Usually "unable to obtain a lock" means that the previous instance of GnuCash crashed or was force-stopped. But you say that didn't happen, and if it had then you would not get the "unable to create a backup" error when trying to save the file.
That error suggests that for some reason you do not have the ability to write to the directory (in Windows, "folder") where your main GnuCash data file lives. It could be a permissions problem, or it could be that the disk is full -- anything that prevents files from being written. If my analysis is right, you get "unable to obtain the lock" because GnuCash is unable to create the .lck file -- again pointing to permissions problem in that directory or folder. -- Regards, Stan Brown Tompkins County, New York, USA https://BrownMath.com http://OakRoadSystems.com On 2019-09-25 12:48, Sadhna True wrote: > When I open GnuCash, I get the error message "unable to obtain a lock."
