                                        System Driver Cannot Be Uninstalled
Symptom:
System river cannot be uninstalled.
In order to confirm that this is the symptom, run the following command:
msiexec.exe /x {D6E2EDC1-E715-4822-821B-267B51F52862} /
lvx* 
uninstall.log 
 
   And then inspect the uninstall.log file. If you find something like the following:

  Solution:
- Log in to regedit
-  Add the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\DIFxApp\Components\{AAF65C8D-732B-4FA6-98B7-137AE4BB7596}
-  Add the following string value (REG_SZ) under DriverStore = C:\Windows\system32\DRVSTORE\igfxdcd_F3CCEDB5981DE64CA22972EB5A7C061E8376F890\igfxdcd.inf
- Try to uninstall again.
