S4Real has Vishnu Launcher as Meows mention. S4real also has what he originally developed -- the Vishnu Packer. It is free and you can find it
here for download. This also launches your game as well.
If you are interested only in one of the free packers/launchers, I would simply download them all and then try them out yourself. After all, they are free.
FPSC V-Packer has a trial version for you to download and the "pro" pack (Smart Packer) does as well. So I would download those and give them a spin.
There is one more that was not mentioned. It along with Vishnu Launcher are the two least expensive products. The other one that was not mentioned is the InterFPSC Launcher that can be found
here.
Unfortunately there is no trial version. When the price goes up on this application after the introductory price expires it would be nice if there were a trial.
Vishnu launcher is $5.00 and depending on the money market rates the introductory price for InterFPSC is between $10.73 and $11.25. I had to pay $11.25. I believe, after July 1st, it will go up about twice the 6.99 it is currently at. I don't know if that is British Pounds or Euro. To be fair I also bought Vishnu Launcher. I try to support the community in this way as well.
If I had the time I would give a review of them all but I don't. This is one those times when a review would be great but there should be no actual ratings because they are all different an have their own unique features although the main feature is to pack and launch a game.
