Microsoft project management software used to plan, manage, and communicate a project schedule and other information among workgroup members, project managers, and other stakeholders.
Thank you for the details information
Here are a few steps you can try next:
- Save the file as XML
- Open the problematic .mpp file. Go to File > Save As. Choose a location and change the "Save as type" dropdown to XML Format (*.xml). Save it.
-
-
- Completely close the current project file.
- Open MS Project with a blank screen. Go to File > Open and browse to the .xml file you just created (you may need to change the file type filter in the open dialog to see XML files).
- When the Import Wizard appears, choose "As a new project".
-
- Check the Gantt chart area to see if the screenshot is entirely gone. If the file is clean, go to File > Save As and save it back as a standard Project (*.mpp) file.
Note: You may lose some highly customized visual formatting (like specific bar colors you changed manually outside of the default styles), but the structural data will be intact.
2. Overwriting the Corrupted View via Organizer
If the corruption is isolated specifically to the Gantt Chart view rather than the whole file, you can replace the corrupted view with a clean, default version from your global template (Global.mpt).
- Open your problematic project file.
- Navigate to File > Info > Organizer (or View > Macros > Organizer depending on your exact version).
-
- Select the Views tab.
- On the left side (which should display Global.mpt), locate Gantt Chart.
-
-
- On the right side (which should display your current project file), you will also see Gantt Chart.
- Select Gantt Chart on the left side (Global.mpt) and click the Copy >> button in the middle to push it to the right side (your project).
- Project will warn you that the view already exists and ask if you want to overwrite it. Click Yes.
-
- Close the Organizer, save your file, and restart Project to see if the screenshot has been deleted.
