@Diovanlestat - I really don't know what's happening. The log file tells me that everything is perfectly fine, except that the game starts and then immediately stops after few seconds. I have no idea why the game stops so early. You have the correct folders in your computer, and the registry is correctly managed by the AGS.
Have you copied anything in the Downloads folder of the AnyGameStarter1 game?
I see from the log that you created a "mini-game" containing all the EP and SP; have you tried creating a game with only Mansion & Garden?

P.S. Are you running the game and the AGS with an administrator account?

This doesn't bother me and if it's only happening for me I don't care, but I have what is supposed to only be the base game and M&G but the Holiday Stuff is also included (Make the holiday cookies, throw a New Year Party). I'm playing with the language set as German so I am not sure if that has anything to do with it.

EDIT to say that I really appreciate this being available to the UC. My desktop broke so I'm playing on a laptop so being able to only install the basegame plus M&G makes the game run much smoother.

For others on Windows 7, remember that Windows 7 is really, really stupid about trying to 'fix' things for you. Every third or fourth time I run an AGS, the operating system decides that the 'Documents' should point to just the AGS, instead of the entire 'My Documents'. At this point, nothing but the one AGS game that's now visible in 'Documents' will run, AGS can't find 'My Documents' to make new games, Sims 2 itself can't find the main game, SimPE can't find the game, HoodChecker hangs and crashes . . . (I haven't tried HoodReplace, Delphy's Download Organizer, LotAdjuster lately, but I'd assume they'd have the same problem finding where the heck the game went.)

It isn't every time, it's just enough of the time. I usually figure out it happened again when HoodChecker crashes, because I'm kind of obsessed with running it between every play session.

To fix this, open 'Documents', tell it to remove the location that's there, and then tell it to put in the whole 'My Documents' location.

This will also make it possible to run SimPE and HoodChecker again.

At least Windows 7 plays nicely with Sims 2 otherwise!

Thanks Numenor for having a look at more code. I'm glad to know it's not AGS. It's my set it, I got a confused network.

Thank you Numenor, ever since my disk drive died I've been wanting a UC compatible version. Now to really test things.

Seriously ... THANK YOU.
And welcome back.

For the most part I really do love this, but I keep getting "do you want this program to edit your registry" pop-ups multiple times both starting and throughout play... also, I can't install Sims, at all. Like, the installer works and the custom content for that game transfers, but the sim itself doesn't. Is there something I'm doing wrong?

I am getting the constant registry popups also. It's annoying. I am not sure how often they occur while AGS runs, but I seem to always get two more popups after shutting down.

Otherwise, the program has been working for me so far...although I have just been asked to re-identify my documents folder path, so am about to restart and, fingers crossed, all will be well there.

Edit: So, restarting seemed to work fine. However, I can no longer open my normal game in either fullscreen or windowed version. I use shortcuts which bypass the launcher, both of which now lead to my AnyGame2 (windowed). What do I do about that?

I think I must have messed up the path thing. I then had two UC folders for each of the Anygames I had created. The second one held the lots I had tried to install, but those lots/cc were not available in-game - perhaps the game was referencing the first UC folder? I have uninstalled the AGS to get back my normal game, and will try afresh later.

Further Edit: Installing a lot (by drag-and-drop onto the Anygame icon) is causing the extra UC folder to appear. The new folder contains only the Downloads and Teleport subfolders with the lot contents. Moving the contents into the original UC folder does make the lot/cc appear in the Anygame, so there is a workaround. The extra folder has the TM superscript in the title, while the original folder does not.

Another issue is that my Empty Anygame is still created with one subhood. When first loading, it says 'creating exotic destinations', and there are .package and .png files for Suburb001 in the Neighbourhood folder. I am creating a subhood template using Mootlida's tutorial here, and need a truly empty base to work from. The empty hood worked well in an Anygame with just Base/Uni/MG, but with all EPs ticked, the suburb appears.

More Edit: I know I may be whistling into the wind, but the saga continues...
I beleive this is the same problem reported by someone else up-thread. The Anygame starts and plays fine the first time, but thereafter, claims not to be able to find its path. Pointing it manually at hicon.exe (as it requests) makes no difference. Restarting the computer makes no difference.

Some further info...
I kept striking the missing file path error every now and then, but it seems to be fixed now - after clicking' Run as Administrator' in the AGS shortcut. It should have been running that way already, but perhaps it needed telling an extra time.
The AGS is still creating the extra Ultimate Collection subfolder when installing Sims2Packs. Annoying, but now that I know to look for it, easy enough to just move the contents to the 'real' folder. I wondered if I should rename the original folder to match, but no doubt that would mess up something much worse!

Update: I struck the missing file path problem again when I wanted to make a new AnyGame. I can't cancel out of the error, and although it says to identify the path carefully, and I try, I believe I am getting it wrong, because I don't know how to tell what the real path is supposed to be. Consequently, weirdness has happened, and I probably need to reinstall the AGS again to get back to the status quo.

Also, the AGS triggers the regedit message once for every time I open or close an AnyGame.
