OK, I found that if I delete the `IgnitionGateway.exe` file from `C:\Program Files\Inductive Automation\Ignition` folder, then the 8.1.28 installation goes through OK and the gateway will start normally. But then, if I start the 8.1.28 installation AGAIN and upgrade, the gateway will NOT start. And if I delete the `IgnitionGateway.exe` again and start the 8.1.28 install, the gateway will start... 😕 ---

Could you upload your install.log and install-info.txt files from after the upgrade? The log file should be in the `logs` folder and install-info.txt is in the `lib` folder. ---

I’ll have to look into it more on Monday, but it seems like it may be failing due to the backslash in the username. Is the username showing as the same on 8.1.27? ---

I was able to replicate this, and it's the `\u` that's tripping it up. This will also happen on 8.1.27, so I'm curious as to why `DESKTOP-8T2EMTA\` was added to the username. From what I see, it gets added when using a specific user account to run the Ignition service. Between the installation of 8.1.27 and the upgrade to 8.1.28 did you change the account the Ignition service is running as? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/4/0/40a52bc63f98a444ed5e8c593bc9af8a5ed760f6.png) ---

No. Service is always running as System (default). I tried with various upgrades, from 8.1.21, 8.1.23, 8.1.26 and 8.1.27 to 8.1.28 and it's always the same: Prior to upgrade, the username is without PC name and backslash, after the upgrade to 8.1.28, PC name and backslash are added... ---

I filed an internal ticket to get this addressed, but it looks like the optimal solution is to escape the `\u` with a second backslash. ---

I'll be completely honest, I've never even noticed that option before and don't know anything about it. Checking it though did seem to cause the username to update during install/upgrade to include the user origin and backslash. Edit: I see from [this](https://forum.inductiveautomation.com/t/interacting-with-desktop/44443) thread that it's mentioned after Windows 7 it isn't really usable. ---

Not sure why `DESKTOP-8T2EMTA\` is getting added in the first place then. I did do some testing and noticed that once it started to get added during upgrades, I had to restart my entire system to get it to stop. Ultimately, for now the best thing to do is to manually set the username so it doesn't include the `\u` or escape it with an extra `\`. Or change the user name to not start with `u`. Then once the fix is in place in a future update, you won't have to worry about it. [Next page](https://forum.inductiveautomation.com/t/bug-7829-ignition-upgrade-to-8-1-28-failed/74527.md?page=2)
