Rio F2084 Internal Error

FMX TMS FMX UI Pack
1
Just upgraded to Rio and the latest  FmxCloud and FmxUiPack.  Finally got the packages installed.  Tried building a project that built fine in Tokyo.

[dcc32 Fatal Error] TMSFMXCloudPackPkgDXE11.dpk(29): F2084 Internal Error: AV10874370(10730000)-R4D7A8707-0
[dcc32 Fatal Error] TMSFMXCloudPackPkgDEDXE11.dpk(29): F2084 Internal Error: AV10874370(10730000)-R4D7A86E0-0

[dcc32 Fatal Error] TMSFMXCloudPackPkgDXE11.dpk(29): F2084 Internal Error: AV10874370(10730000)-R4D7A8707-0

The offending line in each case is {$IMPLICITBUILD OFF}
A search for F2084 suggested setting Use MSBuild externally to compile to true.  I did that but still get the same error.
Thanks for any enlightenment anyone can offer

We have already updated the packages for Rio, please use the automated installer (download the latest available version) to install both TMS FMX Cloud Pack and TMS FMX UI Pack. manual installation is not recommended.

I used the automated installation of cloud 3.4.0.0 and UiPack 3.7.0.0 after editing RSVARS.BAT

Does your project have dependencies to TMSFMXCloudPackPkgDXE11?
If so, please replace this to: TMSFMXCloudPackPkgDXE12. In Rio, the packages installed have the DXE12 suffix.

For now, I'm reinstalling Tokyo.  I've had other issues with Rio, and don't have time to fix them all now.
