I have problem with installing java i have this error: Windows has found problem with this file. "name: jre1.6.0_27-c-l.msi "
publisher unknown publisher. this file was blocked because it doesn't have a valid digital signature that verifies its publisher.
Re download the file, run as admin. if that doesnt work, try checking date and time settings, and ensure windows isnt somehow blocking the .exe from checking its signature.
In addition, make sure your downloading this file from the correct website and you have the correct version for your windows/cpu
eg, 32bit for x86 windows
