Portable version doesn't run

[leaumar]

I downloaded the portable version, unzipped it, copied my installed version's data folder over, removed the installed version, and started the portable version. It worked as expected.

Today I started my computer and synctrayzor came up with the stacktrace at the bottom. When I run it manually, the same thing happens.

The error itself is strange because I'm 100% sure the listed path does in fact exist and I can even copy-paste and run it (leading to, of course, the same thing). No admin rights are needed anywhere in this folder either.

Version: 1.1.10.0; Variant: Portable; Arch: Amd64
Path: C:\Tools\SyncTrayzor\SyncTrayzorPortable-x64\SyncTrayzor.exe
System.IO.DirectoryNotFoundException: The system cannot find the path specified.

Can I see the contents of your log file, please? You'll find it in logs\SyncTrayzor.log. That should tell us exactly what it was trying to do...

[leaumar]

SyncTrayzor.log.txt

Sorry about that, didn't think of adding it

[canton7]

OK so the file it's trying to find is C:\Tools\SyncTrayzor\SyncTrayzorPortable-x64\syncthing.exe: can you confirm that that exists?

You say you've been using it for a while, then it suddenly broke. In order for that to happen, C:\Users\Marnes\AppData\Roaming\SyncTrayzor\syncthing.exe must have been deleted as well. Maybe some antivirus has gone rogue?

copied my installed version's data folder over

Do be aware that a couple of things differ between the default config files for the installed and portable versions. In particular, the installed version will (by default) tell Syncthing to use a data folder in %APPDATA%, and will put a copy of syncthing.exe in %APPDATA%, whereas the portable version will put both in the data folder inside the portable install dir.

It doesn't affect this issue, but something to bear in mind.

[leaumar]

config.xml does indeed contain this though:

  <SyncthingPath>%APPDATA%\SyncTrayzor\syncthing.exe</SyncthingPath>
  <SyncthingCustomHomePath>%LOCALAPPDATA%\SyncTrayzor\syncthing</SyncthingCustomHomePath>

I'll fix these paths and let you know in a minute, but in the meantime, isn't it strange the config points to a different path than the one it's failing on?

[leaumar]

changing the paths to this fixed it:

  <SyncthingPath>syncthing.exe</SyncthingPath>
  <SyncthingCustomHomePath>data\syncthing</SyncthingCustomHomePath>

So really the question is why does the popup talk about a different, even invalid issue instead of the real problem? :P

[canton7]

The dialog just contained the path to SyncTrayzor.exe - that's fine. It's slightly confusing that it happens to be next to an error message which talks about paths, but the whole thing's supposed to be reported on here anyway.

Those should be %EXEPATH%\data\syncthing.exe and %EXEPATH%\data\syncthing, otherwise things will break then starting SyncTrayzor from stuff like a shortcut.

Either way, that shouldn't have caused your issue... %APPDATA%\SyncTrayzor\syncthing.exe just specified a path to copy syncthing.exe to (so "your" version isn't overwritten by upgrades which SyncTrayzor does). Did you perhaps delete the folder %APPDATA%\SyncTrayzor?

[leaumar]

I did, yes.

I guess it makes sense now. The config referred to the old appdata path and that no longer existed, and the error message didn't actually specify the path it was failing on.

Thanks for the solution :)

[canton7]

You have highlighted a bug though: I should ensure that the path to copy syncthing.exe to exists before I try and create it. Normally it's not an issue, as by default it refers to a path which SyncTrayzor creates anyway, but when users decide to customise things...

[leaumar]

Customise? I honestly just wanted to go from an installed copy to a portable one, and the instructions said to copy the data folder, and only that. I didn't touch the config or anything.

Sure, the instructions are for upgrading portable versions, not switching variants, but I figured it was closely enough related.

Anyway, glad we found the problem then :)

[canton7]

It's effectively been customized, since the path isn't what a default installation would give you. Don't worry, the reason it's in the config file is so that people can change it.

I don't think I have instructions on converting from an installed version to a portable one?

[leaumar]

I only saw them for upgrading between portable versions, yeah
