I changed the script according to your proposal toQuoteIf,%SourceArch%,Equal,x64,Begin %ProgramEXE%=%ProgramEXE64% %ProgramTitle%=%ProgramTitle64%End
If,%SourceArch%,Equal,x64,Begin %ProgramEXE%=%ProgramEXE64% %ProgramTitle%=%ProgramTitle64%End
QuoteIf,%SourceArch%,Equal,x64,Begin Set,%ProgramEXE%,%ProgramEXEx64% Set,%ProgramTitle%,%ProgramTitlex64%End
If,%SourceArch%,Equal,x64,Begin Set,%ProgramEXE%,%ProgramEXEx64% Set,%ProgramTitle%,%ProgramTitlex64%End
yet another winbuilder bug ...Thanks for feedback, I workaround the trouble
Just to see and for the next time, I tried also with this workaround to DirCopy, that also works
ps: In a future version, when you, we have time, we can perhaps gained a bit of space by removing 32 or 64 bits files (eg: Totalcmd/Totalcmd64), not tested.
