Help
Almost everything that goes wrong is one of the things below.
Find yours, or skip to asking a person.
It says my token is invalid or already used
A token works once, on one machine. If you have already
run the installer successfully on this computer, you are done — there
is nothing more to do. For a second computer, or after a reinstall,
request a new
token. Also check nothing extra came along when you copied it: a stray
space or a line break at the end will fail.
The black window closed before I could read it
The installer waits for you to press a key before its window closes, so
any error stays on screen. If the window vanished anyway, your antivirus may
have stopped it (see below). It can also happen if
the zip window was closed while the installer was still running. Run it
again and leave the zip window open until it finishes; or unzip the
download first — right-click it → Extract All
→ Extract — and double-click
setup-langtechdepot.bat in the folder that opens.
Windows says “Windows protected your PC”
Click More info, then Run anyway. This
appears for anything downloaded from the internet that has not been through
Microsoft’s paid signing programme.
It says something went wrong extracting the installer
The download was damaged or cut short. Delete it, download
langtechdepot-windows.zip again, and double-click the
setup-langtechdepot.bat inside the new one.
It says it could not get Syncthing
The installer gets Syncthing through winget, Windows’ own
app installer. Some machines do not have it, and some networks block it.
Download Syncthing yourself from
syncthing.net/downloads
(the Windows 64-bit archive) and take syncthing.exe out of it.
This is the one case where the LangTechDepot zip must be unpacked first:
right-click it → Extract All →
Extract, put syncthing.exe in the folder that
opens, beside setup-langtechdepot.bat, and double-click the
.bat there. It uses the copy it finds beside it.
My antivirus deleted the installer
Some antivirus products remove scripts they have not seen before. Restore
it from the quarantine list, or ask whoever manages the machine to allow the
folder. Tell us if this happens — it is worth knowing which product.
No folders are being offered to me
Give it two or three minutes; the offers do not appear instantly. Then, in
the Syncthing page at 127.0.0.1:8384, look at Remote
Devices on the right. If the depot is listed but disconnected, this
machine cannot reach the server — usually a firewall or a captive
portal. If it is not listed at all, registration did not complete: run the
installer again with a fresh token.
I deleted a file by accident
Nothing is lost, and nothing propagates. Your folders are
receive only, so Syncthing simply flags the difference and
offers a Revert local changes button, which brings the file
back from the server. The same is true if you edit one.
Can I run it again?
Yes. The installer is safe to run as many times as you like — it
checks what is already in place rather than redoing it. You only need a new
token if the machine was never registered successfully.
Can I copy the files to another machine on a memory stick?
Yes. What lands on your disk is ordinary files and folders, not a special
format — copy the tree and carry it. Machines in the same office also
sync directly from each other, so only the first one to get a file pulls it
over the long link.
Asking a person
Reply to the email your token arrived in — it reaches the people who
run the depot. Two things make a fast answer much more likely:
- whether you are on Windows or Linux, and
- the exact text of any error, copied from the window rather than
described. A photo of the screen is fine too.
