I won’t advise other users to deal with the company www.sysinfotools.com. I have purchased MS Office Repair File Software. I spoke with the online chat agent and he told me how to use it, but unfortunately the software showed that the file couldn’t be repaired. I checked again and again, but it showed that all my files were ok. When I emailed the online chat agent, he told that it was ok. But it wasn’t. My files were damaged, but the software didn’t repair them. Scam. Don’t waste money for the software.
