Problems Trying To Install SQL Server Express

I€™ve been having a hard time trying to install SQL Server 2005 Express edition. I€™ve never used SQL Server before, so I don€™t really know what I€™m doing.
During the System Configuration Check step, the Performance Monitor Counter Requirement errored-out, with the following message: The System Configuration Check for Performance Monitor Counter registry value has failed. For details, see How To: Increment the Counter Registry Key for Setup in SQL Server 2005. I searched the Microsoft website, and found this topic under ms143215, I don€™t know if this is the same as a Knowledge Base article.
This article tells me I have to manually set the increment for the counter registry key.
It says I need to use Regedit, which I€™m rather hesitant to do, knowing how much damage could be done with 1 wrong key-stroke.
Anyways, it tells me to navigate to this location:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionPerflib
€œLastCounter€? = 0x00002342 (9026)
€œLastHelp€? = 0x00002329 (9001)

The above are the values I found.

Then it tells me I have to navigate to this location:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionPerflib09

Then it tells me I need to replace the values in the above fields, with the corresponding fields from the above location. The problem is, the values in the above key are long strings of text, without any kind of search facility, there€™s no way I can find the 2 fields mentioned above.

I€™d truly appreciate any help!!
