Upgrading to Stars! 2.6 This patch only works with the registered version 2.5a exe. If your current version of Stars! is 2.0 you will need to upgrade it to 2.0a first using the patch in STARS2AU.ZIP and then upgrade to 2.0b using the patch in STARS2BU.ZIP, and then upgrade to 2.5 using the patch in STARS25U.ZIP, and then upgrade to 2.5a using the patch in STAR25AU.ZIP. This patch can not upgrade versions older than 2.5a directly to version 2.6. To upgrade a registered copy of Stars! from version 2.5a to version 2.6 place patch.exe and stars26.upd in the same directory as your registered version 2.5a of Stars!. Run Patch. Notes: Games started with V2.5 and V2.5a are upgradeable to V2.6 in progress. Once you upgrade to V2.6, you cannot go back to using V2.5 or V2.5a. If you have both Stars! version 2.0b and version 2.6 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.
