Spike recorder not opening

Hi, I used to have an older Spike Recorder version on my computer (v1.8), which worked to record from boxes with a USB cable. I was not able to get it to recognise Muscle spikerboxes when plugging into the speaker port. In an attempt to fix this issue, I removed the old version and downloaded the newest version from the website (v1.9.38). However, after installation, the program does not run (simply doesn’t open). I also found a link to v1.9.37, which has the same issue.
I am running windows 10 by the way (this has not changed between the two different Spike Recoder programs).
Thanks for any help!
