after formatting my window XP SP2, when i want to install my motherboard driver, a massage poped up "D:\ is not a valid 32 application". my motherboard is MSI865PE NEO2, my prosser is P4 2.66G with 2 pieces of 512MB kingston DDR RAM. PLEASE help.How are you trying to install these drivers and where are they from ? ?After installing OS, I inserted the Motherboard CD-Rom which came with the product. It did not auto-run and the message popped up. This has never happened before. Then I went to the MSI website to download the bios live update program. When I ran the PROGRAMME, a message "this program is not a valid 32 application" popped up again. Please help, thanks!I'm at my other machine right now and don't have my MSI MBoard CD here...
I'll get back to you as soon as i can.
Is there a setup.exe on the CD ? ?

I would hold off on running the Live Update for now as 1) you may not need it and 2) it has had some issues lately...Hi, this is the message i got when i inserted the CD to see if there is a setup.exe on the CD:
"vsmon.exe- Application error
The instruction at "0x7c901010" referenced memory at "0x0176f60c". The memory could not be "read". Click on OK to terminate the program"

thanks!OK this is starting to sound like more of a Windows issue here...
Is your XP SP2 CD legit ? ?
Is EVERYTHING else running properly ? ?

I just called a Customer who i did a build for with the same MBoard. He looked at the CD and provided the info i needed.
You should be able to open Windows Explorer and navigate to the CD.
There will be a setup.exe LISTED at the bottom...just double clik it and the CD will load.
There will be a driver button on the screen ALONG with MSI Ifo; Browse the CD; Options etc.....click on the Driver button and it should run the setup process for the MBoard drivers.
If this procedure does not work for you i'm afraid there is a problem with your XP install...

Let us know...

P.S. You may want to check the MBoard manual...if i remember correctly that board takes DDR2 RAM and you may have the wrong RAM installed.I have been busy these few days and is not free to visit this forum. My windows is legit and one of my sata HD is not functioning in this motherboard and I had tried all of the comments, and it did not work. So i have changed the motherboard and it is working now. Thanks for all your help.Good to hear you got it working...so both SATA drives are up and running now ? ?Hi there, yup they are finally working now! thanks loads for all your help!You're more than Welcome...stop by anytime !
