be equipped with this connection later.
The following text tells you how to instal and use nccad under these conditions, examples concern nccad7.6 and Windows7, but are valid for nccad7.5 and Windows 8, too.

Among others - nccad9 was created to match modern operating systems. It works fine with Windows 7 and Windows 8. But it may cause problems under Windows 10 - depending on the downloaded version of Windows 10. According to current information these problems are not clear.
At present we must advise against the installation of nccad9 under Windows 10!!

Run-time error 13
The "regional options" (menu in der control panel of your PC) must be adapted:
"Start" => Settings => Control panel => Regional options
Change the region in the tab "General" to "German"; save it by "OK".
Or change the decimal separator from point to period, or vice versa.
This should help in most cases.

This message is very rare and suggests different causes which, as a rule, have to do with your operating system. A disc clean-up tool helps in most cases.

"File could not be opened"
Has the file the right format? Please check the format and convert it in a compatible one, if required.
The file is possibly damaged and must be newly generated.
Another cause may be that the drawing was made in a very new version of "nccad" and the machine has installed an older software. As nccad is not backward compatible, think about buying an update which will pay off soon!
