V5 install failure

[petergriffiny]

If you download https://nextpvr.com/stable/win64/NPVR.zip and unzip it into "C:\Program Files\NextPVR" as admin the installer will give the zip error but continue to do the install.

Can someone create a c:\temp, and collect the c:\temp\install.txt after a failed install?

Sure

Code:

The reason I posted it was a tls error was that is what Wireshark said and when I tried curl

Code:

curl --tlsv1.0 https://nextpvr.com/stable/win64/NPVR.zip
curl: (35) schannel: AcquireCredentialsHandle failed: SEC_E_ALGORITHM_MISMATCH (0x80090331) - The client and server cannot communicate, because they do not possess a common algorithm.

--tlsv1.2 works.

I've updated http://nextpvr.com/NPVRSetup.exe to correct this.

If you try, and still see the same issue, it's likely because your browser is just using the same version it previously downloaded. You can force it download the new version by using a url like http://nextpvr.com/NPVRSetup.exe?x=2

[mvallevand]

That works for me and Wireshark says TLSv1.2

I think it is failing on tls handshaking, only tls 1.2 seems to be supported on the server.

I'm not really sure what changed to prompt this (windows update, or apache on the server), but yes it was related to this. I basically had to enable tls 1.2 support in the code that downloads the NPVR.zip.

The server has tls 1.2 enabled, and the older depreciated disabled (tls 1.1/1.0, SSLv2/SSLv3), which follows recommendations. tls 1.3 is not currently available on centos 7, so can't be enabled.

[mvallevand]

I didn't see any TLS 1.0 Cipher Suites on https://www.ssllabs.com/ssltest/analyze....extpvr.com

Yeah, as I mentioned above, tls 1.0 and tls 1.1 are disabled. Only tls 1.2 is enabled.

As mentioned, the issue is now fixed. Just run the updated installer.
