Clear Cache If you cannot complete a download, you may need to clear the cache in Internet Explorer.
Follow the steps below to clear the browser's cache (note that this procedure will vary slightly depending on the version of Internet Explorer you have installed):
On the Tools menu in Internet Explorer, click Internet Options, then the General tab.
In the Browsing history section, click Delete.
At the Delete Browsing History dialog box under the Temporary Internet Files section, click Delete files, then choose the option for Yes if you would like to empty your entire cache of temporary Internet files.
In the Delete Browsing History dialog box, under the History section, click Delete history. When asked if you would like to delete the history of websites you have visited, choose Yes. When you are done, click Close.
Under the General tab, in the Browsing history section, click Settings. At the Settings dialog box, select Every time I visit the webpage. Set the disc space to use for the Temporary Internet Files folder to a size larger than your intended download. Next, click the View Files button.
At the Temporary Internet Files window that opens, open the Edit menu and click Select All. Press Delete. When you are asked if you would like to delete all cookies you have selected, click Yes. Click the OK button until you return to the General tab, and then click OK to close the dialog box.
Disable Automatic Termination
Another possible reason you are unable to complete a download is that your Internet service provider (ISP) may be automatically terminating your Internet connection after being idle for a specific number of minutes. Contact your ISP to disable the automatic termination of your connection when downloading files.
