Java SE (Java Platform, Standard Edition)

When installing Java 1.4.0_01 under Windows 98 through the self-extracting executable (both the international and non-international runtime environments, and the SDK) I get the following error message (soon after the splash screen appears; right after files are checked and unpacked):

'An installation support file could not be installed. Interfaz no registrada [Non registered interface?]'

Following the installation guide I went to InstalShield's support page and checklisted through article Q104985 without success (only thing I couldn't do was execute DCOMCNFG because of some issue regarding user level security but I don't expect the problem to lie there). JRE version 1.3.1_03 installs correctly, so I am not in a great hurry, since I don't expect to run state of the art programs in the Pentium 166 I am setting up, but it would be a relief if anyone could enlighten me about potential ways of solving the issue. Thank you.
