Phar Lap err 58

[aliam]

Hi dear

I try to run ACADR12 old Autocad version on vDos in Widows 11 x64, setting exactly same AUTOEXEC.BAT on DOS6.22 but when run batch file of this program see this message : Phar Lap err 58: Can't create VM swap file of size 400000 in directory C:\

how to resolve this problem?

thanks

Since ACADR12 is a graphical program, you'll probably be better off with DOSBox. vDos only supports basic VGA, so you will be limited to a 640x480 resolution.

No real idea why ACADR12 needs a swap file as it operates in virtual memory mode. You would have no write permissions for vDos C:.
You could have a look at jeffpar.github.io/kbarchive/kb/099/Q99575/, or google for the error message.
