Troubleshooting Problems Opening LCS Files


Common LCS Opening Problems

Act! Removed

You encounter an error message such as "%%os%% Can't Open LCS Files" when trying to open your LCS. Usually, this is because you do not have Act! for %%os%% installed. The typical path of opening your LCS with a double-click won't work because %%os%% cannot make the program connection.


Tip: When you have another program installed that you know will open your LCS, you can select it from the other programs listed (see "Show Apps").


Wrong Version of Act! is Installed

It is possible that your version of Act! isn't able to open your ACT! History Data file due to incompatibility. Visit the Swiftpage, Inc. website to download (or purchase) the latest version of Act!. Your ACT! History Data file was probably created by a newer release of Act! than what's currently installed your computer.


Tip: Sometimes you can get a clue about the version of LCS file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


Ultimately, most of the difficulties opening LCS files are due to having the wrong version of Act! installed.


Additional LCS Opening Issues

In the majority of cases, installing the right version of Act! will resolve your issue. If you're still experiencing problems opening LCS files, there could be other computer problems. Issues that aren't software-related:

  • Invalid LCS file references in the Windows Registry (the "phonebook" of the Windows Operating System)
  • Unintentional removal of the description of the LCS file inside the Windows Registry
  • Partial installation of Act! that did not fully complete
