with about 7 mins left i get a message saying "INSTALL FAILED. The Installer could not validate the contents of the 'JavaTools' package. Contact the software manufacturer for assistance" i can not figure out what it means anyone have an idea

anyone?

It's strange ... Sounds like an issue while burning the ISO.

i have used 2 different burners and two types of blank dvds multiple times at different speeds
what should i do?

Did you check the md5sum of your ISO ?

Hey zeph do you know of an issue of the install stopping with about a min to go in 10.5.2 with like a half a inch everything stops except the mouse and then I have to do a cold shut down but when I reboot leopard still loads, should I go back into the install?

Yes you should.

Did you check the install log ?
Because at the end of the installation process, the installation does a "diskutil repairPermissions" and system seems stuck at one minute left.

Ok thanks when I go back into the install should I change it back to what i customized the install to or go straight through without changing anything?

Don't select anything but don't forget to deselect all unneeded languages !

how do i check the MD5 sum??

funny because same thing I thought happened to me until I moved my mouse cursor and the progress bar changed. it was stuck when it said 12mins remaining. When I moved the mouse 11mins after it said 1min remaining. The progress bar shifted from 12mins to 1 min. I once didn't do anything and restarted on its own and the install was flawless. Is this a DVD problem. Or can this be a normal thing? Appreciate help, thank you.

ok well i checked the md5 and it is exactly the same as what was posted and i get the same message still every time!

ok the only think i could think of was to load the iso and remove the package that has been giving me problems, besides its only java i can install that later on anyways. i will try again with this altered dvd

well that didnt work i need to adjust the install script

Hi!
I have the same problem. Once it was the same mistake, in other cases there were errors in package "essentials".

Here is photo of error and installer's log :
http://picasaweb.google.ru/ilushin.alexandr/MacOSInstall
Hardware configuration:
AMD Athlon 64 s939 3500+ (venice - SSE3)
Asus A8V-E SE (VIA K8T890 + VIA VT8237R)
Memory 2x512Mb
Video NVIDIA 7300GT PCI-e
HDD Maxtor IDE 20Gb master (first chanel)
HDD Seagate SATA 250Gb
DVD IDE BENQ DW1640 master (second chanel)
Mouse and keyboard PS/2 (mouse and keyboard are working in the installer)

md5sum is correct, I burned two DVD with some different programs on different speeds (4x and 8x), both of them work identical.
loading work correctly from DVD, after that I make partitions (I try to install both HDD, format and make partitions in Disk Util ,try MBR and GUID), after that I choose, what can I install ( I tried in different ways, including I deleted all che?k boxes), and, when the installing begins, after 16 minutes, the installer writes an error:
"Install Failed
Mac OS X could not be installed on your computer
The installer could not validate the contents of the "Essentials" package. Contact the software manufacturer for assistance."
What can I do in this situation?

you have a bad disk, try and burn it again at a slower speed and/or with a different program.

If this for me:

you need to try burning at 2x or even 1x, or else your likely to end up with a corrupt disk. Sorry to tell you...

I burned the DVD at 16x without any problems ... Very strange that people who tried to burn it at slow speed managed to fix their problem.

What could you say about log on the photo?

I think it depends alot on the program you use to burn it, i burned a coaster of the original release with toast. I burned another working copy with diskutility. Go figure.

K3B on Linux.

According to what I see on the photo it seems that your copy is not good ... but you're not the only one who experiences this issue.

Tomorrow, I will try another DVD drive (SATA) and I tell you about result.

ok

the funny thing about this is that i even tried a copy of 10.5.1 that injected a via sata kext to (finnaly learned how) and i ended up with the same result, though i had previously installed it on an IDE drive fine (just ran slow as hell)

anyone think thats the reason?

anyone?

maybe i should install windows on my extra ide hd and use vmware to install leo, since thats always how i had to install it for tiger

there is another option if you have plenty of disk space and no DVD's. Write the ISO to another partition, flag it bootable and boot the install from it.

Hi!
I install another DVD drive (SATA Lite-On) and, after that, system installation was successfull. I used the DVD disk, which I recorded earlier on BENQ DW1640.
I noticed that on BENQ DW1640 drive the speed of reading was maximum, but on the Lite-On drive DVD disk was reading with minimum speed. May be this is the reason of errors? How can I improve it?
