UnInstalling MSI

Ordinary UnInstalling MSI anybody can do it from control panel
some times the MSI will not get uninstalled it throws some fatal error exception and we can't remove from add/remove programs. This happens mainly because of two reasons

1)By mistake removing the registry entries of that software from registry
2)Removing the physical files without uninstalling :)

Sol:-

For every .MSI we there will be something called product key registered in the registry

Mycomputer
|
|__hkey_local_machine
|
|__software
|
|__microsoft
|
|__windows
|
|__currentversion
|
|__uninstall


find the registry entries for that particular software check for the key

"MODIFYPATH" copy value it will be something like this





MsiExec.exe /I{265E7147-C7BA-4660-AF4D-1A1531F6E566}

change the it to

MsiExec.exe /x{265E7147-C7BA-4660-AF4D-1A1531F6E566} DISABLEROLLBACK=1

copy paste it in commadprompt

and run it. Uninstaller will start.
