Interesting. Does this happen every time, or was it a one-off? Can you please check whether these folders exist?

• C:UsersnameAppdata
• C:UsersnameAppdataLocal
• C:UsersnameAppdataLocalTemp

[LadivItnas]

Yeah all of those folders exist sorry for the late reply

[HebaruSan]

Thanks, what about C:UsersnameAppdataLocalTempCdFileMgr ?

[LadivItnas]

Oh no it's not there

[LadivItnas]

How do I get it back there?

[HebaruSan]

That's quite strange! The Transactions library attempts to create that folder if it doesn't exist:

https://github.com/rsevil/Transactions/blob/8125415d5a74eb129d2d0311762362dfa2679193/src/ChinhDo.Transactions.FileManager/TxFileManager.cs#L16-L22

https://github.com/rsevil/Transactions/blob/8125415d5a74eb129d2d0311762362dfa2679193/src/ChinhDo.Transactions.FileManager/Utils/FileUtils.cs#L8-L20

As far as I know, there is nothing that would stop that call from succeeding, since you would always have access to your own AppdataLocalTemp folder. Maybe one of those Windows Defender type things?

You could try creating the folder yourself in Windows Explorer:

1. Open C:UsersnameAppdataLocalTemp
2. Ctrl-shift-N to make a new directory
3. Type CdFileMgr to set the name
4. Press enter

Creating the folder seems to have fixed it (even if it's empty)
Thanks!

[GargamelKSP]

Even after creating the folder previously, I added 2 new mods today, and it threw this error again. Manually adding the folder fixed it, again. Adding and removing previously cached/installed mods did not trigger this error.

[HebaruSan]

Thanks, @GargamelKSP, that's a helpful clue. It means that something is _deleting_ the folder, not just failing to create it.

Can you please check whether you have this "Storage Sense" thing turned on, and/or "Delete temporary files that my apps aren't using"? Maybe Windows 10 is deleting it in a scheduled background task:

[GargamelKSP]

Nope, had to check, but it's turned off.

[GargamelKSP]

Downloading and installing new mods while CKAN is still open from a manual fix earlier, error is not thrown.

[GargamelKSP]

Closing Ckan, reopening it, and DL and installing new mods also did not throw an error this time. Previous (second) error was after a reboot.
If you need any other testing, ask.

[drewcocker]

Running CKAN in administrator mode fixes this for me.

Running CKAN in administrator mode fixes this for me.

Why would you do that? Do you not care about your PC becoming part of some bot army, using up all your CPU resources?

[linuxgurugamer]

I haven't looked at the code that much, but:

It only checks to see if the folder is there when the TxFileManager is created. But this happens hours after it was created. I'm guessing that it creates it when you first go to the web, and relies on it being there for the duration of the session

[HebaruSan]

Good call, so maybe we can work around this by changing how and when we create TxFileManager objects. A search turns up several that are private static readonly, which should possibly be shorter-lived and only created as needed...

[linuxgurugamer]

I'll leave it in your hands

[linuxgurugamer]

Suffice to say, I would really like to see this fixed. It's very annoying to have to close and reopen CKAN every few hours
