This error appears in Delphi 2009, ZEOSLIB_TESTING_REV779 and ZEOSLIB_TESTING_REV800.
While compliling Project Group we have all ok. But when we install ZComponentDesign120.bpl
we get an error
.The entry point in procedure @Zfunctionsconvert@initialization$qqrt not found in library DLL Zcore120.bpl
But if we go to Component - Install Packages, select ZComponentDesign120.bpl all components install correctly and work.
The same error appears then we open BDS.exe. In other words, every time when I start Delphi, I must reinstall ZComponentDesign120.bpl and then open my projects else I get an error "Components not found"
