When I opened SA (v4.0.0.51819) this morning, a message appeared to tell me an update was available. I went through the process to update SA to v4.0.1.54588. After a few minutes, this message appears: "We ran into a problem. Restart your PC, then try again." Error code: 1603 appears in the bottom right of window. According to the web page that opens when I click on the error code, a fatal error occurred during installation. The possible recovery options state to restart my computer and try to install again. When I did this, the update failed again (surprise!) with the same error code 1603. I've tried this several times, all with the same result.

I should also note that since I installed SA v4.0.0.51819, I have not been able to sign in to SA with my Dell.com credentials. This has been widely reported in previous posts. Fortunately, I am still able to run the various SA tasks.
