old zip file causes error

[ghost]

I noticed that one client was failing to update and the reason was an old zip file. Looks as if the updater will use it, if it has the correct name. Unfortunately it had a file inside that was not suppose to be and I got a "Archive entry cannot be linked to a file in the configuration".
What is the reason for reusing existing files, maybe reducing download time? Maybe deleting unneeded files would make sense.
Of course, I can always just delete all zip files before starting an update. Any thoughts from others?

The zip entry is always deleted after a successful update. The zip file itself is also deleted, unless you call Archive.install(false).

The reason a file might stay behind is if you download the update but never installed them.

I do use the true parameter, but it seem that the update failed, so archive was not deleted and is used next time.
I will add a deletion of an old archive before downloading a new version to ensure this will not happen again. thanks for the info.

Or perhaps try again to install before deleting and downloading again

I am retrying 50 times. But I got access exception.

Your file if open in a different process I guess

I thought so too, but no. I made sure suing Process Explorer. I never found out the reason.
