Andrey,
I don’t know what to say; I don’t think I have found anything useful.
As shown below, I tried running from the console “Tonfotos-1.11.5 Setup.exe”, then “setup.exe,” then “setup,”:
C:\Users\pfryo\Downloads>Tonfotos-1.11.5 Setup.exe
'Tonfotos-1.11.5' is not recognized as an internal or external command,
operable program or batch file.
C:\Users\pfryo\Downloads>setup.exe
'setup.exe' is not recognized as an internal or external command,
operable program or batch file.
C:\Users\pfryo\Downloads>setup
'setup' is not recognized as an internal or external command,
operable program or batch file.
This is the only SquirrelSetup.log file on my computer created recently. It was created on Monday when I first started trying to install Tonfotos. I don’t have a more current version even though I have tried repeatedly to install Tonfotos several different ways. It is the log I already sent to you.
C:\Users\pfryo\Documents\Tonfotos 3/10/2025 9:32 AM
SquirrelSetup.log 3/10/2025 9:32 AM
SquirrelSetup.log is a shortcut pointing to:
C:\Users\pfryo\AppData\Local\SquirrelTemp\SquirrelSetup.log 11/29/2024 11:38 AM
It was created a few days ago and modified a few minutes ago as shown.

That may explain why the third line: “About to install to: C:\Users\pfryo\AppData\Local\Discord,” doesn’t make any sense.
So it appears that running the install doesn’t even create a new log file in this case, it just modifies the existing shortcut pointing to an earlier installation.
Something was working earlier today that is not working now (by comparing the folder at two times).
C:\Users\pfryo\AppData\Local\SquirrelTemp 3/12/2025 11:29 AM

I don’t think I found anything useful. If you have more suggestions, I will certainly try them.
