Hi all,

I was trying to upgrade from Ignition 8.1.9 to 8.1.20. However, I have been seeing “unable to alter ownership” message whenever I run the installer.

I am running the upgrade as an Admin and I checked that I have all the required permissions.

Any ideas on how to solve this?

Can you look for the `install.log` file?  
It should either be in the install directory or in your user profile directory:

> If you continued it will be in the install directory as install.log, otherwise in your user folder under `.ignition/install/install.log`

Is it this one?

Yes, that’s it.  
It looks like it might be an issue with filename/filesystem encoding:  
`java.nio.file.NoSuchFileException: C:\Program Files\Inductive Automation\Ignition\data\projects\.resources\33ae33c645ac06ff52a3042쒯䬑ǘハ彬䬑ǘハ彬䬑ǘ秥䴖塅ǘ`

I’ll get this in front of the relevant people on the team to see if there might be some workaround.
