World Wide Telescope Error 2503 and 2502 RRS feed

  • Question

  • Installation Error codes 2502 & 2503
    MY OS is Win 8.1 Pro 32 bit with  updates installed.

    Over the last few days every time I've been  trying to install  World Wide Telescope 5.0  I  get error codes 2502 and 2503.

    Can someone please tell me what these codes relate to, and how to overcome this problem?

    Advice would be greatly appreciated.

    Thanks: Don

  • This is probably not a WWT issue, but a Windows Installer issue. You can find the fix here..


    Please let me know if this helps.

  • 1) search for World Wide Telescope 5.0 installer and locate it.

    2) search for cmd, click right on it and "run as administrator"

    3) write full path of installer ex: c:\windows\setup.exe and press enter
