Installation of 1.2.1 Hangs up

I download the new version of Siril 1.2.1 but when I try top install, my cursor spins a circle for a second an then never installs. I’m trying to install windows 64 Bit version.

I had to go back to the previous version which installs fine.

Any ideas?

No. The installation is done by a third party software. This is the same than before nothing has changed.

Must be my system, I installed the previous version and tried again. Same thing happened so I installed the older one and it is all good.

Try to uninstall all versions before and restart your computer. Then install the last version.
