First make sure you have a recent version. You can check your version in the title screen

Secondly, according the developer blog website one of the things the patch adds is this:
※ Begging "Plead 'Don't call the police'." at the event of sex development over 400.
Well, looks like the ver from OP is still 2.18. I just downloaded the base game 1.98 again to test (just played the game with just 2.16 and 2.18 patchs and didnt used the 1.42/1.43) and encountered the same problem like the fellow dude ragham faced. After reading again and again a few pages and after doing a test with these patchs, now the game works (maybe, i need to play the game and see if I still get the option problem with the Salaryman event) because I have now the title in the same form you have (but is 2.18 and I dont see in the OP a 2.19 patch or game ver). Anyway, maybe this could be usefull to the people and to ragham, this is how this need to be done to make it work (at least I did this and worked):
1-Download the Base Game (1.98)
2-Download both Patch Zips (Flower_Princess_Elulu_Patch_216_142 and Flower_Princess_Elulu-v2.18-update_patch)
3-Extract the Base Game where you want
4-Extract the Flower_Princess_Elulu_Patch_216_142, you will have two compressed zips named patch_ver216_v and patch_ver216_v_ver142_d
5-Extract the patch_ver216_v, go to the patch folder and copy all the files you find there and paste the files into the "patch" folder you can see into the base game
6-Extract patch_ver216_v_ver142_d, same as above, go to the patch folder and copy all the files and paste the files into the patch folder of the base game (it will ask you to replace files, do it)
7-Extract Flower_Princess_Elulu-v2.18-update_patch, you will have two compressed zips named patch_ver218_v--500 and patch_ver218_v_ver143_d--1000
8-Extract the patch_ver218_v--500, go to the patch folder and copy all the files you find there and paste the files into the "patch" folder you can see into the base game (if ask you to replace any file, do it)
9-Extract the patch_ver218_v_ver143_d--1000, again, go to the patch folder and copy all the files and paste the files into the patch folder of the base game (it will ask you to replace files, do it)
10-Now run the game (fp_elulu.exe) and will start patching the game. After patching, push the Ok green button and the game will close.
11-Run again the game and now you will see the title of the game with "FlowerPrincess Elulu -Violence Edition(v2.18) add Molestation Edition(v2.18)- Debug Mode(v1.43)" (in japanese at first, because we didnt add a english patch in this "tuto", but dont worry, go to the last option in the main menu called "Settei" (せってい), look at the ENG button, click there and now you have the game in english)
Again, hope this is usefull for all and to ragham, and remember guys, this is how I made the things to make it work, cant say if this would cause errors or a bad patching but at first looks well. Thanks osmcuser132 for the image, was very usefull.
