My question is after installing the yodm-3d-crystalxp and visual-tooltip-crystalxp it was fine.but do i need to reinstall it again-again cause after rebooting my system i find it missing.Maybe there is other methods that i did not do which causing this problem that your side can guide me..

What do you mean ? ... Missing ?

it's not on the taskbar...not starting up... need to reinstall it back for enabling it...not like the rocket dock docklet and y'z shadow the software startup well and still in the taskbar and working fine...

When you shutdown you computer to reboot it closes everything including Yod'm 3D.
To re-open Yod'm 3D:

1. First go to the folder Yod'm 3D is in.
2. Then double click Yodm 3D.exe and Yod'm 3D will re-open.

If you want you can make Yod'm 3D re-open by it self when you computer starts up.
To do this:

1. Right-click Yod'm 3D's icon in the taskbar.
2. From the list click options.
3. Check the box that says "Start with windows"
4. Click OK

I hope this works  ,
