Error 1500

Hi Frank,.
Welcome to Microsoft Windows Forums!

I would like to gather more information about the issue.

Ø summers - get you this error during the download or installation?

Ø what application are you trying to download?

In the meantime, you try these methods.

Try to put your computer in clean boot mode and check if the problem persists. To help resolve the error and other messages, you can start Windows Vista or Windows 7 by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts. This article describes how to solve problems in Windows Vista or Windows 7 by performing a clean boot.

Steps to put your computer in a clean boot:

1. click on Start
2. type msconfig in the Search box and press ENTER.

If you are prompted for an administrator password or a confirmation, type the password, or click continue.

1. in the general tab, click Selective startup.
2. under Selective startup, clear the Load Startup items check box.
3. click on the Services tab, select the hide all Microsoft Services check box, and then click disable all.
4. click on OK.
5. When you are prompted, click restart.
6. after the computer starts, check if the problem persists.

NOTE: TURN ON YOUR COMPUTER TO A NORMAL STARTUP AFTER TRYING THE STEPS ABOVE.

Click Start, in the search box to start, type msconfig and press ENTER.
Select Normal startup, and then press apply and OK
