I found a solution to the problem but not a good one.
It turns out that the Inventor 2013 iLogic AddIn is trying to reference a type library found in Inventor 2011. It should be located in C:\Program Files\Autodesk\Inventor 2011\Bin\InventorVault.dll. If you don't have Inventor 2011 installed then the iLogic AddIn will throw this error.
On my target PC I just had Inventor/Vault 2013 installed and kept getting those errors. As a test I installed Inventor 2011. When I ran my custom AddIn that I'm developing for Inventor 2013, the iLogic error message went away.
Since the iLogic AddIn references the IVaultApplication interface from 2011 and is not provided in 2013, will Autodesk provide this DLL future distributions or service packs of Inventor?
More Detail...
The application I am working on is a custom AddIn for Inventor. It started out as an AddIn for Inventor 2011 and so I needed to update it to work with Inventor 2013. All was fine on my development PC but when I installed my AddIn on a new PC I would get the "Error in rule: Parameters" popup. The error message appears right about the time RunRules is called. Strange thing is that the message box complained about a missing VaultAddInLib.IVaultApplication interface. It didn't make sense to us what this error message was telling us. Drove us crazy because we thought the problem was coming from our iLogic code which didn't have anything to do with Vault.
System.InvalidOperationException: Failed to create VaultAccess object. ---> System.InvalidCastException: Unable to cast COM object of type 'System.__ComObject' to interface type 'VaultAddInLib.IVaultApplication'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{6796EC03-5DAB-4B0B-849B-41195C3429E8}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

On my development PC I have both 2013 Inventor/Vault Professional and 2011 Inventor/Vault Professional installed. The iLogic ran fine with no error messages.
On the PC I was targeting I installed 2013 Inventor/Vault Professional with all of the required service packs. The 2011 Inventor/Vault was not installed. On this machine my application displayed the above error message.
On my development pc, I searched for the registry for IVaultApplication which appeared in the above message. I was able to find it. On the other PC I was not able find anything in the registry concerning IVaultApplication.
I searched my development PC for the InventorVault.dll and there were a couple listed for Inventor 2011, 2013, ETO, and iLogic so I didn't know which was the reference. I used oleviewer.exe to examine the IVaultApplication interface and found that its referring to the VaultAddIn 1.0 Type library located in C:\Program Files\Autodesk\Inventor 2011\Bin\InventorVault.dll. It has the same class id referenced in the error message.
I installed 2011 Inventor and now the error message does not appear.
