Any shared libraries or whatever that might require a reinstall of 13 afterwards?
Also, since I have an upgrade version, might 13 not reinstall if I need to with 12 uninstalled? I had this issue ages ago when I upgraded to 12 or maybe 11 and didn't have the previous version. PD12 Ultimate Suite (upgrade from PD11 Ultimate). PhotoDirector 5. PowerDVD13. YouCam 5.
