As I am running the x64 version of XP Pro i often have to find different versions of the programs i use, such as itunes; Apple don't make a version for my OS, but do supply a x64 version for Vista - but the numpties don't let you install it on the XP x64... for seemingly no reason. So when I want to update itunes, i have to get the x64 version, unpack the exe file and edit the msi files using Orca, following the methods described here.
I've done this before to upgrade itunes and i have had no trouble, but when i tried to update to the latest version (9.0.1), it decided not to work. It gave an error about the Apple Mobile Device Support not being able to be installed on x64 blah blah blah, so i edited the msi for that and it let me go through with it, but as it got to the end of the installation (the starting services section) another error came up stating that 'Ipodservice failed to start. Verify that you have sufficient privileges...' which continues to pop up every time you click cancel on the window, until you press cancel on the installation window, which then rolls back the entire installation of itunes (Of course I have sufficient privileges on the computer as I am the administrator). After all this i attempted to open up itunes normally, and lo behold, it doesnt open. (I cant remember the exact error it gave me as i have now proceeded further)
I have tried several methods to solve this problem;
* Trying to reinstall again, with both the x64 version and the normal x32 version (which i also had to edit to allow me to install!).
Completely un-installing and re-installing everything related to itunes, quicktime, etc - using methods described here. Everything I have is completely up-to-date now, such as quicktime.
Ive tried system restore twice to no avail - each time i go back it just gives me the same errors
I have backed up everything that will allow me to re-instate my itunes library when i get it back up, but I'm pretty much out of ideas for this problem so any help is appreciated - apart from telling me to switch media players!
