    2502, 2503 errors on Windows 7


    Since upgrading to Windows7 I have been unable to update software; at each attempt, I receive first a 2503 then a 2502 error, without explanation.
    -date and time are correct
    -happens whether virus and firewall are on or off

    -attempting to use the uninstaller program also fails.

    This is clearly a common problem judging by the number of queries, but I have yet to see any coherent solutions posted.

    fingers crossed!

    3. On the "Start" menu, click "Run".

    4. In the "Open" box, type "msiexec /regserver", and then press ENTER.

    Method 2

    Check permissions within the Installer folder. To do this, follow these steps.

    1. Click on Start and in the Start Search bar > type in > c: /windows/installer.

    2. Right click on c: /windows/installer at the top under programs and click properties.

    3. Click on the security tab > Verify if System and Administrator account has Full access permissions.

    4. The Everyone account should have read and execute permissions, List Folder Contents, and Read.
