Hi Johan,
I've uploaded a perl GUI program: https://www.squirrel.nl/pub/xfer/uploads/3C6TeP1OMnL8q7ciPFkyneaA.exe
this is made with 64 bit Perl. My launcher currently supports only 32 bit Perl because the 64 bit version was even slower running ExifTool.
It is not exactly a trivial program, but all the application stuff is within a single folder lib/App/Music/ChordPro . BTW when running unpar.cmd I get an error message "The syntax of the command is incorrect" on line ren %PAR_GLOBAL_TEMP%\inc\script\*. *.pl
I see. This was for ExifTool.
Note that unpar.cmd does not extract the Wx libraries.
It seems that unpar.cmd can't be used with your project. I'll have a look at it tomorrow and report my findings. Oliver
