When attempting to install a new build of WKO4, some Windows users are receiving an error that states the new build cannot be installed while the .exe file is in use. This generally means that your antivirus software is "holding up" the WKO4 file; we often see this specifically with the LiveSafe antivirus software. Here's how to get around this error and install the latest build of WKO4:
- Download the current build of WKO4 directly from the server here: http://updates.wko4.com/wko4release/.
- Install the downloaded file.
If you still receive the error, restart your computer, temporarily disable your antivirus software, and try the above steps again.
