KillerOh, you understand quite well. But only deads don't make mistakes. I've made tens of conversions and never failed, until now. So yes, it's my blame, but when I've said the uninstaller returned an error, nobody took pains to read what this error means.
Nobody realized such error even don't exist in Inno. Instead, you said I should take the conversion what it is, although error clearly sad there is a problem with generated uninstall script. However, one conclusion could be drawn: "take the conversion as is, because
peterf1999 can't be wrong". And now one love fella
