IWServerSession was compiled with a different version...

I've just upgraded from Standard to Ultimate to gain access to the source code to aid in debugging. I have downloaded the latest version (iw15.6.7.exe) and the latest sources (IWSource15.6.7_20240916.zip). I have added the relevant paths to the Library.

When trying to compile it returns the error:

IWServerSession was compiled with a different version of IWIpAccessTable.TIWIpAccessTable

I note that there is no source for IWServerSession but there is for IWIpAccessTable.

Should the source for IWServerSession be included in the Ultimate edition? If not, how do I get around this issue?

Thanks
