Qualified certificate verification path problems

[Sfor]

I've been told by the support stuff member, their qualified certificates will not work on Windows 98, because of some fault in the system verification procedures. On the other hand qualified certificates from a different authority are working correctly.

I've tested the same certificate is not verified correctly on Windows 98, while everything works fine on Windows 2000.

I would like to know, what differences in the certificate verification systems are in Windows 98 and 2000? And possibly, if there is some way to make Windows 98 certificate verification services to work the same way as in Windows 2000.

I have found some informations the problem is related to UTF8 coding problems in Windows 98.
