Hi!
First of all let me explain why commas appear in the File Version field when importing "install_flash_player_32bit.exe" package. When importing new software resource having EXE extension file version is actually taken from file properties of the package that is being imported. In our case the file version for "install_flash_player_32bit.exe" package is 11,2,202,235 (you can right click on the installation package, open Properties, on the Version tab select File Version list item,and the value for the File Version will be 11,2,202,235).
What about detection rules based on file version, File Version detection rule correctly detects installed software even if a file version in the rule is specified with commas instead of dots.
