Hi, The HDD failed on my Maplin Sentient 4 Channel Network DVR. I swapped the disk for a new one and re-formatted it. All seems OK except I am now unable to view video from Internet Explorer? If I click on the link on the DVRs homepage to download the plugin I get 'inst4twn.exe File Not Found' - this seems to be attempting to download from the DVR itself? Does anyone know if this is supposed to be on the HDD or on the Software CD that came with the DVR (which I have unfortunately lost)? Thanks for any Help.

I purchased an (original) Software CD for the DVR from an ebayer who was selling these units. Everything working fine now!

Erm what problem??? The ONLY problem I currently have is that I can't find a trustworthy version of the Inst4TWN.exe installer. I haven't EVER actually installed it on any of my PCs (except inside a virtual machine - which I subsequently erased).

Hi - This DVR is a little different from the usual devices that use activeX in that it makes no attempt to do an auto-install on loading the webpage. There is merely a link on the homepage that allows the download of an installer called Inst4TWN.exe. If this installer is run it installs a standalone DVR viewer application AND the activeX control (VxCtrl.ocx). I have tried installing just the activeX control (using regsvr32 VxCtrl.ocx) - within a Windows Virtual Machine and it seems to work fine. The problem I have is there seem to be many warnings about Malware versions of the Inst4TWN.exe installer and I no longer have the original CD that came with the DVR. I downloaded the version I tested from a website called DF SECURITY (df.dyndns.tv) but I have no idea whether this is a 'safe' copy.

Ok as an experiment I copied my suspect copy of Inst4TWN.exe onto a USB pen drive and plugged it into the DVR. Following the procedure in the Manual I Successfully uploaded the file onto the DVR (the DVR recognises the file as version 2.68 with a checksum of 0x05A6F9F5). From I.E. on my PC,browsing to the DVR homepage, I can now select 'Please install this file, if you can`t see a black box below.' and the file downloads ok. Obviously there is no way I'm going to actually run this dodgy file. This would seem to indicate that there is NO PROBLEM with my DVR - I just need to get my hands on a trustworthy version of the software CD. (I'm currently in negotiations with an ebayer who is selling one of these DVRs to see if I can get a copy of the CD from them...)

Quote from DVR Manual:- “Upload IE ActiveX File”: Upload Active-X component to DVR for PC (IE Browser) using. To get Active-X component from CD as attached and save it into USB disk. Then plug the USB disk into DVR for installation. So Wherever it is stored - whether in Flash or on the HDD there is an option to upload it to the DVR - If I still had the Software cd...

I agree - I have tried downloading Inst4TWN.exe from some random (and possibly suspect) site using a 'One time use / disposable Virtual Machine' The plugin seems to work fine - but I wouldn't risk running this in any non-captive environment.

The ActiveX plugin is uploaded to the DVR (and stored on its disk) purely so that it can be offered as a download (to a Windows machine - running I.E.) from the DVRs webpage.

what you may have done with the reset is removed your dvrs local ip settings you may have to manal input them again I can ping and browse to the DVR (using I.E), however the part of the webpage that should be the CCTV image remains blank.

I only ever used it before locally so never bothered to try the ActiveX control (silly I know - oh for a bit of hindsight!).

Managed to download a copy of the manual from the Maplin website - apparently on replacing the HDD I need to upload the Inst4TWN.exe file back onto the DVR from the Software CD (which I've lost). Looks like I need to find someone who has the cd.
