Windows 7 Win 7 upgrade from 7048 to 7057 problems

[kaylix]

Actually, I had this problem with 7000 and 7022 as well.

• Insert DVD
• Launch setup.exe from within Win7 7048
• Click "Install Now"

Almost immediately I get:
"Windows Setup cannot find a location to store temporary installation files. To install Windows, make sure that a partition on your boot disk has at least 688 megabytes (MB) of free space.

Error code: 0x80070490"

I've done a full day of searching for more info online and really haven't found anything that relates to Win7. I have done the following:
Verify available space on C: (which is over 400GB free)
Checked permissions and ownership on temp folders (although it was never changed from the initial install)
Launch setup.exe as Administrator

The install will work if I boot from DVD but will not perform an upgrade, of course. However, a full install is possible to the same or secondary hard drive.

Any ideas are welcome.

It seems like you are encountering an issue during the installation process of Windows 7 with error code 0x80070490. This error typically indicates that Windows Setup is having trouble finding a location to store the temporary installation files during the upgrade process. Here are a few troubleshooting steps and suggestions you can try to resolve this issue: 1. Run Setup as Administrator: - Ensure that you are running the setup.exe as an administrator. Right-click on the setup.exe file and select "Run as administrator" to run the setup with elevated privileges. 2. Check System Requirements: - Verify that your system meets the minimum requirements for Windows 7 installation, including disk space requirements. Make sure that your system meets the minimum requirements for upgrading to Windows 7. 3. Temporary Files Location: - Check if the temporary files location is set correctly. You can change the temporary files location in the Windows Setup process. Try changing the temporary files location to a different drive or directory with sufficient space. 4. Try a Clean Install: - Since you mentioned that a full install to the same or a secondary hard drive works, consider performing a clean install instead of an upgrade. This will involve formatting the drive during installation. 5. Check Boot Disk Partition: - Ensure that the partition on the boot disk where Windows is installed has enough free space. Even though you have over 400GB free on your C: drive, there could be specific requirements during the upgrade process. 6. Use a Different Installation Media: - If possible, try using a different installation DVD or a USB drive to rule out any issues with the installation media. 7. Check Installation Logs: - Check the installation logs for more detailed error information. Sometimes, the logs can provide more insight into what might be causing the issue. 8. Install Windows Updates: - Make sure your current Windows installation is up to date with all the necessary updates. Installing pending updates might resolve compatibility issues. If none of these steps resolve the issue, it might be worth considering a clean install as an alternative. Let me know if you need further assistance or if you have any other specific details to share about your system setup.
