Problem:
Receive an LP360 COM Exception attempting to open files for read/write.
Caller’s Message:
Failed to open the file for read/write. The file ‘D:\Client_Data\sample.las’ cannot be edited. (18309)
Exception Information:
HRESULT: 0x0
Unable to retrieve extended COM error information.
Probable Resolution:
- Verify that the files are not open for read in another session or program.
- Close ArcMap, reopen and try again. Sometimes Arc holds onto a file that has been removed or closed by the user until that session is completely closed.
- Verify when you close ArcMap that the ArcMap process actually closes and you don’t end up with a process showing in Task Manager despite there being no associated GUI.
