register error

[Andre W B Furtado]

While trying to install GHC-5.02.3 (win32 release) in my computer (Windows
98), I got the following error message:

Error 1406: Could not write value _MainFeature to key
HKEY_LOCAL_MACHINES\Software\Microsoft\Windows\CurrentVersion\Installer\Feat
ures\8C655693FA0801D4E87FA1CA60C4AAE1
Verify that you have sufficient access to that key, or contact your support
personel.

I then finished the installation, and would like to ask 2 things:

1. What problems am I supposed to expect with this error?
2. Why this happened? I though I had sufficient access to all needed
register keys... :)

Thanks,
-- Andre
