FindBugsPortable 3.0.1 Development Test 2 English 5o6n2d

First of all, your link is broken as you have an extraneous <br /> in your link's href attribute.

Now onto the files:

appinfo.ini

• Why do you have the DisplayVersion as 2.0 Rev 3? Everywhere on the official website displays the version as 2.0.3 - this could cause s some confusion.
• You should add the following to your [Details] section:
  Trademarks=FindBugs is a trademark of The University of Maryland

launcher.ini

• Note that this app stores its settings in the registry under HKCU\Software\Javasoft - these will need to be handled.
• You can add DirectoryMoveOK=yes to the [Launch] section - it works fine when changing the path.

installer.ini

• It may be worth adding
  [DirectoriesToPreserve]
PreserveDirectory1=App\findbugs\plugin
PreserveDirectory2=App\findbugs\optionalPlugin
as findbugs does seem to actively plugins from their documentation, and s may not like losing their plugins if they update the app.
• You really don't need to have the [Languages] section - English and EnglishGB are the same as far as the Launcher and Installer are concerned, and the app itself is US English only.

appicon.ico

• You don't need a 24px or 256px icon at 8-bit, they will never be used by the launcher.
• You should have a 48px icon at 32-bit.
• Optionally you can include a 256px icon at 32-bit.
