So I just downloaded and installed GroupDocs.Total Free Apps for Windows 21.6 on my Windows 7 32bit. However, it says that the version of the app isn’t compatible with my Windows and I need to choose the right one (x86/x64) whenever I try to run the app although there’s only one file available to download. Does the version only work on 64bit, so I need to install any of the earlier versions? If so, which one?
