    Error 2503


    Hi, this is on Windows 8.1 Pro, 64 bit. Anytime I try to install something I get that installer error, 2503, and then the install exits. I've searched quite a bit for this but no love.
    Any ideas?

    Have you tried running the install as 'Administrator'?

    You could try:
    1. Goto TaskManager > Details >
    Explorer.exe & click on End Task.
    2. Now Click on File in Task Manager > type Explorer.exe -- Check the box below shows as ( Create this task with administrative privileges.)
    3. Now install.

    OK, I can install that way. That's a nice work-around. What do you think is causing the problem? Permissions issue?

    If i'm honest i'm not entirely sure.

    If you reboot now and try again without doing the work-around above does it work?
    (obviously no permanent changes have been put in place to actually fix the issue... i'm just clutching at straws )

    One more tidbit; this only seems to happen with .msi files.

    Maybe try running the following commands to re-register the windows installer

    Windows Key + R >> msiexec.exe /unreg >> Click OK
    Then
    Windows Key + R >> msiexec.exe /regserver >> Click OK

    Try installing again (once explorer is running as you and not administrator)

    Installation Error codes 2502 & 2503 on Windows 8 Pro | Microsoft Surface tablet

    I know it mentions 'Surface' but the principle is the same (I believe) If not I'm out of options

    You're my hero! It was the Windows/Temp folder. I changed the permissions on it to administrator and all seems well. Thanks!
