Unfortunately, I'm getting this also - minus the Alert shown in previous post. Tried uninstalling/ reinstalling but to no avail. The Windows Installer does say "an uninstall module failed to install properly" (paraphrasing). There was a recent Windows 10 update and an X-Plane 11 update as well (11.10b2) I think.
Usually I don't post in the forums as I rely on submitting a ticket but wanted to let you know, you're not alone. I'm sure there will be a fix eventually.
[EDIT] Resolved here:
Lesson I Learned: Read all of the related forums. Thanks Ben, Sorry Cameron.
