So what to do ?
No worries, here is how you can manually install any prior verion of DevExpress into D5. Use File/Open to open & recompile in the suggested order as below :-
1) XP Theme Manager - dxThemed5.dpk (RTL)
2) Xpress Common - dxComnd5.dpk (RTL)
3) Express GSI + Lib (dxGDIPlusD5.apk)
4) CxLibrary - cxLibmyclD5.dpk (RTL)
5) As for dxComnD5.dpk (need also to click Intall)
4) ExpressBars (need to recompile and install 2+2 dpk)
