Windows 7 Pro
There must be an old version file ADVSTYLEIF.PAS still around on your system. Locate & delete this old version.
I found one instance of the file and deleted it. I found 4 instances of the DCU and deleted those. I emptied the recycle bin. I completely uninstalled and reinstalled the components.
Uninstalled the June 30 release and reverted to the previous release (June 15). Compilation errors no longer occurring.
With a clean install this issue should not happen. Perhaps there were leftover TMSDXE7.BPL / TMSDXE7.DCP files
I searched and deleted these files, and then installed the July 2 component package, version 7.9.0.1.
tsOffice2016White is declared in AdvStyleIF.pas, so the only reason I can see for the compiler not finding this value is that there is an old AdvStyleIF.* file around somewhere earlier in your library path than the latest version.
After reordering the library path, so that TMS Components precedes TMS Security, TMS Scripter, TMS Flexcel, TMS Diagram studio, the compilations now work.
