From what i saw the patching method is pretty similar to the normall installer , which needs for whatever reasons 6GB on system disk(pretty insane for 2GB game). Dont know why devs choosed this sick method of installing/patching.

So I just did repack once again on v1.01 version in the end

That's because we got used to the "classic" file replacement Updates. Updates contained changed files and we pretty much needed just to install the Update were Update just replaced old files with updated ones.

From your words, this Update is actually a Patcher update.
It Patches the original files and to do that, it needs to back up the original ones so that, if there is a f*ck-up in the patching, it can easily revert the changes back to the original version in case of corrupted installation due to internet mess-ups.

I don't know if @NamelessOne will update the installer to support further updates but it would be nice if someone can make new conversion with proper reg entries in case OP does not do it... :)

the patch is trying to patch the installer itself(a copy of the I Am Alive.msi its stored on a special location on the hard drive) that was used to install the game, after that it will use the new patched I Am Alive.msi to install the game again, its a really idiotic system ;-)
(changed files have 30MB)
- so the problem are not reg entries but original installer/patcher

I will update the conversion. I would do it earlier but I just saw that there is an update for the game :D

Seems like this games conversion is cursed for me :-D Now i am getting this error while running it from ISO :-D
and it was working fine when i tried months ago on same machine :-D
so in the end i just made simple generic installer :-D

same here :(

IF Either of you took the time to actually read the entire thread you'd have found the reason it doesn't work from ISO, but did from HD.

You both have a file in the ISO that shouldn't be there!! Setup.ini is the guilty file. Look at BOTH ISS scripts, #define Internal which means that, that file will be compressed into setup.exe, along with the files from extracted setup.cab.

Just re-did conversion & installed perfectly from ISO without that file. IF I included it in ISO, generated that runtime error> access denied.

nobody is perfect :-D but thx for info

I've finally managed to install the damn game and update it to 1.01 version. Curse upon you, Ubicrap and your registry entries :D So, I've updated the conversion to CIU 1.0.0.6, changed the look of the installer a bit (looks better to me now :D) and changed the game version to 1.01. Enjoy ;)
