BPC 10: Need to restart admin in order to start Excel.

Hi,

A weird problem in SAP BPC 10..

When I start the Admin (internet explorer 9) I launch the "EPM office add-in for excel". It starts up excel and works fine. But if I close Excel (all running excels), and then AGAIN try to launch the "EPM office add-in for excel" from the admin module - nothing happens..

I have to shut down the Admin module and restart in order to launch the EPM office add-in for excel again.

Any ideas or anyone with simular problems ?

Regards
