Thank’s for the report! Recently Renpy split their 32 and 64 bit executables and the 32bit one has been getting flagged as a virus on a limited number of virus detection software (including windows base one unfortunately). There’s nothing we can do but hope that it’s eventually flagged as safe by windows in a future definition update and inform people that it’s expected behavior.
If you have 64bit system you shouldn’t need the 32bit executable anyway, if you do need it you’ll have to flag it as safe and restore it.
