Unable to locate program: FantasyGroundsUpdater.exe

I started FGU, clicked on CHECK FOR UPDATES, the updater started and I got busy entertaining myself in a web browser while the download process started. I noticed that the updater snapped closed - so I relaunched FGU and now get:

It would be nice if the updater were available for download rather than reinstalling over the top of FGU.

Thanks

Check your FG data folder for an update named something like ...PREV

The updater creates a file folder called FGudpater_New and then tries to delete the old updater (which it renames FGUpdater_Old) but this can fail and so the process halts. If you delete the _OLD one and replace it with the updater in the _NEW folder and run it, it should carry on fine.

Ok, I located the _NEW one and copied it over. Thanks, guys!

@Topdecker,

* What OS are you using?
* When was the last time you updated prior to this time?

I want to pass this on to Ryan to review.

Thanks,

One of my players and I both saw this same error message when I was running my game last Thursday. (windows 10, unsure of previous version, perhaps up to two weeks?)

edit: One thought that occurs to me is that when I've seen this issue it immediately follows an update, and during the update the "Launcher" seems to be patched first, then FGU should restart prior to updating all the the modules. However, it seems like FGU closes but doesn't auto-restart. So I have to launch the program again, and run the Check for Updates again, which then patches all the modules. Perhaps the same bug which causes the restart to fail is also causing an incomplete patching process?

In my case when I looked at the updater log the reason it stopped was a permissions issue (it couldn't delete the old file before continuing). I would have reported it at the time but I knew it was being worked on so I just assumed that this was part of the problem and you knew about it. Should perhaps have not assumed that.

The only odd thing to transpire is that last week, I installed over the top of my existing install to handle the problems that were going on then with updates.

I have seen this issue crop up before, but it is difficult determining exactly why the file can't be deleted and what's a good way to resolve this.
As far as I can tell for this specific issue, FGUpdaterEngine is doing its work properly, launching FantasyGroundsUpdater_Old.exe properly (which does the legwork of removing the old updater files and copying in the FantasyGroundsUpdater_NEW).

There are 3 things this program is deleting: FantasyGroundsUpdater.exe, FGUpdaterEngine folder (containing FGUpdaterEngine.exe), and if/when those complete properly, the FantasyGroundsUpdater_NEW folder.

The code in FantasyGroundsUpdater.exe is set to wait until the FGUpdaterEngine process closes, so it *shouldn't* be an issue of the program being open.

If anyone does happen to come across this issue and has FantasyGroundsUpdater.log in their Application folder (particularly with any messages about failed deletion), I would appreciate that.
This would at least give me insight into which deletion is problematic, and then to figure out why. I'd guess that some file is being accessed and not released properly, but it's tricky to know.

I'll check if anyone's had a similar issue with a log already.

Just had this issue again.

Everything worked fine after I copied the "new" updater from the folder to the main directory.
