      Special Upgrade 4 Tech Tips   12/27/2016

      Hi all! Now that Upgrade 4 is out and about in large quantities we have now discovered a few SNAFUs that happen out in the scary, real world that is home computing.  Fortunately the rate of problems is extremely small and so far most are easily worked around.  We've identified a few issues that have similar causes which we have clear instructions for work arounds here they are: 1.  CMRT Windows customers need to re-license their original key.  This is a result of improvements to the licensing system which CMBN, CMBS, and CMFB are already using.  To do this launch CMRT with the Upgrade and the first time enter your Engine 4 key.  Exit and then use the "Activate New Products" shortcut in your CMRT folder, then enter your Engine 3 license key.  That should do the trick. 2.  CMRT and CMBN MacOS customers have a similar situation as #2, however the "Activate New Products" is inside the Documents folder in their respective CM folders.  For CMBN you have to go through the process described above for each of your license keys.  There is no special order to follow. 3.  For CMBS and CMFB customers, you need to use the Activate New Products shortcut and enter your Upgrade 4 key.  If you launch the game and see a screen that says "LICENSE FAILURE: Base Game 4.0 is required." that is an indication you haven't yet gone through that procedure.  Provided you had a properly functioning copy before installing the Upgrade, that should be all you need to do.  If in the future you have to install from scratch on a new system you'll need to do the same procedure for both your original license key and your Upgrade 4.0 key. 4.  There's always a weird one and here it is.  A few Windows users are not getting "Activate New Products" shortcuts created during installation.  Apparently anti-virus software is preventing the installer from doing its job.  This might not be a problem right now, but it will prove to be an issue at some point in the future.  The solution is to create your own shortcut using the following steps: Disable your anti-virus software before you do anything. Go to your Desktop, right click on the Desktop itself, select NEW->SHORTCUT, use BROWSE to locate the CM EXE that you are trying to fix. The location is then written out. After it type in a single space and then paste this:

      -showui

      Click NEXT and give your new Shortcut a name (doesn't matter what). Confirm that and you're done. Double click on the new Shortcut and you should be prompted to license whatever it is you need to license. At this time we have not identified any issues that have not been worked around.  Let's hope it stays that way Steve

Open source for EOS

8 posts in this topic

Since EOS development is effectively done, how about releasing the game as open source? A lot of the topics for improvement that have been discussed here could be addressed that way.

Hi Jeep.

I have a contract with Battlefront for a period of three years. We're currently getting close to the two-year period (it was released in November 2009). There may also be some third-party deals as well. While I don't have any particular problem transitioning to open-source, I want to make sure I'm not harming or undermining any of the other parties involved. So, transitioning the entire game to open-source* is unlikely to happen before November 2012.

* I say "transitioning the entire game to open-source" specifically because it would probably be fine to release parts of it as open-source.

Brit, what about you collaborating with others under Battlefront NDA to continue with some EOS development?

As an example, Matrix/Slitherine has a group of modders who have released a custom mod Grand Strategy 2.0 for Commander Europe At war. They apparently have access to the source code for some editing to enhance the scenario editor capabilities, thus provide some additional features to their custom mod. Apparently all done with the approvals of all concerned.

Just a thought.

By the way, a few weeks ago, I created an open-source project for the AI. I'm still working through getting the code to work properly (mostly problems with naming collisions), though, so the project doesn't actually have any source code in it. I figured I'd delay mentioning it until there's actually some code there to play around with. The new AI will run in a separate DLL, so players with C++ knowledge can have compile a new AI and get their copy of EOS to run their version of the AI.

That sounds like it will be interesting to play around with :)

I'm guessing you haven't had time to work on the PBEM sync thing, but I thought I'd ask anyway.....

Wait, which PBEM sync thing?

The issue where the different players games can get out of sync. It happens to me all the time if my stupid dell crashes right after processing the turn but before I hit the save button. The other players will get 2 sets of events for the turn, since when I reload the game it has to calculate the turn again.

I think it can also happen when one of the other players (not the host) thinks it sent the event file but the host doesn't receive it (corrupt file on the server or some other issue). In that case it just seems like that player starts seeing weird behavior.

All sorts of strange behavior follows that.....

BTW, the crashes don't seem related to the game. It is some mysterious dell problem that happens every so often.

The latest update has improvements to make the PBEM games more stable (the game will automatically re-download game events if they are corrupted during download; the game autodetects corrupt events using a checksum), but that particular problem wasn't addressed. I have an idea about how to fix it, but haven't thought through the fix enough and haven't changed any code. (Sorry)
