SQL 2008 R2 repair error

Hi all,

I am trying to run a repair on my SQL installation and am receiving the following error...

"File C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Binn\DllTmp64\sqlagentctr100.dll could not be copied to file path C:\Windows\system32\perf-MSSQL10_50.MSSQLSERVER-sqlagtctr.dll"

When I check the summary log file I have the following...

This is a new cluster install of 2008 R2 on W2K8 R2 boxes. I removed the passive cluster node prior to this repair though as a previous repair told me the install on that node was not successful.
I am thinking it may be as easy to start again with SQL but if someone could offer me a fix that would be great.

Thanks
