    Error codes 2503 and 2502 prevent software to be installed


    Hey all.

    Today I did a fresh install of Windows 8 build 9200 and I'm really liking it. However, there's one small problem: a lot of software can't be installed due to the repeating occurrence of error codes 2503 and 2502.

    2503: something about Runscript
    2502: something about InstallFinalize

    I read that this happens because of an incorrect system date and time, but they are in fact accurate on my machine.

    Look at posts 7 and 14 here: Error code 2502 and 2503 [moved from Vista/7] - Tech Support Forum - old thread but principle still applies.

    Thanks but none of those methods work. Also, there does not seem to be a "installer" folder in c:/Windows even with hidden folders enabled.

    Well I tried. Hopefully someone will have an answer. You are doing this as a user with Admin rights I assume?

    Yes, it's there.

    You need to show protected files as well. But you can get there without doing that, just open Explorer, and in the address bar type C:\Windows\Installer

    Thanks, but I've decided to reinstall Win8 now. Much easier/faster.

    All works fine now!

    I have the same problem with msi and error codes 2503 and 2502, but I really don't want to reinstall everything.

    I have seen many with the same problems, but so far not one of the 'solutions' I've seen actually works.
    For a while it worked to log into the hidden Adminstrator account, but now with the HTC Sync Manager that workaround didn't work any longer neither

    I thought the purpose of error codes should be to tell about what causes the problems, but those codes apparently give no such clues?

    I found it


    The error Appears because you don't have that right. So what i did is make the administrator account (Youtube it forgot how to enable it.) then install the program to the location you want and copy the shortcut to your account (user file in local disk)
