SYMPTOMS

When you try to install Internet Explorer 4.01 Service Pack 1, you may receive the following error message:
Internet Explorer 4.01 SP1 Active Setup You do not have enough disk space to install Internet Explorer 4.01 SP1 with the options you selected.

Internet Explorer 4.01 SP1 requires 33528 KB of disk space, but Setup will need an additional 12000 KB to complete installation.

You need to have 45528 KB free on Drive C.
This problem may occur even though your hard disk has 50 megabytes (MB) or more of free space.

CAUSE

The problem can occur due to the way the value for free space on your hard disk is calculated. Information about the amount of free space on your hard disk is stored in a dword value in the registry. If this amount exceeds 4 gigabytes (GB) of free disk space, the amount over 4 GB is moved into another dword value, and it is this new value that Setup examines to verify the amount of free space on your hard disk. For example, if this new dword value is 50 MB (because the amount over 4 GB is 50 MB), but Setup requires 100 MB, Setup incorrectly interprets the amount of free space on your hard disk to be 50 MB, and then generates the error message listed earlier in this article. Note that this problem can occur with large hard disks where the amount of free space on your hard disk is slightly above a multiple of 4 GB. For example, this problem can occur if you have 4.05 GB free, 8.05 GB free, 12.05 GB free, and so on.

RESOLUTION

To work around this problem, reduce the amount of free space on your hard disk to be slightly below a multiple of 4 GB, or increase the amount of free space on your hard disk to be at least 100 MB above a multiple of 4 GB.
