Hi @BlackEagle,

I've encountered similar issues twice before where an upgrade appears successful, but the Windows service disappeared post-upgrade. It's been quite a few years since I've seen it happen and may be patched, but I'll share my personal experience and the resolution we found.

We discovered that affected machines had a newer version of Microsoft C++ Redistributable than what the installer expected, so the installer skipped installation, which somehow affected the ArcGIS Enterprise Windows services.

What to check:

According to ArcGIS Enterprise 11.5 system requirements, the minimum required is C++ 2015–2022 Redistributable (x64) version 14.38.33130. Check if your machine(s) have a newer version than that installed.
On the affected machine(s), use file explorer to look in %appdata%\..\local\temp for C++ redistributable installation logs. You may find logs here that tell you C++ redistributable was not installed.

Resolution:

Uninstalled C++ Redistributable on affected server machine(s)
Run a repair on the respective Enterprise software component installation
Windows services reappeared after the repair

Some other things to consider:

Anti-virus / malware protection agents
Ensure user that installs/upgrades has sufficient permissions to all directories
