The Sims 3 Launcher Says 'Version Incompatible' After Uninstalling a Pack

Confirm this is EA's specific error path

EA ties the Version.tag step to an incompatible-version launcher error that can appear after an Expansion or Stuff Pack has been uninstalled and a leftover file causes an issue. If your error text or recent action differs, begin with EA's troubleshooting page instead of deleting unrelated files.

Apply the documented file check carefully

EA says the game automatically recreates Version.tag the next time it is played. This does not require deleting the whole Sims 3 folder. Make a backup before changing files and verify that the named file is the one being removed.

1. Close The Sims 3 and its launcher.
2. Open Documents > Electronic Arts > The Sims 3.
3. Locate the file named Version.tag and remove only that file; do not delete the folder or saves.
4. Restart the launcher and check whether the same version-incompatible message remains.
5. If it remains, stop repeating file deletion and use EA's current install/repair support for the relevant EA app, disc, Mac or console branch.

Check pack sequence without assuming every install is identical

EA's installation guide says to install the base game before expansions, stuff packs and worlds; it recommends physical packs in release order and says to launch using the latest installed expansion or stuff pack. It separately notes that PC disc installs do not update past 1.67. Record the storefront and pack list when comparing community advice.

1. Confirm the base game is installed before packs/worlds.
2. For a disk-based pack setup, compare the installed order with EA's oldest-to-newest recommendation.
3. Use the launcher entry for the most recently installed Expansion or Stuff Pack as EA specifies.
4. If the installation is from PC discs, account for EA's stated 1.67 update cap; do not describe that cap as an EA app limit.
5. Ask EA or players for help with the exact launcher text, install source, removed pack and installed pack list; never share a product code or EA password.
