Downloader Cannot Open File

[Foxlider]

I am having a few issues with files sometimes. It seems the downloader tries to access files that are already opened or access them twice (but I might be wrong).

The odd thing is that the file doesn't appear to be opened at all. When using handle.exe from SysInternalsSuite the file is not flagged as opened

What's the exception type being thrown? And is this the entire stacktrace?

[Foxlider]

The main exception is an Aggregate Exception

It has an InnerException though The exception is a System.IO.IOEception

Whats the message of the IOException? Access denied?

[Foxlider]

Sorry I forgot to include the message again

Error: One or more errors occurred. (The process cannot access the file 'E:\16aa_PUBLIC_USER\!Server_Files_1.8\arma3server.exe' because it is being used by another process.) Inner Exception: The process cannot access the file 'E:\16aa_PUBLIC_USER\!Server_Files_1.8\arma3server.exe' because it is being used by another process

It happened to an user who downloaded files from a depot, switched depot branch, updated and switched back to main branch before updating again and got the error.

I keep haing the error while downloading the ace arma3 mod. Seems pretty random

[RyanTT]

I couldn't really determine what might be the root cause of this. As it appears to be failing during the verification already (and since verification does not have a lot of complexity to it), please check that the file is actually not protected at the time of trying to update it. Simplest way would be to have this library error out with this exception, and then without closing anything, just trying to delete the files in question manually via explorer to determine if there truly is no open handle on it. Right now I don't have any idea what this might be I'm afraid

[Foxlider]

That's my point. No file handle seem to be locked and I could delete the folder without issues.

Hm. Does this happen on first attempt to update after opening the program, or perhaps only after the second attempt (after the updater has already checked/touched these files once)?

[Foxlider]

It keep happening all the time but usually it's always the same file.
