Username shorter than 3 chars breaks install

When the BitNami Tracks installer prompted me for a username, I entered my typical local username of “sf”. Later on, I got the error message below. When I try to reinstall, it longer asks for a username, but I still receive the error. I’m not sure how to change the username or what to do about this, as I’m using BitNami specifically because I didn’t want to bother with a complicated installation.

Error message:

First four lines:
Problem running post-install step. Installation may not complete correctly
Error running C:\Program Files\BitNami RubyStack/apps/tracks/scripts/create_user.bat :

Hi,

Thanks for posting it. The installer should show a warning to not use a username or a password shorter than 4 characters. We will fix it for the next release.
