The Windows 8 upgrade failled every time due to a hardware issue (the PC went back to ACER for a board and memory replacement).
The Windows 7 package got corupted during the upgrade and the backup on the hidden partition also failed due to hardware mismatch digital signing error.
I had to format C and install the standard Windows 8 Home Premium from a genuine Windows DVD, then download and install all the acer drivers to get it working correctly.
I could not find any where to get the software back that was originally provided by Acer.
I ran the Windows 8 Upgrade with the Acer assistant and it all went pretty smooth with a few driver updates.
Only thing now is the Acer remote control only works the volume, cursor, the power buton and the I dont know where to get the additional software back.
Non of the backups (hidden partition or the 4 DVDs I burnt) work on the PC since the repair done at ACER.
