Activate AM v62A (Norming's Asset Accounting) Error

Hi,

We have a customer that recently buy AM. We just install and when trying to activate in a testing company (to setup AM master files, importing fix assets opening balances and so on) we get these errors :

We just did common tasks to fix this : uninstall/install with administrator rights, force to run as administrator when running a) AM unreg.bat and reg.bat or b) runtime/regacc.exe and so on...no luck same issue. Customer has Sage 300 ERP 2012. Any idea?
