I bought my computer in 2008ish, maybe 2009, and it came with Windows Vista Home Premium 64-bit. It also came with pre-installed software, and of those pre-installed software included Microsoft Works Word Processor. I upgraded to Windows 7 Ultimate 64-bit last week, and I have been painstakingly installing my programs back after I messed up the installation. First, I installed Windows 7 Home Premium 32-bit, then I realized I put in the wrong disc so I then put in Windows 7 Home Premium 64-bit, then I upgraded to Ultimate 64-bit. All my programs got messed up in the process and I basically have a clean install of Windows 7 with a Windows.old folder containing my programs in a folder, which all need to be re-installed. I can see my Microsoft Works Word Processor, but it won't let me run the installation on it. I tried running it in compatibility modes for every available option, but nothing works. I also ran it as an administrator. How can I legally re-install these programs I purchased? I have tons and tons of .wps files that I want to be able to open with a program I purchased with my computer. Yes, I have heard of OpenOffice and it does not support .wps files. I do have Microsoft Office Professional 2013 installed, but it can't seem to open .wps files (unless I'm wrong).
