JASP 0.13 install (64bit Win)
I'm not sure if this is just me and my setup, but I'm posting here in case it helps anyone else.
I just tried installing 0.13 (July 2020) to upgrade my old installation of JASP. The MSI seemed to work, but JASP was still at the old version and kept prompting me to upgrade.
Solution: During installation I chose a new path. The installer then ran fully, deleted the old version of JASP from the old folder and correctly installed the new version, which now works.
