Capitalism Lab Patches
Capitalism Lab is patched through its launcher, so in normal use there is nothing to download by hand. This page explains how patching works, what to do when it does not run automatically, and where the patch notes are posted.
Patching happens automatically
When a new version is released, the launcher applies the patch the next time you start the game. If the new version can still read save files from your current version, this happens without asking.
If the new version is not compatible with your existing save games, the launcher asks first, so that an update cannot strand a game in progress. Choose No and the game starts as before; an [Upgrade and Login] button then appears on the login screen, which applies the patch whenever you are ready. If you have still not upgraded after five days, the launcher reminds you again.

If you need the full installer instead
Patching through the launcher requires a working installation. If yours is missing, damaged, or on a new machine, install the current release from scratch:
Download Capitalism Lab (version 12.0)
Capitalism Lab requires a registered account to play. If you do not have one yet, see Buy Capitalism Lab.
Save game compatibility
Save files are compatible between incremental updates within the same major version. The major version is the first two digits of the version number — in 9.1.71 that is 9.1 — so a game saved in 9.1.50 opens in 9.1.71, but not in 10.0.
If you have a saved game from an earlier release and want to carry on with it, install the matching version rather than patching forward:

Patch notes and beta patches
Patches are announced on the Capitalism Lab forum. Release-version patches are posted as they go out; the beta board carries the post-release test builds, which arrive earlier and are worth following if you want fixes before they reach the general release.
