Hi there, Yesterday, I needed to run my Office Word. It normally loads up pretty fast. But this time, when i clicked it, a windows installer window came up saying that it's "preparing to start". Aftter that, another window came that said "The installation source for this product is not available. Verify that the source exists and that you can access it." Now, it had been installed previously and worked great, but it stopped randomly. When i went to uninstall it and then reinstall it, in my add/remove programs the simple "Microsoft Office Enterprise" was divided into multiple different "microsoft offices". Also, there wasn't a remove button for any of them. So i tried to uninstall it using ccleaner; when i press run, a windows installer window comes up saying are you sure you want to uninstall this program. When i clicked yes, it says again "The installation source for this product is not available. Verify that the source exists and that you can access it." Help please.
