PWP7 does not run on Windows XP SP3

[Dieter Mayr]

In my old Laptop works a Intel P III mobile without support for SSE2.
So I guess we can tell that it is evident that PWP7 in it's current version needs a processor that supports SSE2.

Thank you very much, Dieter!
So, SSE2 support is really required. :(
But that brings us round to MS VC++ 2012 again, because, if I'm not mistaken, it's the 1st MS VS that enables SSE2 by default. I did research a little about it, because I remebered the nvidia case, a relevant precedent regarding SSE2.
One solution, in case the developers would be so kind as to rebuild the sources for non-SSE2 processors, would be to fall back to MS VS 2008... But that's not the only solution, because rebuilding with /arch:SSE and /Oi- (just to stay on the safe side), should be enough to produce a non-SSE2 dependant build, to cater for the users who have older processors (Please!).
@moderator: please, if possible, do correct title to "PWP7 does not run on non-SSE2 CPUs", now that we found out what the issue I found really amounts to.

Thank you all for tracking this down. We have to test out the hypotheses above and make sure there are no other surprises and then see what the best course is.

Well, Kiril, I've got just one more piece of info I gathered after my previous post to offer: starting from those Dependency Walker traces I attached to a previous post and then looking at the executable using the built -in disassembler from PE Explorer, I found the following:

From PWP_7.0.09_DW.txt
00:00:01.906: First chance exception 0xC000001D (Illegal Instruction) occurred in "PW70.EXE" at address 0x0071B32C by thread 1.
00:00:01.906: Second chance exception 0xC000001D (Illegal Instruction) occurred in "PW70.EXE" at address 0x0071B32C by thread 1.
00:00:01.906: Thread 2 exited with code -1073741795 (0xC000001D).
00:00:01.906: Exited "PW70.EXE" (process 0xAD0) with code -1073741795 (0xC000001D) by thread 1.

Then using PE Explorer:
0071B32C F20F100558B77F00 movsd xmm0,[L007FB758] ; SSE2
0071B334 F20F11054016A300 movsd [L00A31640],xmm0 ; SSE2

Once again, thank you very much.

Can I still keep believing a non-SSE2 build is on the works?
It's just a matter of rebuilding the sources with some added command-line parameters, after all... at least in principle.
There still are lots of people using daily non-SSE2 machines as their only computer...
Thanks in advance.
Cheers!

I will try to build a non-SSE2 build for testing after I complete some other work doing. When I do, I will send it to you to try. However please note that I have no idea if that will be successful or not and there is no commitment to release such a build at this point.

This post is just to say the issue I found has been solved with PWP 7.0.11 (the relevant part of its release notice is quoted below).

The Picture Window Pro 7.0.11update is now available.

The 32 bit version is now built so that it no longer requires the SSE2 instruction set. (SSE2 was introduced about 10 years ago as a Pentium enhancement.)
This makes PWP compatible with older systems that do not implement these instructions.

For full details of the changes see http://www.dl-c.com/update70.html

The new software can be downloaded here: http://dl-c.com/content/view/23/54/

This post is also to thank Kiril for the great support and both Dieter and Kiril for the kind attention and all the help offered. You both do rock!

Hi, All,

I just installed PW Pro 7.11 on my XP Pro SP3 OS. The machine has a Pentium 4 running at 2.8 GHz There is 2gb RAM.

Everything runs fine!

I use a Sigma DP2 camera that produces 12 plus MB foveon raw (X3F) files that I process with Sigma Photo Pro to produce tiff files of 27-28 MB which I then develop in PW Pro. No problems, no lockups, etc. (Of course, now that I have said that...)

Julian,

Yes, it's amazing what few recommendations PWP has on the hardware.
During testing in this case I instzalled it on my old laptop, a 1 GHz PIII with 500 MB RAM.
Ver. 7.0.11 runs even on this, and it's able to work on JPEGs from my point and shoot (about 4 MB each).
I did'nt test RAW processing, but with patience it should be possible too.
Of course, complex operations like Advanced Sharpen are no pleasure to use on such a old machine.
But that laptop is not intendet for such things anymore, I have it in my kitchen for my recipe database and Internetradio.
