Priority: medium
Bug ID: 77057
Assignee: [email protected]
Summary: Installing/uninstalling LibreOffice messes up the
KindMap in Windows 8.1
Severity: major
Classification: Unclassified
OS: Windows (All)
Reporter: [email protected]
Hardware: x86 (IA32)
Status: UNCONFIRMED
Version: 4.2.2.1 release
Component: Installation
Product: LibreOffice
On the Microsoft forums, a number of users reported that the Photos app in
Windows 8.1 no longer worked. It would show folders of photos, but it wouldn't
display the actual photos - it would just say that the folders were empty.
This turned out to be related to this registry key: -
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\KindMap
Listed under that key are file extensions. Affected users noted that the keys
for all image file extensions had been changed from "picture" to "document",
which is what caused the bug in the Photos app. Manually changing the value of
each affected key back to "picture" and then rebuilding the search index fixes
the issue.
This issue affected 2 of my machines, so I posted a list of the software that's
installed on both, which includes LibreOffice. Another user also reported that
he had LibreOffice installed, so that started to look like the likely culprit.
So, I then uninstalled LibreOffice entirely. On doing so, ALL photo file
extensions were removed from the KindMap altogether. I then reinstalled the
latest version of LibreOffice and all of the photo extensions were added back
into the KindMap, but they were all set to "document", which again breaks the
Photos app.
It appears that the bug has 2 elements then: -
1. Installing LibreOffice changes the registry keys for image file extensions
in the KindMap from "picture" to "document", breaking functionality in Windows
8.1 including Microsoft's standard Photos app.
2. Uninstalling LibreOffice remove the registry keys for image file extensions
completely from the KindMap, which causes the Photos app in Windows 8.1 to fail
to display thumbnails (and it may have other unwanted effects).
Thanks.
