Run-Time Errors nccad7*

Date: February 2018

Run-time error 13
"type mismatch"

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.

Run-time error xxx
"out of memory"

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.

Run-time error "xxx":   
"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!
