Tuners not being found; epg not updating

[MaccaHV]

I've just moved this week - when I reconnected the computer and screen, I had trouble getting the cables right.  

1. Now most shows aren't recording - I get [Failed: No errors, but no data delivered. This is usually because the device failed to lock a signal.]  I've only moved 8-10 kilometres but just in case I rescanned for channels.  I've always had 4 Hauppuage tuners, so could record 4 different frequencies at once.  Last night one show recorded and the other two gave the above error message.  I think 2 tuners have stopped working - they can't scan, though still hold the previous channels.  So I've reordered the Devices page to give the two that are working priority.  
   
2. But why didn't two shows record last night?  I feel that the system is remembering which tuner it was to use and if it doesn't work the system simply fails.  Is that possible?
   
3. Is there any way to tell if a tuner has failed?  Or can you only assume no scan means it's dead.  I understand the tuners aren't being made any more.  Any suggestions?
   
4. Do I need to reinstall to get the programme to re-allocate tuners to jobs?  (I really don't want to lose all the pending and recurring shows.
   
5. The other problem is that I can't get it to update the epg.  The internet is definitely connected to the computer, I've streamed the missed shows.  But might NewPVR not be getting the signal?  How can I tell?

Without logs there are no problems so certainly no answers.

Sorry, didn't think of that.

Thought I should run another epg update, in case it was too long ago to still show in the file.
And, BTW, last night I got two recordings, following each other on the same channel, and the other show on another channel didn't record.

The first question I have is why run 6.1.5 when 7.0.5 is available. There have definitely been some tuning improvements since then.

It does look like you aren't getting a signal and you probably need to reinstall the Hauppauge drivers and rescan.

When I try to run the install file I get "Failed to stop  https://nextpvr.com/stable/win64/NPVR.zip Install will not proceed"  If I try again, it thinks about it for a very long time before the download starts.  (I tried it several times.)  Then after it downloads I get the message in the attached.  (The message is long, which is why I haven't tried to type it out.)  I can't get the pdf or word file to attach.  I did a printscreen from the keyboard.  Not having a good day.  I attached the log, so why can't I attach this???
What time zone are you in?

Attachments must be .zip files or images and can't be larger than 2MB.

AI can be your friend

This is a Windows error occurring in NextPVR's update/unzip process. Here's what it means:
The error: The requested operation cannot be performed on a file with a user-mapped section open.
This is Windows error ERROR_USER_MAPPED_FILE (Win32 code 1224). It means the updater is trying to overwrite a file that is currently memory-mapped — i.e., loaded into memory by a running process — and Windows won't allow it.
The call stack tells the story:

UpdateNPvr.ZipHelper.Unzip → trying to extract the update zip
ZipFileExtensions.ExtractToFile → attempting to overwrite an existing file
FileStream..ctor → opening the file for writing fails because...
...the file is still mapped into memory by a running process (likely NextPVR itself, or a .NET runtime DLL it loaded)

In plain terms: The NextPVR auto-updater is trying to replace files while NextPVR (or one of its components) is still running and has those files open/mapped.
Fix:

Stop the NextPVR service before the updater runs (sc stop nextpvr or via Services)
If the updater is supposed to do that automatically, check whether the service stop is actually completing before the extract begins — there may be a race condition or the stop is timing out
Make sure no other process (antivirus, Windows Defender) has the file mapped as well

I will add if DeviceHostWindows crashes which is a v6.15 issue then it might be hard for the installer to help

This time it ran with no problems, after I made sure everything NPVR was closed.  Thanks
Currently running epg update, see if anything changes.  No, still didn't update anything.  I'll reboot.
BTW, I don't remember being asked by windows whether the installer had permission to change the OS.
