Unknown product guids - The license state for the current server doesn't match the farm's license state

I'm trying to add a 2nd server to our SharePoint 2013 RTM farm, and getting the error "The license state for the current server doesn't match the farm's license state". From what I gather (from here msdn blog) it is probably 2 missing products that are installed on the 1st server which is already part of the farm.

Looking in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\15.0\WSS\InstalledProducts, The two guids of products that are missing from the 2nd server are:

52D457F6-AE45-4221-9BC5-1912A8861C00

CCD2BE5B-DCB6-4FBE-8087-3E5C82244473

What products are these two guids related to? I can't figure it out for the life of me.

I did a search via regedit to find any other occurance of those 2 guids which might clue me in to what they refer to, but I could not find anything. (the guids in the registry match the sharepoint config database using the sql in the link above, so that is fine too)

The 2nd is something that starts with "Microsoft Foundation" but I'm not sure what it is since I can't find any information on either guid at http://msdn.microsoft.com/en-us/library/jj659075.aspx#bk_SP15DetectSKUaddresources or in a general google search.

I have run the prerequisite installer but it just tells me everything is already installed.

Both servers have Foundation and Enterprise :

B7D84C2B-0754-49E4-B7BE-7EE321DCE0A9

9FF54EBC-8C12-47D7-854F-3865D4BE8118

The only thing I can think of is, the current (only) server in the farm used to have SP2013 Preview, but the guids don't match, and I had more SQL2013 products on it at one point which were uninstalled. But the guids don't seem to match those either.
Either that or something went wrong with the Prereq installer, and 2 products were not fully installed.

If I can figure out which ones they are I can re-install them. But until I know what those guids refer to, I can't do anything about it (beyond re-installing everything)

edit- I also tried running Set-SPFarmConfig –InstalledProductsRefresh  but it did nothing

thanks
