Erika Hello, this is often caused by an antivirus or firewall modifying Spine's files. Please follow the instructions here: Spine Troubleshooting: Antivirus and anti malware
Hzt I used the spine installation package downloaded on June 10 to install without any problems, but the spine installation package just downloaded today will have the problem in the picture
Erika I just tested it on my end and it downloaded and run just fine. I suggest to verify that nothing is interfering with the download on your machine. (such as an antivirus or firewall)
