Siebel

Hello all,

do you think it is possible to successfully install the 32-bit Siebel Web Client (version 7.7 and 7.8) on Windows Vista 64-bit ?

I'm running Siebel client software against an Oracle 9i database. In fact, my Oracle client is version 10g (32-bit). But it works fine. Even with non-Oracle software.

I succeeded in installing the 32-bit Siebel Tools (7.7/7.8) on my 64-bit Vista. Just had to prevent the installer from putting the software into the default folder which is "C:\Program Files (x86)". Using the default folder resulted in the Tools being not able to locate the Oracle tnsnames.ora file. I created my own C:\PRG folder instead. So for example, I now have "C:\PRG\Siebel\7.7\Tools" for Siebel Tools 7.7.

I hoped this method would work for Siebel Web/Developer client 7.7/7.8 as well. But it didn't. In the middle of the installation process, the installer told me it could not locate MDAC and rolled the whole thing back.

I googled a bit around and found that Windows Vista do not use MDAC any more. It uses "Windows Data Access Components" (Windows DAC) instead. But I also checked my "C:\Program Files" and "C:\Program Files (x86)" folders and found that, for example, msado15.dll and msadoXY.tlb (which is a part of that MDAC/DAC stuff) is there, both 32-bit and 64-bit versions.

So my question is:
How can you make the Siebel Web Client installer think that MDAC is in place and find it there (in the 32-bit folder, of course)?

I'll welcome any help.

Thanks,
Pavel Foltyn
