VCL UI Pack incomplete

In the current Setup of TMS VCL UI Pack the .pas files from xlsAdapter are missing and the compilation of the TMSVCLUIPackPkgXlsDXE12.dpk fails:

TMSVCLUIPackPkgXlsDXE12.dpk(87): error F1026: Datei nicht gefunden: 'xlsadapter\tmsXlsMessages.pas' [C:\Users\adrian\Documents\tmssoftware\TMS VCL UI Pack\TMSVCLUIPackPkgXlsDXE12.dproj]
Die Erstellung des Projekts "C:\Users\adrian\Documents\tmssoftware\TMS VCL UI Pack\TMSVCLUIPackPkgXlsDXE12.dproj" ist abgeschlossen, Build Ziel(e) -- FEHLER.

I cannot see the xlsAdapter folder would be missing. We have also not a single similar problem report. Can you verify if there isn't 3rd party software like antivirus / websecurity tools that interfered with our installer? Try to disable this and rerun the installer.

running the setup without removing the previous installation fixed the problem. Now the .pas files are in the folder.

I cannot understand this.
The XlsAdapter folder is included with the installer, also with the latest one.
I can only think something interferes on your machine, preventing extracting the files.
