Assuming you are upgrading from a 32 bit xp/vista install to a 64 bit win 7 install the problem is not the write protection, it's just a bad error message. The 64 bit installer cannot run in a 32 bit os - you must burn the iso and install as per all the messages in this thread.
If you really want to remove the read only bit (it won't help) feel free to go to your command prompt and use attrib -r c:\INSERTYOURDIRHERE /d /s
The read only will be cleared but you will get the same error message.
Agree with prior poster here, it can be accomplished within the installer by selecting advanced options at the screen where you are prompted to select the hard drive to install to.
Disagree with prior poster here although obviously his experience should give some cause for concern. I have upgraded both a win 32 and a vista 32 machine to win 7 64 and in both instances I've formatted the drive from within the installer. In both instances my upgrade key worked fine - I'm still finding it hard to believe that MS would be stupid enough to not allow this to work.
I'm not sure what the process looks like when running the installer from Windows but it wouldn't be able to format the drive the installation files are on and at the same time complete the install. Might be possible to format a separate drive and do the install from within windows.
No.
I would use clean install to mean that you formatted the drive but in this case there is actually some cause for confusion. When the win 7 installer starts two options are presented, (1) Upgrade; (2) Custom Install.
As I understand it the upgrade option will allow you to maintain files and settings but is only available when (1) you are going from Vista SP1/SP2 to Windows 7 AND (2) you are upgrading to the same bit operating system (e.g. 64 bit Vista -> 64 bit Win 7).
All other users must choose custom install. If you choose custom install AND you don't format, Win 7 will backup some of your files to a windows.old folder - your progs will not be usable though. If you choose custom install AND you do format then Win 7 will not backup any of your files.
Note that if you're running XP and you want to migrate your files and settings MS has some easy transfer tool - I've never tried it as it seemed like more effort then it was worth so I don't know how it works.
Same as above really - if you're selecting the upgrade option or not formatting you're arguably doing a "not-clean" install. Note though that in the custom install / no formatting scenario you're still really getting a "clean" os install as win 7 isn't using/upgrading any of your old os files (it's just backing some files up to a windows.old directory).
