Error 39: Cannot install custom bt848 64-bit driver in 8.1

Hello!

I posted this in www.sevenforums.com and they just ignored it because I mentioned Windows 8. So I repeat it here in the hope that I'll have some help. Thank you in advance.

Sorry for starting a NEW topic, but after a quick search I couldn't find something similar. I will describe you my problem, so you can understand what is going on. Previous summer I upgraded my computer to a more up to date with 8GB RAM. Inevitably, I had to backup my data and install 64-bit version of Windows 7. I could install and use most of my devices, except an old Pinnacle Studio Pro analogue TV tuner PCI card. After some search, I managed to find custom 64-bit drivers fot BT848/BT878 cards and instructions of how to sign them, so I could use them in normal mode. After following the instructions the drivers worked fine in Windows 7 Ultimate 64-bit! OK, the original application Pinnacle Vision didn't work since it looks exclusively for Pinnacle's own 32-bit driver, but I could use the card in Nero Vision, Pinnacle Studio Pro, VirtualDub etc.

How did the problem arised: I recently upgraded the computer to Windows 8 and then to 8.1 so I have the latest version. Some devices were replaced with Microsoft drivers and others were not installed. I downloaded latest OEM drivers and managed to make all devices work at their full potential again, except the Pinnacle TV tuner. I went to advanced startup options and loaded Windows 8.1 in the mode that ignores driver signature. I then attempted to manually install the custom BT848 64-bit drivers from Device Manager, since there was no setup program. As you may know, the card appears as two devices in Device Manager. One for the video part and one for the audio part. The audio part completed sucessfully. But the video part displayed the message "Error 39: file not found". The same driver worked OK in Windows 7, so the missing files should be Windows 7 system files that are not present in Windows 8. Is there any way to see which files are these so I can copy them from a Windows 7 installation? How I can determine which file was not found when I see error 39? Is there a log file or what?

Thank you again

Well this isn't a windows problem, that why you got no response in the Seven forum. You'll need to find a support forum for "Pinnacle
products" perhaps they have written a win 8.1 driver or other users have found a work around. Not all programs are compatible with win 8.1.

Hello!

You probably didn't understand my question. I didn't ask you to find me the driver, I have it already, there is nothing more to download, believe me, I have searched for hours. And, unfortunately, Pinnacle considers this product dead and hasn't even Vista drivers. In 32-bit version of Windows I simply use the XP drivers in compatibility mode. But what about 64-bit version? There is no official 64-bit driver, not even for Windows x64 Professional, otherwise, I could obviously use it. So all I can do is use the custom 64-bit drivers for all BT848/BT878 based TV tuners. God bless the guy(s) that developed it!

To make my question simple enough: Is there a log file when installing drivers? How can I determine which specific files were not found when I see "error 39: file not found". If I know exactly which ones are the files that are missing, I can take them from a Windows 7 64-bit installation and I will then succeed in installing the driver in Windows 8.1 Since the very same driver worked unmodified in Windows 7 64-bit, common sense says the missing files are Windows 7 system files that are not present (at least not at the same folders) in Windows 8.1. I remember older versions of Windows (XP and older) allowed the user to browse for the missing files. I have done many successful installations in such cases. But Vista and newer are too automatic that they simply fail without telling you which file wasn't found and of course without the option to browse for it! Is there any way to change this behavior?

So for a last time: How can I determine which files are copied when installing a driver? Is there a log file or some other way?

Thank you in advance. I cannot be clearer than that.
