Comodo unite starts only under that profile where it was installed. Suppose on PC I have 3 user: User1, User2, User3. If I installed CU under User1 account, under User2 and User3 CU wouldn’t start automatically.
I try it on 2 PC under WinXP SP3 x32 and one under Win7 x64.
Use 18.104.22.168 version
In "Option-General-Startup" all box checked.
