Can't run 1.8.3, can't upgrade to 1.8.4

[Asael]

1.8.3 does not start (nothing happens).

Tried to "repair", got setup failed message.

Tried to upgrade to 1.8.4, got "the older version of Affinity Publisher can not be removed"

Tried to manually uninstall 1.8.3, get "The feature you are trying to use is on a network resource that is not available" ... or enter alternative path to the folder containing the installation package "Affinity.msi". Use source: C:\Users\...\AppData\Local\Temp\AffinitySetup\d8d0b681-cade-11ea-835d-74d02b989015\

Suggestions?

If you’re getting an error Setup Failed when trying to install our app/update, please try the below suggestions. They should hopefully allow you to install our app/update without any further issues:

• Restart your machine and try the installation again
• Make sure you're installing the latest version of the app ( more information here )
• Right click the .exe file and select Run as Administrator
• Make sure your machine isn't in the middle of installing updates - this can lock files needed to install our app/update
• Make sure your machine is fully updated by checking for any available updates
• Uninstall any previous versions of the software first using Microsoft's Uninstall Troubleshooter app (some errors have been caused by the installer being unable to remove the previous version)
• If you’re using an app, such as ImDisk, to modify where your TEMP directory is stored, please disable this and use the default Windows TEMP directory.
• Make sure you have the correct permissions to add/modify or remove folders within C:\Program Files\
• Check Event Viewer to see if any additional information is provided regarding the error ( more information here )

MS Uninstall Troubleshooter eventually did the trick, thank you!
