How to use:
0) Install JA2 in a mod friendly location (NOT Progam Files(x86), Program Files or similar folders that are under special UAC protection since Vista)
1) Download the latest SCI
2) Extract the downloaded file over your JA2 installation, allowing it to overwrite existing files
3) Use JA2.exe to play

[TIP] If you are not asked wether to overwrite stuff, something is awry and you probably hit the wrong folder
If you are on Windows 8, please install the Windows 8 compatibility fix, to be found in the 'Docs' folder!

ummm... what is an 'SCI'???

FAQ
What does SCI stand for anyway?
Single Click Installer - While technically not totally accurate, it underscores the ease of use compared to other setup methods.

I can't open the archive!/What tool did you use for the archives?
The archives were packed with 7-zip 9.20 on 'Ultra' compression, older or different programs might have trouble with this.

The game still shows [some older version] on startup!
The version is written in one of the code files and only gets manually updated once in a blue moon. Don't Panic! The archive/file names are accurate.

Why isn't there any UB related stuff?
Because I didn't want to inflate the package unnecessarily.
Update: I started leaving the UB stuff in since I don't need to keep the 200MB limit imposed by MF anymore.

Will you update this thread?
No. At least not for every new version. I will announce new lines of packages and make additions to this post as required, but you'll have to simply check my skydrive for new releases.

Is there a changelog?
There are txt files with the svn log in every package.

What about savegame compatibility?
No guarantees. Developers try to avoid it for as long as possible, but you have to be aware that every update is a risk and make backups. It's the cost of using the cutting edge version.

What about compatibility with mod [x]?
Modders will generally specify a version of 1.13 that their mod was developed for. Unless you already are an experienced user, use that version and don't attempt to glue something together

I need further support!
Just ask here in the thread or visit the IRC channel #bearpit Note that the usual residents there are mostly European, 0300 GMT might not be the best time to look for support. Also, give some life sign when entering so we don't assume you're another lurker and don't worry if it takes a few minutes for someone to respond

to be continued...

Hey, thnx for the help but I tried using the INI editor and set the res to 1920x1080 but it always asks for 16bppp.

one more thing, it seems i have JA2 Gold. Now it mentioned NOTHING about being the GOLD version in GOG which has kinda annoyed me. There are many Gold versions of games that are significantly different.

It would make life a whole lot easier if i had this on CD, it really would. Having to uninstall, regclean, restart then go baxck to GOG to download/install takes some time, I tell ya.

Hello guys. Been looking two days now in the forum to find any solution, but did not find any instruction how to run the game or a mod on Win7. I cant even get the fresh install of JA2 to run. It says : D:.... \Jagged Alliance 2 \smackw32.dll is not to be used under windows or has a failure(translated from german...) So it say to reinstall again or ask system administrator. so what have i to do?

...
I´ve bought JA2 on GoG and tried to update to 1.13 like written above.
But still I´m getting this error message.
During extracting the 1.13 file was no prompt of overwriting file, though the path is correct (G\\JA2 in my case).
Running WIN10 64 bit, WIN8 reg patch is applied

Error message indicates that a file of the original game called [ambient.slf] is not found by 1.13's vfs initialization,
go to G:\ja2\data and check whether such a file exists, size should be 281098 Bytes(274 KiB), CRC32 is BBF861CE,
if not dld JA2 from gog again, either point to same folder but deny overwrite, or better dld & install JA2 and 1.13 both again.

If ambient.slf is present in \data check whether also folder g:\ja2\Data-1.13 is present,
if not probably something went wrong on install of 1.13, perhaps extracted to wrong folder
or no "restore path" option combined with "always owerwrite, no confirm",
for safety measures dld & install game and 1.13 again.
If file and folder are both present your vfs_config.ja2113.ini may be corrupted,
post it or here so we can check or, perhaps faster, dld 1.13 again install on top,
or both new to be on the very safe side.

Also if you dld something multiple times because of whatever suspect, like dld curruped,
compare size of both extracted contents and if equal compare crc/sha/etc, use hex editor,
or run [FC /?] at command promt to get info on binary compare of 2 files with windows onboard tool.
