If not, you'll need it installed to open a Word document. A suggestion, Don't install Office 97 on Vista.. Get a newer version as they're supported better and it will still open Word 97 documents. (There are a few other programs which will do the job also, such as the free "OpenOffice" but you'll still need to have it installed.)
As to the download, a couple of things come to mind..
1. Do you have a third party download accelerator installed? If so, remove it and try downloading again.
2. If you're only using Internet Explorer to perform the downloads, you may want to try installing a secondary browser to see if Internet Explorer is broken. Try downloading and installing the free Firefox browser from the link below and check for its ability to download files. If Firefox works, you may need to revert back to Internet Explorer 7 by uninstalling IE8 from the Control Panel-Add/Remove Programs section.
3. It's quite possible you are infected with malware.. Please follow the instructions below to install and run two free malware removal tools:
On a friend or family member's computer, download the Malwarebytes installer and update files from the links below, copy them to a CD or flash drive, then transfer the files to the problem machine and use them. If you can't start the computer into "normal" windows, try installing, updating, and running the scans AFTER the computer is started into Safe Mode.. I use the sites below to download the installer file and the manual updater:
Once downloaded and before transferring them to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.
Malwarebytes Installer Download Link (Clicking on the links below will immediately start the download dialogue window.)
Malwarebytes Manual Updater link
Next, download the SuperAntispyware program and the manual updater from the links below. After running the Malwarebytes tool above, if you still can't download and install it directly from the problem machine, download it on a friend or family member's computer as well. After installing and updating SuperAntispyware, run another full system scan and delete everything it finds as well. As before, you may need to rename the installer file to get the program to install.:
SuperAntispyware Manual Updater
In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder....
Hope this helps.
