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.
