Upgrading to Stars! 2.6b This patch only works with the registered version 2.50a exe. If your current version of Stars! is older than this, you will need to use the incremental patches to upgrade to V2.50a first, then use this patch. If your current version is newer than this, you should use the direct patch for your current version. To upgrade a registered copy of Stars! from version 2.50a to version 2.60b place patch.exe and stars26b.upd in the same directory as your registered version 2.50a of Stars!. Run Patch. Notes: Games started with V2.5, V2.5a, V2.6, and V2.60a are upgradeable to V2.60b in progress. Once you upgrade to V2.60b, you cannot go back to using previous versions. If you have both Stars! version 2.0b and version 2.60b on your machine at the same time Windows will only let you run one copy or the other unless you change the name of one of the executables.
