Windows 7: I tunes

Just tried to install Itunes 10.1 but get the window i nattacment,also cannot uninstall 100% as Bonjer is still running have treid most reccomended solutions including a different user profile
Also now cannot install windos update Error code 57 A
Would appreciate any ideas

Welcome
Did you try these?
Try to uninstall in safe mode
Go to run (by search)
type msconfig
go to start up items
Then uncheck the program that is the problem, then reboot.

Many thanks did all you reccomended still get unknown file that will not allow installation

Just to be safe
Make a full antivirus scan
Download and make a full updated scan with malwarebytes

I am sure that this is ok, but just that small chance. Lets play it safe

If you are negative, we can try with revno to uninstall.

Ok willdo thank you

Just finished no infections found!

Does bonjer have to do with your printer?
On a network?

Sorry it is part of I Tunes I managed to delete it in safe mode
Should be BONJOUR

OK so its all deleted and yet you cant uninstall because it is supposedly running?
If so download and use ccleaner. It may be remnants that remain.
Piriform - Download CCleaner, Defraggler, Recuva, Speccy - Millions of users worldwide!

I use CC Cleaner as a standard no luck
as I had tried to reinstall I went into safe mode and tried to uninstall Bonjour it came up with installer not working, possibly the windows installer is the problem
I do not which one to down load from microsoft for windows 7
Am off to bed thanks for help so far will try again tomorrow
The joy of being retired
