You may have already tested having two simultaneous versions of Office installed on your PC, but I had not. When I signed up for Office 365 I downloaded and installed Office 2013 not realizing Office 2007 would remain intact. I read somewhere it was not recommended to have both versions installed on the same PC. With that said, I have not run into any real issues. I have used Access 2013 to open most of my 2007 files without issue and made changes to the same file in both 2007 and 2013 without issue.
The same has not been true for MS Word and Excel files. Though most of the files I have tested with 2013 opened successfully; some refuse to open at all. In Word, it has been files with tables (and not all files with tables). I have no idea what is causing some Excel files to not open. If I have a file open in 2013 and attempt to open one of those “stubborn” files in either Excel or Word they both freeze. I am forced to completely close the program and cannot save any changes made to the other open files.
Is this happening because both 2007 and 2013 programs are installed simultaneously or will those files never open in 2013? I don’t know. I guess I will find out when I uninstall 2007. Of course, this makes me a little nervous uninstalling Office 2007.
Making sure I save a new file on my PC and not the SharePoint server has taken some adjustment as well.
I am trying to find some time to learn a couple of programming languages and become more skilled at sql because it greatly affects how sophisticated any future web apps can be. However, when you consider my lack of skills, I have not experienced any real issues creating web apps or dealing in the SharePoint environment. One has to give Microsoft kudos; if I can do it anyone can.
