DVDFab 9 problems with Windows XP

[Eddie13]

Speaking of the free trial versions...

In my experience 9.0.6.3 was the last version which works OK with Windows XP. Although 9.0.7.2 installs without apparent errors, it will not run. Then the latest 9.1.0.5 causes an exception during the installation. Although it apparently installs the files OK into C:\Program Files, it will not run - causes same exception message (see graphic).

In comparison 9.1.0.5 installs and works OK on my Windows 7 computer.

So I'm wondering why the difference?

Could it be a new "unstated" .NET requirement started circa version 9.0.7.2...? I only have .NET 2.0 installed on my Windows XP machine.

Thanks for your help.

Microsoft will cease support on XP next April, probably most software vendors will too.

It's time to move on....

I read elsewhere that DVDFab plans to continue support for XP for awhile, at least, and believe they would like to fix this problem. Whatever clues we can provide might help...

[martythebrit]

Even so, XP is on it's last legs. Might be wise to do that upgrade....

One clue would be to run "dxdiag" click the display tab and post a screen shot.

Done...

That's the system tab, let's look at the "Display" tab.

[Eddie13]

Both graphics were/are there, long waits to get the server to respond...

All the DirectX features are disabled, see if you can get them enabled and it might make a difference.

Why do you say they're disabled?
They appear to be enabled to me!
Here's the Display tab after running the tests...

You're right I was looking at the wrong column. I guess the API to decode the graphics is not supported by DirectX9.0c or your graphics It's a problem I had with XP on a laptop. I installed Windows 7 and all is well.

[Eddie13]

Installing Windows 7 is not an option on this XP machine. I have a Windows 7 computer where DVDFab 9.1.0.5 works fine, but would like to get it working on the XP machine too...as would *many* other people, based on reading about this problem here and elsewhere!?

[90312]

Yeah I'm sure. Like Marty I'm afraid software developers will start to migrate away from XP because of its April end of life. It happened to Windows 2000 much to my dismay. If you are locked in to XP you'll just have to hold out as long as possible. You must have some necessary software that won't run under W7, I've never run across a system that wouldn't upgrade.

[Eddie13]

Do you think it might be a NVidia driver problem? I also tossed out the notion of .NET because I only have 2.0 installed. I don't have MS Silverlight on this XP machine either. Can anyone rule those out as causes?

For fairly certain, as reported by quite a few different XP users independently, DVDFab 9.0.6.3 was the last version to work OK. Later versions won't run or produce error messages.

So *something* must have been changed in the DVDFab code to cause it. What? Still a mystery...

[Eddie13]

Another possibility comes to mind... Later processors have more commands available. One possibility is SSE, which I believe describes my Windows XP processor command set. However I know that my Windows 7 computer processor will accept up to SSE4.2 commands. So if SSE4.2 commands were included in the coding of DVDFab versions after 9.0.6.3, they would probably not work on most older processors, such as are in most XP machines.

I updated my NVidia display driver to the latest recommended version (Feb 26 2013 driver 307.83) which didn't help, same exception when DVDFab 9.1.0.5 is installed on Windows XP SP3. It appeared to complete most of the installation but the exception happened before it could ask that computer be restarted. I restarted manually which didn't help, still won't run, same exception message. There is no associated log file.

I couldn't print a screen picture of the following exception info (wouldn't copy) so transcribed part of it below. It along with the attached 2b06_appcompatibility.txt file were to be sent to MS with the error report (not sent). I don't claim to understand it but maybe it will help your tech department troubleshooters.
