Do you have XP installed as NTFS? How large is your My Documents folder? It's possible there is no more room to work. Does the installer show where it is going to extract to? If so, you might be able to create a folder such as C:\canonscan and point it there.
OS Win XP Pro.
I downloaded driver from canon a few times.
When trying to install get error message from
WINSFX32V22.214.171.124 (which is selfextractor I believe)
then location C:/ Documents and setting/my name/my documents/SGCS7133WNEN"Write error.
SGCS7133WNRN is the driver I downloaded.
Any wiz can help.
