DVDFab Platinum is without a doubt the best DVD backup solution on the market so not having this available on my Vista 64 system is a major pain. I would like to use this thread to capture information about DVDFab Platinum and Vista 64 with the goal of either finding a work-around or at least passing along whatever information is available to help the developers fix the Vista 64 problem(s).
I would like to skip the philosophical questions regarding Windows vs. Linux, Vista vs. XP and 32 bit vs. 64 bit that always seem to creep into threads like this and just focus on what is known about running DVDFab Platinum in Vista 64. I have looked into this for a while on my own system and it appears to me that the problem is likely to be a simple fix for the developers which is important to determine since Vista 64 probably isn’t widely enough adopted to justify a large, complex fix.
To start with, I have a question for Fengtao which is this; When you say DVDFab Platinum “supports Vista”, is it your intent to support both the 32 bit and 64 bit versions of Vista at this time? If you are not intending to support Vista 64 at this time, do you have a date estimate or a version number targeted for this support? Also, if you do not intend to support Vista 64 at this time, you should put an asterisk next to “Vista” on the product pages stating this so people don’t think that “Vista” in the supported systems section means Vista 64.
Ok, here is what I know about DVDFab Platinum on Vista 64.
First of all, DVDFab Decrypter runs perfectly on Vista 64. I have never had a problem with DVDFab Decrypter on V64 even back with pre-release versions. I have probably been using DVDFab Decrypter for almost a year.
The Patin-Couffin drivers appear to work fine on V64. I say “appear” because I can only use the simple menu-based functions to test them an don’t have any other product that uses them.
DVDFab Platinum has had the same exact crash problem on V64 going back at least 5 or 6 versions (whatever version was current when V64 was released). I have now tested it up through version 18.104.22.168 Beta. Here is what I know about the V64 Crash:
> When DVDFab Platinum is installed clean (all DVDFab files removed plus all DVDFab entries removed from the registry), it will install without error messages and conclude by asking for a reboot.
> When it is run after the reboot, it will start up and ask for the purchase verification key. When you enter the key, it will restart DVDFab Platinum which will crash immediately after the restart.
> DVDFab Platinum is setup to install when run as an administrator or not. It stores the keys for each permission context in a separate registry location. This means you can run the installation without checking the “Run as an administrator” option and go through the key request process where it will then crash everytime you attempt to run it. You can then run the installation again with the “Run as an administrator” box checked and it will ask for the key again. Unfortunately, it will crash in that mode just as with the first mode.
> Looking at a trace without benefit of source or symbols, it appears that it may be crashing in an integer math section which could be the key hashing logic. Perhaps there is some dependency on 32 bit integers. Only a developer with access to the souce code will be able to run a debug session on a Vista 64 system to find out for sure.
> I get the exact same crash results on an Intel Pentium D (950) desktop computer and two laptops that both have Intel Core 2 processors with Vista 64 on them. I have a Desktop that is identical except that it’s running XP SP2 and DVD Platinum runs fine there (of course ;-). These computers are all fully stacked with 2 to 4 gigs of RAM, 500+ gigs of hard drive space, etc. I use Plextor and NEC DVD writers. I have tried
Has anyone been able to get a version of DVDFab Platinum to run on a Vista 64 installation? If so, please describe your system (Intel vs. AMD, etc.)and anything you did to get DVDFab Platinum to run.
Does anyone have any additional information about DVDFab Platinum crashes on Vista 64? If so, please describe anything that might help others locate or reproduce the issues.
