Files open as read-only

We’re currently investigating this issue. Some users report that trying a second time and the file will open without the message so you might just be able to persevere to get it working.

Another possible culprit is the Preview Pane in Windows Explorer. Try disabling that and see if the error continues.

Finally, as @thomthom mentioned, this may be tied to the thumbnails and the workaround to rename the “thumbsup.dll” file to “thumbsup.old” may work as well.

Be sure to let us know in this thread which, if any, of these suggestions help.
