I'm tring to install the Microsoft Certificate Services CA Chain on a Win98 machine but when I try to install it, the 98 machine say's: This is an invalid PKCS #7 Certificate file. The Chain installs fine on all my other, XP, machines but not the 98. My Certificate Services site is here: http://cert.djxmmx.net/certsrv/cert... I know Win98 is a dead OS. I was doing some fooling around in it for fun. No problem if this cannot be resolved, just wanted to know if there is a workaround.

I already tried google'ing for the answer. I always try to find an answer myself before posting on any forum. That is not helpful. Any one else?

I found a work-around: Download the Certificate Chain, directly, from the Certificate Authority (http://xxx.com/CertEnroll/xxx.crt) A download prompt will come up, just click "Open" A dialogue box should come up containg information about the certificate, click "Install Certificate". A wizard will now start and guide you through the certificate install process. Leave all the settings at their default values, click "Next" twice, and then "Finish". The big problem was the default Microsoft Certificate Authority certificate install ASP page was built to convert the certificate to different forms or use an ActiveX controll to install it, which I guess, is not compatiable with Windows 98. A simple direct download, will allow you to install the certificate on older systems.
