Unexpected error starting web server

[MrReis]

NextPVR web server will not start. This started to happen while Windows was changing the indexing properties on all files on the C drive (where NextPVR is installed). I have completely uninstalled and reinstalled NextPVR (3.8.3.160929) which does not help. The Windows event log states "Event ID 1325 from ASP.NET.4.0.30319.0 cannot be found. Component is not installed or the installation is corrupted." I can't figure out what is "not installed" or what "installation is corrupted." It can't be NRecord.exe since I completely uninstalled and reinstalled NextPVR.

Can anyone suggest a way to find out what is not installed or corrupted?

At the time of the error the NRecord.log shows the following.

Uninstalling doesn't delete the temporary web server files. I would stop the recording service and delte

Code:

C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root

and restart.

Thank you for your suggestion Martin.

I (1) stopped the recording service, (2) deleted everything (directories and files) under "C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root" and (3) started the recording service.

NextPVR web server will still not start with the same error in NRecord.log

Does it start after a clean boot? I remember on Windows Server 2012 user where it'd only run once after each reboot. Never did work out why this happened for him.

I performed a "clean boot" (per https://support.microsoft.com/en-us/kb/929135 for Windows 10) with the exception of disabling nTray.exe. NRecord.log shows that NextPVR web server still does not start.

Can you suggest any diagnostic software that would help identify the problem?

[sub]

Odd. I'm not reallly sure what might be causing that.

[mvallevand]

I read threads that error can be related to Drive Compression. I makes sense since the Web Server runs in C:\Windows and compressing the system folder has never been recommended that makes some sense.

I removed NTFS compression from the C drive and suddenly NextPVR web server can now start.

The system (that does not allow NextPVR web server to start with NTFS compression) is 64-bit Windows 10. I have the same exact NextPVR setup running on a 32-bit Windows 8.1 system with NTFS compression and NextPVR web server is able to start just fine. Go figure.
