For some reason Shift+Check for update doesn’t always work on Vista, some people report success and others are having issues. I think this is an isolated issue to a few users. 


There are reports that these two fixes *may* work: 


1.Right clicking iTunes.exe, clicking on the compatibility tab and checking the “compatibility enabled” tick box allows you to ‘Shift+Check for update’, however yesterday, when I tried this, it just refused to start iTunes. 


or 


2. Run iTunes as administrator. 
- That means right click ur itunes program icon and press the option ‘run as administrator’ 
- Typically speaking the option doesn’t appear for shortcuts so open up your itunes program folder:


 Computer > Local Disk C > Program Files > Itunes 


Then right click on the file thats named ‘Itunes.exe’; then click ‘run as administrator’ wait for it to load and go through all the notifications, sometimes it says theme has been changed and vista home premium or business etc. looks like vista basic. Don’t worry, now use the shift + restore option. 


This will only work once, and then you will have to close iTunes and reopen as administrator 


Any other fix?…..Unfortunately at this stage you will need to find someone with either a Mac or XP/Win7 and use their machine. 


I have managed this on Vista without having to either of the processes above so as I say it is isolated to a few cases. If anyone else knows the answer please let us know.
