Upgrading ACS Models
Before upgrading a model used for code generation with ACS, ensure that no important data is held in the ACS cache (on client machines) by starting ACS and then clicking the Show Protected Properties button on the ACS/TDK Control tab. If this reports anything, you should reverse these into the model before upgrading.
If you upgrade from 7.1, note that some of the C++ code generators were renamed and merged so after upgrading you may receive an error like these:
"DLL not found Error"
'C:\Program Files\Artisan Software Tools\Artisan Real-time Studio\ItsShadow\Exe\Cpp Win32 Animation EXE.dll' does not exist or is not readable' error.
In these cases, you should choose the appropriate new generation scheme from the ACS Launcher instead, e.g. if you were using the Cpp Win32 Animation EXE scheme in 7.1 then you should now use the Cpp Win32 Animation scheme instead.
