I have been debating on "updating" my large static display for a number of years. I have even played around with a old version of the Light O Rama software (v3.12.0). Having made the decision to final go with LOR with the sales next year, I wanted to update my demo software. When I tried to delete the old software I got a error message saying "Another program is being installed. Please wait until that installation is finished and try again". No other program is being installed and I since finished installing some other new software with no problem. I took a chance and decided to try and download the LOR 5.3.8. This time I got a message saying "Error 1500. Another installation is in progress. You must complete that installation first before continuing".
Not being able to find any program installing, I tried downloading and installing a new media player. No problem. Tried LOR again, same messages.
