Fusion no longer loads since Jan. 19th update

[kb9ydn]

Starting with the January 19th update I'm having problems getting Fusion to start.  It worked the first couple times but now I usually just get the splash screen and nothing else.  Eventually I have to kill the process from the task manager.  If I do this enough times occasionally it will start, maybe 1 out of 8 attempts?  It's hard to say.  Sometimes it will get to the main window but is unresponsive from there.  There are no crash reports because it never crashes, it just locks up.

I'm running Windows 10 on a fairly new Pentium G4400 with 16GB RAM and 240GB SSD.

The main log file is attached.

Hi @kb9ydn,

Have you tried to re-install Fusion?

If you have an Anti-Virus, it is a good idea to turn it off as well!

I was hoping to avoid reinstallation but I'll try that if I have to.  I'll wait and see what AD says first.

No antivirus either beyond what comes with Windows 10.  If this were the problem I would expect it to be consist and always not work.

On one of the occasions I did get it to start I tried logging off and back on.  No change.

One thing I have noticed is that starting it from the desktop icon seems to work more often than starting it from the quick launch bar icon.  They are both pointing to the same file so I can't see why this would make a difference.  And it's possible this is just random chance.

I'm on Win10 as well, but I re-installed my machine a month ago and since then no problems. To me, it sound like something when wrong with the update and it could happen.
If you upgraded (not a fresh installation ) to Win10 or the last clean Windows installation was done more than a year ago, then you should try reinstall Fusion and consider reinstall your Win10.

Hi @kb9ydn,

Found the issue from your logs, thanks for posting! From them, I can see:

• adsk.dls.streamer.exceptions.LockedRegistryByKnownReason: This process failed because of another installer doing cleanup in process
• apsw.BusyError: BusyError: database is locked

The first error is rather simple to fix. A restart of your computer should kill that extra process that is running (or you can look for streamer.exe in task manager and kill it that way.

The second error, I am afraid normally points to needing to reinstall. However, this should be a quick process as we do not need to completely uninstall. To do this:

• Enable hidden folders from Control Panel
• Navigate to C:\Users\Chris\AppData\Local\Autodesk
• Delete the Web Deploy and Web Services folder.

Once deleted, please reinstall Fusion 360 from this link here. When you go to reinstall, please right-click the file and select "Run As Administrator". Sometimes, lack of administrative privileges can cause the database table to be locked.

Thanks,

[kb9ydn]

So I tried the reinstall using the instructions above.  At first it seemed to work but now it's back to hanging up again on startup.  I should also mention that I have this problem on two computers; one is my desktop at home and the other is my laptop at work.  I have a job coming up soon that's going to need Fusion so I really need to get this sorted out.  Any other suggestions?

Hi,

Can you tell us what you are seeing when you try to launch Fusion? It is hanging somewhere specific?

Can you see if renaming your NMachineSpecificOptions.xml and NGlobalOptions.xml files help?

Presuming your on the Windows platform the path is:

c:\users\username\appdata\roaming\autodesk\neutron platform\options

Regards,

Hi @kb9ydn,

At what phase of launch does Fusion start having these issues. It is very strange that 2 computers on 2 different networks are having the same issues. Just to check - does it seem to be after you log into your Fusion account that this starts to happen? Regardless, for time sake, feel free to private message me and we can set up a time to chat and do a screen share session. I would love to get a first hand glance as to what is going on! Also, please feel free to ping me here when you do - I know that the message system was not giving email notifications for a little bit so I want to ensure that I see your message!

Thanks,

Yesterday I decided to try an experiment, by starting and stopping Fusion 10 times in a row to see what would happen.  First I rebooted the computer to ensure a fresh start.  Then I Loaded Fusion using the icon in my quick launch bar and recorded what happened.  If it loaded correctly I would close it with the close window button in the upper right corner.  If it hung up I would kill the Fusion process tree from the task manager.  Between tries I would wait 20 seconds or so to make sure all Fusion processes were fully terminated.  The only other application running was the task manager so that I could kill Fusion if it locked up.  This is what I got:

(My home computer)

1) started normally
2) started normally
3) started normally
4) main window came up but was unresponsive, waited maybe 30 seconds and then killed the Fusion process tree
5) started normally
6) Fusion hung up at the splash screen, waited maybe 30 seconds and then killed the Fusion process tree
7) started normally
8) main window came up but was unresponsive, waited maybe 30 seconds and then killed the Fusion process tree
9) main window came up but was unresponsive, waited maybe 30 seconds and then killed the Fusion process tree
10) started normally

Then I tried the same thing on my laptop at work, and got this:

(Work laptop)
1) started normally
2) main window came up but was unresponsive, waited maybe 30 seconds and then killed the Fusion process tree
3) started normally
4) started normally
5) started normally
6) started normally
7) started normally
8) started normally
9) started normally
10) started normally

Obviously this problem is quite random and inconsistent.  Since it doesn't seem to happen very often on my work laptop (which is where I really need it) it's not as critical as I thought at first.  Once it gets started it seems to operate normally so I can at least get my work done.  I'm attaching another log file here from my home computer, taken immediately after the 10 trial start test.  Also there is a screenshot of what the unresponsive main window looks like.

I did also (after the 10 trial test) try renaming the config files as suggested by @baribak above.  That didn't seem to make any difference.  @James.Youmatz When I have more time I'll see about arranging a chance for you to remote in and take a look at what's going on.

Thanks for the help so far.

You need to kill screencast as well

I figured I should come back and update this thread.  For whatever reason the issue seems to have resolved itself, at least for now.  I haven't had the lock up problem in weeks and have since loaded Fusion many times on both computers.  So I'm going to mark this one as solved, even though the root cause was never found.
