>”The exe should be called Fileside.exe. Where do you see this weird dealseeker thing?”
“Weird” is correct. I save a copy of the Start Menu shortcut with the downloaded file. For some unknown reason, I have a program named Dealseeker installed. Its Start Menu icon (in Explorer, Type sorted mode) was next to where the Fileside icon would be installed, but it had not shown up yet. When I copied the icon to place with the downloaded file, I was copying dealseeker thinking that was its executable name.
I never intentionally installed dealseeker myself. Some other program must have thought I would appreciate them sneaking it in without telling me. Now, I will have to figure out what I installed on the same date as dealseeker (November 4, 2022).
In conclusion, no, you did not name the Fileside executable with some weird name after all. I also checked and fileside.exe is working fine nearby.
