SP2 Install Problem

[Mike]

Hi,

I'm trying to install XP SP2, but it always has 2 errors when backing up the
registry. I found a KB Article (873148) which covers this problem, but I
can not edit the permissions on 2 of the Registry keys;

HKCR\.msi and HKCR\.msp

Both those are, of course, Windows Installer keys. When I go to open either
1 I get "Access is Denied". When I go to Permissions for those 2, it says
"Unable to view current permisions, but you may change them".
Well, I make the changes to the permisions, but it absolutely will not save
the changes... I still get access is denied.

I have installed the latest Windows Installer 3.1 v2, but it still has not
changed this problem. I am using an account with Computer Administrator
priviledges.

Any help would be greatly appreciated.

Mike

Hi Andrew,

I have already tried to adjust as required in Safe Mode, but same result.
Those 2 reg keys refuse to have their permissions modified by conventional
means. I am a technician and pretty darn good at fixing XP problems, but I
don't know everything, and this one has me stumped.

Thanks for your time,

Mike
