Can't start service NPVR Recording - Windows 8.1 PRO 64-bit

[locanda]

Windows 8.1 PRO 64-bit, SiliconDust HDHomeRun Dual-3 (clearQAM on Time Warner Digital Cable (basic channels), latest version of NPVR with patches applied. Firewall allowing NDigitalHost, NextPVR, NRecord.exe, private & public.

Actually, I can now get everything else to work, as long as I use Administrator Command Prompt to run "NRecord.exe RUN" before starting NVPR. Device is configured, Channels scanned. I can view LiveTV, and did a test record of 2 Manual Recordings at the same time (thru the dual tuners). All functions seem to be working. I still need to work on the EPG, maybe remap channels to #s I'm used to, and play around with closed captioning to check that.

However, unless I use the Command Prompt, I cannot start the NPVR service from the start menu. Instead, I will receive the error message:

"Unable to start service: System.InvalidOperationException: Cannot start service
NPVR Recording Service on computer ".".--->
System.ComponentModel.Win32Exception: The system cannot find the file
specified
--- End of inner exception stack trace ---
at System.ServiceProcess.ServiceController.Start(String[] args)
at NCtrl.Program.Main(String[] args)

Logs attached to this message.

Did you change the user account for the NPVR Recording Service? Make sure it is set to "SYSTEM" or that the user has access to the NPVR install folder.

[locanda]

I'm the only user, and have set ownership and permissions for all.

The STOP NPVR service works fine.

If I can't resolve otherwise, is there a way to 1-button batch invoke the Command line to start the Recording Service, then launch the NPVR application?

[johnsonx42]

admin command prompt;

Code:

sc delete "NPVR Recording Service"

then re-install NPVR

[locanda]

admin command prompt;

Code:

sc delete "NPVR Recording Service"

then re-install NPVR

What's the reasoning behind this suggestion? I'm also guessing this is in response to the initial problem, and not to my subsequent request about a batch workaround. I had previously (many times) uninstalled NPVR (and removed remaining files, directories, and registry entries) and re-installed. If there's a useful purpose to deleting this particular service and re-installing the NVPR package (and patches, I presume), without uninstalling the rest (over the existing installation), how would my current settings be affected? Do I go through config, scans, channel edits again?

i'm simply surmising that something is wrong with the way the service got installed in windows, so deleting the service and re-installing may fix it. otherwise I have no idea why you can't run NRecord as a service but can run it from a command prompt... usually the only reason for running it from a command prompt is to get diagnostic output to figure out why it won't start up. no, doing this won't change your configuration at all, in fact it won't even undo your patches since the installer won't replace newer files with older ones.

as to your second request for some batch workaround to start NRecord and NextPVR together, I don't see the point. even if we accept that for some bizarre unique reason your system just can't run NRecord as a service (making it the only known one on the planet with such a problem), then putting NRecord RUN in your startup group would be a far more reasonable workaround.

You are as a GOD. Deleting the service and a re-install worked.

I did some experimentation prior to that. No problem running from a regular command line (although I guess if I've get Admin privileges, it was probably just the same as running from the (Admin) command line. If I didn't use RUN after the NRecorder.exe, then I'd get the message:

"Cannot start service from the command line or a debugger. A Windows Service must first be installed (using installutil.exe) and then started with the ServerExplorer, Windows Services Administrative tool or the NET START command. BTW, too many copies of installutil.exe around, and navigating directories in the command prompt window is a pain. NET START didn't like the name of the service "file not found". Too me, that definitely pointed to a problem with the installation of that particular service, now fixed by your suggestion. Thanks.

Now, if I could only get .NET Framework 3.5 to install without an 0x8007002 error...

Also, for some reason this (U.S.) Volume License version of Win 8.1 PRO 64-bit has no Add Feature function, so I couldn't even buy Microsoft's $10 Media Pack for Pro, but maybe now I won't need it.

Are you trying to install it from the <Turn Windows Features on or off> in the Control Panel or from a stand alone installer. The later will not work in Windows 8 or 8.1.

If it is from the Control Panel then maybe it is time to run DISM to repair your Component store.
From a command prompt run:

Dism /Online /Cleanup-Image /StartComponentCleanup

followed by:

Dism /Online /Cleanup-Image /RestoreHealth

The first command cleans up the component store, (WinSxS Folder) reducing it size and removing old entries.
The 2nd command is used to repair corrupt files and corrupt entries in the component store.

Follow that by running SFC /SCANNOW.

[locanda]

Good try. Ran those all successfully, but still cannot enable .NET 3.5 from the Control Panel.

I was just about to give you a link to msanswers - then realized it was your thread!

Do you have any language packs installed? You have to install them after .net.

Have you tried mounting the Installation iso or inserting DVD then running.

"Dism /online /enable-feature /featurename:NetFx3 /All /Source:<drive>:\sources\sxs /LimitAccess"
Obviously changing <drive> to the drive letter of your media

If that doesn't work, about the only thing left I can think of to try is a repair - I think it is called "refresh" install
