Thanks for the suggestions.
Prior to posting, I had searched the registry with JVPower Tools, Tune Up Untilities 2008 and through Windows (regedit), searching for both Sonic and Roxio.
The only enteries are Legacy and can not delete them and dont appear related to installation- mostly emulation keys.
Using Windows Install Clean Up, Add/Remove Progs. and other system uninstallers (Revo, CCleaner), I can find no trace of Sonic or Roxio installations.
The Sonic BackUp MyPC, and this is just plain weird, starts up when I go to the task bar, right click and scroll to the top, to "ToolBars," the installer initiates right when the mouse touches the "Toolbar" carrot.
It does not start when touching or clicking onto any other selections (right clicking th task bar: Properties, Task Mgr, Lock Task Bar, Cascade Windoww, et) only the Toolbar selection at the top......
I am at a loss.
Would uninstalling and reinstalling Windows Installer help?
Any feedback appreciated.
