Installing 0.9.21.11487 fails with an error, "Invalid use of argument 'Silent'" when it tries to install the flash player. It looks like there are no quotes around the exe path prior to the /Silent command. For example, mine showed:
Execute: C:\users\khadmin\AppData\Local\Temp\install_flash_ player.exe /Silent
Which I think should actually include quotes:
Execute: "C:\users\khadmin\AppData\Local\Temp\install_flash _player.exe" /Silent
Anybody else have this problem??
