I cannot change the location for Kaluach3. The instructions do not match the software. Location doesn't work for zipcode 89441.
If you have problems with the software, then I recommend downloading the latest version to update the current one installed on your computer or making even more comfortable: remove the previous version and directly install the next one provided on the page below. There is no other troubleshooting for this issue.
