for some reason my pc is having troubles with microsoft installer, and im wondering if there is any other ways to fix this, other than doing a windows 7 os repair from disk, and if i do a repair will i lose data? like documents and downloads?
ok so i tryed this and it didnt work, i did system restore and checked for errors but im still having problems, is their a certain option i do during repair thanks?
try and repair windows system files from the command prompt:
Start - type this in Search Box -> COMMAND find at top and RIGHT CLICK - RUN AS ADMIN
Enter this at the prompt - "sfc /scannow"
without quotes
restart
additionally your windows installer service might not be started:
a. Click On start; In the Start search, type Services.msc and Hit Enter.
b. Check if the entry Windows Installer's start up type is on Manual, otherwise right click on it >properties and set the start up type to manual then restart.
honestly I'd rather have you reinstall windows, if windows installer doesn't work your current installation of windows might have much worse problems than what you're having.
