Most come with a demo version that expires very quickly. Also your post didn't write you removed those trial versions (something that I find very important today) and install your Office from your Office CD.
I have a new laptopt with Windows 7 and Microsoft Office 2010. My old laptop is running Windows XP. When I first transferred my word and excel files to my new laptop, everything seemed to work fine for about a week. Then, I had problems where I could not edit and save these documents without getting an error coming up. I tried to change all of the files on my new laptop so that I was the owner and had permission to edit and save the files. This worked for a couple of days, but then the same thing started to happen where I couldn't edit and save these files without doing "save as" instead. Even when I tried to save new files that I made on the new laptop to the transferred folder, I would be prompted to "save as" instead of save, and then everything would usually freeze up when I pressed the save as button or tried to type the file name. I tried to change ownership and permission of the folder and files yet again, but it has not seemed to work. Today, when I opened up one of the many "save as" files I had to make before, I cannot save the file or even "save as." I'm in the middle of editing my senior thesis and do not want this problem anymore. Can anyone help me fix this. Do I need to get permission or ownership of my entire hard drive somwhow as well? Should I try to copy and paste the files and delete the originals? I believe it is effecting my entire My Documents folder at this point. Any advice would be great. Thanks.
