problems installing iatkos v7
 

Hey. I tried to install iatkos v7 today.

I get all the way until the install screen. It gets like 30% done, then says 'the installer could not validate the contents of the 10.5.7.intel package' what could this be?

Probably your download is corrupted at some part, try to check the MD5 of the iso (md5 = a code to check if the .iso file is downloaded correctly)

tool to check MD5:
http://www.midwavi.com/MD5.exe

MD5 of iAtkos_v7.iso: 6395be5253f53f716ed042db1dd599f3

crverik is right. But it can also be the media you are using. Use quality media and burn at the slowest speed to prevent any errors.
HOPE THIS HELPS
GOOD LUCK
