COM Exception in Application

I'm trying to upgrade an internal application, the infrastructure will be moving from 2008 to windows server 2012. The application builds presentations from model templates.

I keep getting the attached COM Exception which looks to be associated with Interops, has anyone come across something similar.

PowerPages (Office 14.0)

Document: Model.ppt

Command: {SET PrevPeriodEnd user.PreviousPeriodEnd(PGFromDate)}

Error:

~~ Call Stack Pages 6.9.1 (Build 021)~~

Member not found. (Exception from HRESULT: 0x80020003 (DISP_E_MEMBERNOTFOUND))

Two (obvious) possibilities:

Is word installed? Looks like whatever is calling powerpoint is also calling word.

Is your app running as a 32 bit app? 2008 can be run as a 32 bit OS but 2012R2 is 64 bit and you may need to mark everything as 32 bit. (I think you can use CorFlag.exe to force this)
