When you try to open an Office file that is blocked by your Registry policy settings, you may get the following error message You are attempting to save a file that is blocked by your Registry policy setting. The error message could be also be worded as follows:
- You are attempting to open a file that was created in an earlier version of Microsoft Office. This file type is blocked from opening in this version by your registry policy setting
- You are attempting to open a file type File_Type that has been blocked by your File Block settings in the Trust Center.
The issue is mainly noticed when a user tries to open an embedded or linked Office file in an Office application. A simple change in settings can fix the problem. Let's see how!
You are attempting to save a file that is blocked by your Registry policy setting
To fix this issue, try changing the File Block settings to disable the restriction imposed on certain file types as follows:
- Open Office application and go to Options window
- Access Trust Center Settings
- Clear Open and Save boxes for File Block Settings.
1] Open Office application and go to Options window
Open any office application like Microsoft Office Word, PowerPoint or Excel and go to the 'File' tab.
Click it and select 'Options' from the sidebar.
2] Access Trust Center Settings
Now, when the 'Options' window opens, select 'Trust Center' from the left pane and hit the 'Trust Center Settings' button visible in the right pane. This section contains Privacy and Security settings that keep your computer secure. As such, it is recommended to not change these settings. However, if you do not mind tweaking it, proceed further.
3] Clear Open and Save boxes for File Block Settings
Here, in Trust Center window, select 'File Block Settings', and then clear the 'Open' or 'Save' check box for the file type that you want to open or save. Clearing the boxes enables a user to allow the user to open or save the file. Checking the same blocks access to the file/s.
When done, hit the 'OK' button visible in the lower right corner of the Trust Center window and try opening or saving the file that was blocked earlier.
The problem should have been resolved by now. So, now when you try and open an Office file you should no more see 'You are attempting to save a file that is blocked by your registry policy setting' error message in Windows 10.
