Question

How can I start CADRaster while AutoCAD is already working?

Answer

It is possible in R14 and R13 only. To start CADRaster call AppLoad command from AutoCAD command prompt. On dialog, which appear, select from list proper arx file or add it to the list using File... button.
For AutoCAD R13 you have to use cdrsrv13.arx, for AutoCAD R14 - cadr14.arx. This procedure you can use with either PRO and LTX versions.
Known limitations and problems:
AutoCAD's message:
Loading c:\CADRaster PRO\Cadr14.arx ...
c:\CADRaster PRO\Cadr14.arx cannot find a dll or other file that it needs.
File c:\CADRaster PRO\Cadr14.arx is invalid.
Problem description:
This problem appears when a valid DLL can not be loaded. There can be two reasons:
  • Reason 1.
    First is the registry path:
    'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
    \CurrentVersion\AppPaths\acad.exe'
    was wrongly updated or doesn't exist. Every new installation of CADRaster should add its path on the end of that registry entry. If there is more then one CADRaster path (the rest of previous installations) you must erase all old paths, because DLLs are searched in every directory specified in that string in order of appearance. If you have anywhere an old CADRaster's DLL and path to its directory precede the newest path, message described above appears.
    Solution:
    If registry variable doesn't exist do not try to add it, simply look for other possibilities, how to solve this problem, described bellow. If registry variable includes an old path to CADRaster's dll erase this path from there. (Be sure that this path is not used by other users).
  • Reason 2.
    Second possibility is that system variable 'path' include any path to directory with an old CADRaster's dll. Also here is important the order of paths appearance.
    Solution:
    If system variable includes an old path to CADRaster's dll erase this path from there.(Be sure that this path isn't used by other users).
More Info:
If you want to keep few AutoCADs working with different CADRasters methods described above will be not sufficient. In this case you must erase all CADRaster's paths from registry variable:
'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\AppPaths\acad.exe'
and from system variable. Then for every AutoCAD you must set valid working directory. Its mean directory to proper CADRaster. You can do this simply changing one of AutoCAD's shortcut properties named 'Start in'.
AutoCAD R13:
If you want to call CADRaster after AutoCAD running, AutoCAD must be configured to work with CADRaster Display Driver. In this case CADRaster is loaded by every AutoCAD running and displays its menu. When AutoCAD R13 works with other display driver arx loading invokes an error message.
