Windows 7 Unable to install various apps on Windows 7

[Cab00s3]

Sorry if this is in the wrong section, but my problem does relate to installing things on Windows 7 so thought this was the best place to post my query.

Anyway, I am getting code 2503 and 2502 errors whenever I try to install some apps(COD 4, AMD dual core optimiser, Company of Hero's etc...) Now from what I can tell, these errors stem from an incorrect time/date setting, but my time/date settings are correct!?(I even used the sychronise with windows server option). I then tried to edit the permissions on my Windows install folder(to allow myself full permissions in case that worked) and it wont let me edit any permissions! I am an Administrator on my PC, and the only account on it is the one Im using.

Any help?

PC SPECS :
Asus Crossfire I Motherboard
AMD x64 4000+
Asus ATI 3870
2 x 2gb Transcend RAM
Western Digital 640gb SATA
Seagate 80gb SATA

Edit: Ok, found out how to set myself as the 'owner' of the folder(Windows and Program Files(x86)), and set all the permission levels to full, but it STILL gives the same error. ANYONE know how to fix this?

PS: It threw a bunch of errors when it was trying to change various Microsoft related folders inside the 2 mentioned above. I just told it to continue making the changes

It sounds like you're encountering some frustrating issues with error codes 2503 and 2502 when trying to install certain applications on Windows 7. These errors can indeed be related to permission problems, but the solutions can be a bit tricky. Let's address each of your concerns step by step:

Error 2503 and 2502:​

These errors often occur due to permission issues or problems with the Windows Installer. Here's a common method to troubleshoot and resolve these errors:

1. Run Installer as Administrator:
   • Right-click on the installer file and select "Run as administrator."
   []Check Windows Installer Service:
   • Make sure the Windows Installer service is running:
     • Press Win + R, type services.msc, and press Enter.
     • Look for "Windows Installer" in the list of services and ensure it's running.
   []Check System Date and Time:
   • Ensure your system date and time are correct. You mentioned you've already synchronized with the Windows server, which is good.
   []Reset Windows Installer:
   • Resetting the Windows Installer might help:
     1. Press Win + R, type cmd, then press Ctrl + Shift + Enter to run as administrator.
     2. In the command prompt, type:

         net stop msiserver net start msiserver

   []Check for Software Conflicts:
   • Sometimes, conflicting software can cause installation errors. Ensure no other software is interfering with your installations.

     Permission Issues and Ownership:​

     It's positive that you managed to set yourself as the owner of the folders and adjust the permissions, but the issue persists. Since you encountered errors specifically with Microsoft-related folders, it's possible that additional steps are required:
   []Run Installation Troubleshooter:
   • Windows has a built-in troubleshooter for fixing installation issues.
     • Go to Control Panel > Troubleshooting > Fix problems with Windows Update.
   []Safe Mode Installation:
   • Try installing the apps in Safe Mode to avoid any conflicts with other software that might be running in normal mode.
2. Verify User Account Control Settings:
   • Ensure that User Account Control (UAC) settings are not preventing installations.

     Additional Tips:​

     • Before making significant changes, consider creating a system restore point.
     • Check if there are any specific instructions provided by the applications' support or forums regarding these errors.

Trying the above suggestions should hopefully help resolve the installation issues you're facing. Let me know if you need further assistance or if you encounter any other issues during the process.
