EPM V10 issue : Install conflict between PCM 10 & BPC 10

Our team is working on a prototype of EPM 10 solution (BPC 10 & PCM 10). We have met 2 conflicts between BPC 10 and PCM 10 at client side (Excel & Internet Explorer):

1. There are 2 separate EPM Add-in for Microsoft Office (Excel). One for BPC and another for PCM. We should install EPM Add-in PCM at first, otherwise we can't install it after BPC. Obviously EPM Add-in for PCM is a previous version refering to that of BPC.

But after installation of EPM Add-in PCM then BPC, we lost the "Data Manager" tab in Excel ribbon.

2. After installation PCM 10, we canu2019t access BPC via Internet Explorer any more. IE shows u201CAdd-on can not work u2026u201D. But we can open BPC Web client via Chrome. Is there any conflict of the ActiveX between PCM & BPC for IE ?

Thank you for any proposition & solution.

Kind regards,
