Update SR3 after SR1a??

[HONYAKUKA]

Office 2000
WinXP

I have Office 2000 Standard (not an SR) on CD-ROM and installed on my PC.

I downloaded and installed Office 2000 SR1a successfully online.

I then downloaded SR3 and started the installation process. It first asked for
the Office 2000 CD-ROM, which I had. No problem.

It then asked for the Office 2000 SR1 CD-ROM, which I don't have. Thus, the
installation ultimately failed. Shouldn't the downloaded SR1a cover this?

(There is no opportunity to download SR1 as a separate entity from SR1a.)

So, do I need to order the Office 2000 SR1a CD-ROM?

Thanks.
