Error opening file: File is locked by another. Would you like to open a read-only copy of this file?
If you are receiving this message when attempting to open a PDF file, this is most likely caused by the Preview pane in Windows. Windows does not have a native PDF viewer to display PDF files in the Preview pane, so Windows will use Acrobat to display the files. The Acrobat preview marks the file as "in use" when displaying the preview, which causes Revu to display this message when attempting to open the file.
There are different options for working around this message. In Revu 9.5 a Bluebeam "previewer" for Windows Explorer was introduced that will not mark files in use. Revu 9 users running version 9.0 to 9.2.1 can install this free update and set Bluebeam as their default PDF viewer to prevent this message from appearing. You can download Bluebeam PDF Revu 9.5.1 from www.bluebeam.com/updates. Users already running Revu 9.5 or higher can set Bluebeam as their default PDF viewer to prevent this message from appearing.
The default PDF viewer can be changed using the Bluebeam Administrator application:
- Open Revu.
- Click Help > Administrator.
- Click the Revu tab in the Administrator.
- Check the Use as default PDF viewer check box and click OK to set Revu as the default PDF viewer.
There is also a way to turn off this message from the Revu Preferences. Depending on your version of Revu:
Click Edit > Preferences
- or -
click Settings > Preferences
- or -
- Click Document on the left.
- Clear checkbox for Prompt user if file is locked.
- Click OK to save the setting and close Preferences.
Note that if a file is still marked in use by the Adobe previewer, you will not be able to Save the file, and will receive an error stating "The document could not be published. The process cannot access the file because it is in use by another process." Select a different file in Windows Explorer to preview and then save your document.
If the file is stored on a network and you are receiving these errors, be aware that another user may actually have the document open. Additionally, some network processes like backup or synchronization utilities may also mark files as "in use" which can result in these errors when attempting to open or save a file.
