Unable to activate windows XP

I had to do a repair install of Windows XP when I changed the motherboard.
after the repair install I could not activate windows. I received this error at the start of the activation process.
The problem was caused because the repair install downgraded Internet Explorer to IE6 I had to download and install the IE7 program.
After IE7 was installed the Activation could occur.
