RC Layer Limits Viewer version 18.104.22.1681019 updated this afternoon, after I published my viewer updates. :/
My viewer attempted to update to this version. I had an in viewer notice that a new version had downloaded. I clicked to have it go ahead and install. That was a mistake. It could not install and I started getting a series of install problems. I finally canceled out of the install and restarted the viewer.
On restart I got a notice that a problem with the update had occurred and was given a link and instructions to download the viewer and install the download. The manual download and install worked without a problem. The viewer launched and logged in without a problem.
