Greetings,

I recently discovered that I am starting to amass a list of WUs that are listed as status: 'Error while downloading'. Here is just one example from the list.

I check my WU list every day and, until the past few days, have not seen this type of error before. Can someone explain what may be the problem, and if it is on my end, so that I may attempt to put a stop to these errors?

The only major thing I have done with this PC was to upgrade to Win10 Pro 64bit, run it for 3 weeks, then revert back to Win7 Pro 64bit. I have noticed at least one anomaly in Win7 since reverting back, the Start menu is not quite the same. I'm thinking that Micro$oft stuck in some overt changes to annoy users and try to force then back to Win10. I would not put it past them to do such an underhanded deed. ;)

Anyway, if I can get a little help in trying to resolve these errors, it would be greatly appreciated. Thank you in advance. :)

Keep on BOINCing...! :)

[edit] Adjusted for the exact verbiage of the error. [/edit]

Hi Siran, how did you revert back to windows 7?
Did you do a "fresh install"?

I was getting tons of download errors recently when one of the servers was down. Cleared up when it was brought back into service, but after the network reorganisation at Berkeley I also stopped BOINC and did a DNS cache flush where possible, and restarted.

Hi Siran, how did you revert back to windows 7?

Greetings,

Easy, do this: Go to Settings/Update and Security/Recovery. Click 'Get Started' under 'Go back to Windows 7' or 8 or 8.1.

1. A blue window will pop up with a check box list of reasons for going back, select all that apply and enter any note you want to send and click 'Next'.
2. Another blue window will pop up with a short list of 'What you need to know', click 'Next'.
3. Another blue window with a message that 'You'll need your old password', click 'Next'.
4. Another blue window with a message that 'This might take a few hours', click 'Next'.
5. Another blue window with a message 'Thanks for trying Windows 10', click 'Go back'.

You will get a blue screen saying 'Restarting'. After which you will get a black screen saying 'Restoring your previous version of Windows...'. The process did not take 'a few hours' like they say. I believe it was about 10 or 15 minutes tops for me. After the recovery process you will be booted into your previous version of Windows. And... that's it! :)

So far I have found a couple anomalies with going back to Win7, something changed with the Start Menu and a couple desktop icons changed. I may research doing a repair install of Win7. I had done a fresh Win7 install only a few weeks before checking out Win10.

Keep on BOINCing...! :)

Greetings,

I'm still finding WUs with status 'Error while downloading', such as this one.

I have cleared the DNS cache which I don't believe may have had any affect.

Any other suggestions?

Keep on BOINCing...! :)

Reinstall driver for network.

I doubt that it is your network "card" driver, much more like a problem with the AV software or Widows Marware that is screwing up the download.

Greetings,

I finally caught one that would not cause me to spend a great deal of time searching for it in the BOINC Manager log. This is information on the latest error:

8/28/2015 5:13:48 AM | SETI@home | Started download of 01no11af.3884.20599.438086664203.12.139

I cannot see this as being caused on my end, well, ok, it is, but not by my system or anything. Unless rolling back to Win7 from Win10 did something else not known to Win7 by the roll back process. I really would not put it past Micro$oft to sabotage a previous version of windows simply because a user does not like Win10 and does the rollback.

There are no problems with my drivers, no problems with my AV software and I have no idea what 'Widows Marware' is. ;)

I really would like to get this resolved. Would re-installing BOINC be a viable option to fix this? I'm not running 7.6.6 or whatever it is because of some bug or problem with it. I'm still running 7.4.42 (x64).

I hope this new information sheds a bit more light on what to do to fix this. :)

Keep on BOINCing...! :)

Siran I have had 1 unit today give the same error below is the strr file , I have looked at the unit's strr file you put up and it says the same as the units I have in error for same reason

http://setiathome.berkeley.edu/result.php?resultid=4342921588
This link is the unit I am talking about and it's strr file

http://setiathome.berkeley.edu/result.php?resultid=4340298701
This link is your Unit that error'd and the strr file you will notice they are the same

What has cause'd it to happen to me was a faulty 24 pin main power plug . It keep'd restating the machine every 20 mins or less I think it's pin 14 and 15 not making a good connection as I have had to use the PSU to power another device and so it meant I had to short pin 14 and 15 to get it to start the PSU up with a paper clip

It may also happen because your connection went down or there is a problem with your I.S.P .

other wise if your machine is not restarting you may have some other faulty equipment on that machine or maybe your PSU is on it's way out

Greetings Glenn,

Thanks for the reply. :)

This only started after I rolled back to Win7 Pro 64bit from Win10 Pro 64bit. This didn't even happen when I was running on Win10.

The Motherboard, CPU and graphics card are all new. The PSU is about a year old. That's not to say that something could not have gone faulty now. The PC does not restart on it's own and I have it on a UPS.

I have a diagnostics tool for my HDDs and I have Memtest86. I'll run some more diagnostics to see what's up, if anything.

When I rolled back to Win7, I noticed a couple of anomalies. One is that 2 programs, one was MalwareBytes the other GPU-Z, were gone. They were still installed when I updated to Win10. Why they were gone on the rollback is beyond me. The other anomaly I know about is in the Start Menu. Notepad is listed at the top with a right arrow for pinned documents and recently opened. That no longer works. I have to rely on the 'Recent Items' link to open documents I deal with daily and monthly. For all I know, there could be 100 more anomalies that I don't know about, crap that Micro$oft did to my Win7 install to get me back to Win10.

I don't know, I'm thinking that Win10 has/had something to do which causes these WUs to error out on the downloads. If you have any other thoughts on this, please let me know. I don't like these errors.

Keep on BOINCing...! :)

Have you done an sfc /scannow under the admin command prompt?

This will test your win 7 image.

Siran I would say it's your win10 roll back to win 7 . Your not the only one that has had trouble after doing that .

A clean install of win 7 might be the only way to fix it . However that will depend on weather you have a product code you can use to reinstall it or it's a 1 licence use

This probbally wont work can you restore it back to a earlier time now you have rolled it back . If not then any thing else I could suggest would be very complicated to explain here to get windows to restore it back to normal

Aka: going into windows folder and deleting files in the system folder and windows root folder to get windows to reinstall it

not shore how well it would work thou

Thanks for the reply! :)

I just ran the scan. Here are the results:

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations.

But, that's not to say that whatever the rollback may have done didn't fix it so that there are no violations. ;)

It was worth a try.
Did you reinstall boinc, yet?

Just one more silly thing to try(if you have not done so, already)

Power down your router and modem and restart.

Greetings Rasputin42,

Good idea, I will do that tomorrow. I haven't reinstalled BOINC yet. If the modem and router doesn't fix it, I will do BOINC next.

Greetings,

Well, it's looking more and more like I will be doing a repair install of Win7. Nothing I have done seems to fix whatever Win10 screwed up. I'm still getting WUs that error on download. The biggest negative about the repair install is that I will have to do the update shuffle again. I do have my trusty Notepad list of the updates to get rid of.

I just had a thought: Do updates that are marked as 'hidden' stay hidden or will they reappear after the reinstall of Win7?

I believe I will be going through this thread and adding more stuff to my Notepad document. Things like links to sites that show how to stop telemetry and tracking stuff.

Yes, I know, some will ask how I know Win10 screwed up Win7. Well, the answer is this: I did not get any of these errors with Win7 before upgrading to Win10. I did not get any of these errors after upgrading to Win10. I DID start getting these errors after doing the role back to Win7 from Win10 and I am still getting them. If, however, I still get these errors after doing the repair install of Win7, I may have to do a complete clean install of Win7. And, if I still get these errors after that, I will no longer blame Win10 and will start looking elsewhere for any problem(s) with this PC.

I have done the suggestions made here and nothing seems to help. It is time for some drastic measures. ;)

OOPS! There is one thing I forgot to do, I forgot to reinstall BOINC. I will do that and see if that stops the download errors.

[edit] BOINC Manager v7.4.42 (x64) has been reinstalled, well actually it was a repair install. I may have to wait a day to see if I still get the errors. If I do, I will remove BOINC and do a clean install. [/edit]

Keep on BOINCing...! :)

Have you investigated the actual downloaded files, to see what might be wrong with them? Are they the right size (usually 367KB, perhaps 368KB)? Can you use one of the available online utilities to check the MD5 checksum - does it match either what BOINC expected, or what it found? Do the contents look like a normal workunit?

If you find out what's wrong with them, you might have a better idea of which part of your system needs cleaning up.

Greetings Richard,

Huh? ;)

Somewhere in this thread I posted what the BOINC event log said which was that the MD5 check expected one checksum but was presented with a different one. As for what a WU content looks like, I would not know even if someone pointed and said "This is what the content of a WU looks like". ;) I didn't even know I could look at the contents.

So, I guess the answer to your question would be 'no'. ;) Well, except for looking in the event log... :)

'I'll be back...'
[edit]I looked at the first 5 in the error list here and none of them are on my system any longer. I presume that the rest are not either.[/edit]

'expected' 0206a1a834822fa5a40ad92e62cf7969 is a checksum (MD5) calculated on the server - it's passed to your computer when the task is issued.

'got' c230fe3bf5431e59785cb4be7029a195 is the checksum calculated by your copy of BOINC, based on what ended up on your hard disk. Clearly, they're different, which means that the file you ended up getting (after the download) is different from the file the server thought it was sending. It's unlikely to be a server problem (otherwise, we'd all be getting them), so it's likely to be something to do with whatever happened to Windows: a clue. Hence the questions.
