Microsoft Office users may find that some of their applications are failing to open when called on by third-party applications. It’s an issue that has emerged after the latest round of Microsoft updates.

The problem affects Word, Excel, and other Office applications opened from third-party offerings including CCH Engagement, Workpaper Manager, Zotero, or dental office software such as Dentrix or Softdent.

The update issued on June 9 appears to have triggered problems with the OLE automation that these third-party applications use to interact with Office. Users have reported that files are failing to open, with no error message indicating what has gone wrong,

According to one Windows user forum, the issue is particularly frustrating because of this lack of error message. As one user put it, “‘Word won’t open from our workpaper system’ is functionally the same as ‘Word is broken.’ To an administrator, the difference determines whether the next hour is spent repairing Office, rolling back Windows, calling a line-of-business vendor, or opening a Microsoft support case.”

Microsoft has said that it is aware of the issue and is working towards a resolution.

Deleting mystery file

The company is also looking to fix a minor issue that has emerged from this latest round of updates: Users are finding that when items are deleted, the confirmation dialog box displays the internal Recycle Bin file name (for example, $Rxxxxx.ext) instead of the original file name. However, Microsoft stressed that in the Recycle Bin, the item still appears with its original name.
