Tell me if it's good or bad to have solved this way...

It basically created double backslashes in the log file

RegWriteStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{#AppName}_is1', 'DisplayIcon', ExpandConstant('{app}\{#E1[60]}\{#E1[61]}') )

so i had to change to

RegWriteStringValue(HKEY_LOCAL_MACHINE, 'SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{#AppName}_is1', 'DisplayIcon', ExpandConstant('{app}\{#E1[61]}'))

and this is where it now appears correctly in the log file,



please if you can ... do a test too I succeeded but you never know.

Thanks in advance to everyone.
