His log reaches 'entering wails.Run' and stops: WebView2 is installed
(120.0.2210.91) and never hands control back. A hang, not a failure —
there is no error to report, so the two remaining causes have to be
addressed rather than diagnosed.
The profile folder is now named explicitly, on the LOCAL disk. Wails
defaults it into the ROAMING profile, which on a managed account can be
redirected to a share; a WebView2 profile on a share that is slow or gone
does not fail, it hangs. Naming it also gives someone a folder they can
be told to delete, which is the fix when the profile itself is corrupt.
And a marker is written before the window is attempted, removed when it
paints. Finding it at the next launch means the last one never got there,
so that launch runs with GPU acceleration off: a WebView2 that cannot get
on with the graphics driver hangs exactly like one that cannot start, and
this is the single lever that separates them — at no cost on machines
where it was never the problem.
The data folder is created and stays empty, the process keeps running,
and no window appears. Nothing returns, so nothing is logged: WebView2
never hands control back, and a hang has no error to report.
So the ABSENCE of progress is reported. If OnStartup has not been reached
twelve seconds after wails.Run, that is written to the startup log and
shown in a message box naming the two causes — a missing WebView2 runtime
and an antivirus blocking msedgewebview2.exe — because 'OpsLog is not
responding' otherwise sends people to reinstall OpsLog, which is the one
thing that cannot help: the part that has not started is not ours.
Reported from a Windows 10 machine: the process appears, no data folder
is created, nothing starts. There was nothing to read because the only
log OpsLog has lives inside the folder that was never created.
Three exits happen before any window or log exists, and all three were
silent. Another instance already running — correct to refuse, since two
would fight over the rig, but indistinguishable from a crash. The data
folder unwritable — it is created BESIDE the executable, so a copy
dropped into Program Files is refused by Windows outright. And wails.Run
failing, which is where a missing WebView2 runtime lands; its error went
to println, which in a GUI-subsystem program goes nowhere at all.
Each now writes to %LOCALAPPDATA%\OpsLog\startup.log — a folder Windows
guarantees the user can write to, whatever OpsLog was installed into —
and shows a message box naming the fault and what to do about it.
