Should Official V5 Build Upgrade/Replace V4?

[Graham]

Does the line in PostProcessing.bat "set NSHelper=C:\"program files (x86)"\npvr\nscripthelper.exe" get changed to "set NSHelper=C:/Program Files/NextPVR/nscripthelper.dll" now?

Martin knows it all ... https://forums.nextpvr.com/showthread.ph...helper.dll

Thanks Graham, so once I install the runtime then the script can call that .dll directly with this line: "set NSHelper=C:/Program Files/NextPVR/nscripthelper.dll"

Not quite ... you need a ... dotnet ... command to call the dll ... something like ... "set NSHelper=dotnet C:/Program Files/NextPVR/nscripthelper.dll" ... I'll let you experiment with quotes in the set command to work around the space after dotnet ...

Nevermind. A reboot fixed this> Hmm, now V5 can't find my HD HomeRun Prime, though my channels now appear in the channels list. The tuner was showing in the list of devices before I copied config.xml and npvr.db3 over. Rescan For Devices doesn't appear to do anything.

Post the logs and I'll take a look.

Hi Sub, it might have just been confused by me copying over my old config.xml and npvr.db3 files.  Restarting the browser didn't help, but rebooting the system did.  I'm adding the log file below, in case it will help you determine why the HDHR Prime seemingly vanished.  Note that a HD HomeRun (not prime) was showing up in the list.

Yep, seems to have been related to that. Its got a missing database table.

Did you copy the npvr.db3 over while NextPVR was running, then not restart NextPVR? I think it came right at the reboot, since NextPVR was restarted, and it adds the missing table.

I didn't think to stop and restart the NPVR service, I only stopped and restarted the browser. So that one was self-inflicted.

Posting this here as a guide for others that want to move from V4 to V5.      (Sorry about the formatting.  It seems that the forum software discards tabs).

Migrating from Version 4 to Version 5 on Windows

This guide assumes that you already have version 4 running and configured on your server PC.  These are the steps that I took to make the move from V4 to V5.

Before starting, I made an image of my boot disk, just in case...  I use the free version of Macrium Reflect to make the image.  Available here: https://www.macrium.com/reflectfree
You could also copy the entire folder C:\Users\Public\NPVR to a safe place.

Next I uninstalled Version 4 using Windows Add or Remove Programs

Downloaded and ran NextPVRSetup.exe (Found here:  https://nextpvr.com/NPVRSetup.exe)  This goes to the NextPVR repository and installs the latest and greatest version that sub has posted.

After V5 installed, I copied my old config.xml and npvr.db3 files from C:\Users\Public\NPVR in V4 to C:\Users\Public\NPVR-data\ in V5.

To copy over an existing Comskip configuration - I copied the entire Comskip folder from C:\Users\Public\NPVR\,to C:\Users\Public\NPVR-data\

Copied PostProcessing.bat, PostUpdateEPG.bat and UpdateEPG.bat from C:\Users\Public\NPVR\scripts to C:\Users\Public\NPVR-data\scripts

Edited PostProcessing.bat and changed:
cd C:\Users\Public\NPVR-data\Comskip  to:
cd C:\Users\Public\NPVR\Data\Comskip

NScriptHelper has changed from a .exe file to a .dll.  To deal with this, the pointer for NScriptHelper in PostUpdateEPG.bat had to be modified:

"c:\program files (x86)"\npvr\nscripthelper.exe  to:
set NSHelper=dotnet "C:/Program Files/NextPVR/nscripthelper.dll" -isinuse -pin:xxxx

Note that for the "set" line to work, you will first need to install dotnet from Microsoft, availble here:  https://dotnet.microsoft.com/download/do...nt/runtime

Here's a PostUpdateEPG batch file that checks to be sure that no recordings are in progress, then reboots the system once the system is not busy recording (Replace the xxxx with the access PIN for your server.  The default is 0000):

echo off
REM Reboot if not recording
cd C:"\Program Files\NextPVR"
set NSHelper=dotnet NScriptHelper.dll -isinuse -pin:xxxx 

:check
FOR /F "tokens=*" %%i in ('%NSHelper% -isinuse') do SET condition=%%i
echo %condition%
IF %condition% =="NOT RECORDING" goto reboot

:delay
timeout 60
goto check

:reboot
echo "About to reboot"
shutdown /r

To get channel icons for the TV Guide screen, open the NPVR web page http://127.0.0.1:8866/ then click Settings (top right corner) -> Guide (left sidebar).  Now click on the "Download Channel Icons" button under the EPG Sources section.
