Help installing the game

Hello everyone, I've been trying to install the game over and over and I just can't do it, every time I lunch the game I get this:


and this is how the directory of the game looks


What I tried so far:

Unpacking:

backgrounds_03.08.16.7z.001
backgrounds_03.08.16.7z.002
graphics_03.08.16.7z.001
graphics_03.08.16.7z.002
sound_09.08.16.7z.001
sound_09.08.16.7z.002
sprites_03.08.16.7z.001
video_03.08.16.7z.001
scripts_26.04.18.7z
Windows XP SP3+ 32-bit

Then i extract and overwrite the files it asks me to overwrite...

extra_28.04.18.7z

Error.

Then I tried the same but before adding the extra folder I added all the chiru_01.07.17.7z.001 002 etc content..

Same error.

I tried without the extra content it says "invalid luncher directory"
I tried with chiru files only with the extra files, "invalidad luncher direct"

I don't know what to do anymore!!!!

My OS: Win7 64 bits sp1.

Hi, I think you could have messed up the right magic extraction sequence. Try to cast the spell as follows:

• backgrounds_03.08.16.7z.001
• backgrounds_03.08.16.7z.002
• graphics_03.08.16.7z.001
• graphics_03.08.16.7z.002
• sound_09.08.16.7z.001
• sound_09.08.16.7z.002
• sprites_03.08.16.7z.001
• video_03.08.16.7z.001
• Chiru updates
• extra_28.04.18.7z
• scripts_26.04.18.7z
• Windows XP SP3+ 32-bit

I did it in that exact same order,
background
graphics
sound
sprites
video
chiru (overwriting files)
extra (overwriting files again)
scrips
.exe

same message

I'm going crazy here...
Maybe I don't have to overwrite the files?

Hm, no, you actually should merge files and overwrite updated ones. The message is given when one of the following files is missing/has invalid size. Perhaps you could get an idea from the list?
"graphics\locale\project_logo.png"
"video\sub\both_eng.ass"
"video\sub\58_both_eng.ass"
"sound\bgm\Treasure.png"

"sound\bgm\op.ogg"
"graphics\locale_en\end_4a.png"
"sound\voice\01\51500238.ogg"
"game.hash"

There is no file called game.hash or i cant find it

game.hash should exist in game root and is located in extra_28.04.18.7z. I guess it is the issue.
Actually, we plan to release ep6 next week, so perhaps you should stay tuned for an update after you solve the issue.

ok, for some reason I was using extra_06.01.17.7z (which i downloaded yesterday from the site)
Now I downloaded extra_28.04.18.7z again and everything works fine except for:

graphics\menu_en\r_click_menu\chapters\5_03.png and it's says that the size is incorrect or something like that

but at least the game runs now
thanks for all the support.

EDIT: I re-re-re-re overwrote the chiru update and now for some reason everything is fine with no errors... this was really tiring
and again thanks for the help!
