Hi

Am using Win 7 64bit

Trying to install windows live messanger..

But I keep getting this odd error

Could not open key:
UNKNOWN\componets\A49B681220C2EA49826
Verify that you have sufficent access to that key.
Contact your suport staff.

Please close other programs and then try again
It looks like another program is preventing the installer from working

eeror code Hr:0x80070643..

I looked at that error code

and I used this clean up tool thing to know joy... Reg scans done every thing I can think of.
I fix most windows issues but now after 2 hours am stumped what else to do. This is a clean install only 2 months maybe less

Only running id Eset smart security 4

Its oked in both that and windows firewall

Can any one help please i google this error and most of it talks about regesty cleaners and we all know they dont work done what it says on microsofts site

Funny how yahoo messenger works fine.

I only have anything made by microsoft even flight sim X

They dont seem to know their own OS and not good at helpful errors or ways to fix it.

Two things spring to mind, firstly try installing in safe mode, and secondly try disabling your AV during install, as sometimes the AV checking the files during install can prevent proper installation.

Thank you for your reply.

The pc was not letting me reinstall my AV software after the interface of it was blank lol.

So I backed up pc and did a clean install.

I think some how it was a virus blocking the registry some how.

Up and running now.

Safe mode did not work nor did turning AV off for a sec or to.. Maybe a virus got in then i dont no... I did a scan day before and was clean..

Ah well my pc is back

plus I did a disk check took 4 hours and found errors on the hdd why is that?

It means your hard drive might have some defect and needs look into,you might need a new drive.

Check your Ram as well.
