{dcc64 Fatal Error} F1026 File not found: 'cxLibraryRS29.dcp' (VCL + DevExpress)

Question

Heyllo.

I just upgraded my project to Delphi 13 and latest DevExpress, but now I'm getting this new error in one of my frames:

[dcc64 Fatal Error] frameAdmin.pas(8): F1026 File not found: 'cxLibraryRS29.dcp'

Can someone please help me as to why I am getting this and how to solve it?

This is the top part of my frame where you can see my uses and things I am using from DevExpress:

Any help would be greatly appreciated!

• DelphiCoder: This error can have several causes. How did you install the DevExpress components? Did you miss to install a package or to add a search path?
• Shaun Roselt: Not sure if this is helpful or not, but cxLibraryRS29.dcp is for an older version of DevExpress/Delphi. The latest uses RS37 at the end and not RS29, because my installation of latest DevExpress 25.1.5 is under RS37.

Answer 1

Look inside your .dproj file. I suspect that there is a cxLibraryRS29 somewhere that is supposed to be cxLibraryRS37.

Simply try and rename it from cxLibraryRS29 to cxLibraryRS37.

If there are other DevExpress ones with RS29, also rename them to RS37.

• user31362432: Renaming all of them from RS29 to RS37 is what worked. Although I removed cxLibraryRS29 because it did not find a cxLibraryRS37. Thank you.
