Visual Studio Test Manager 2013 does not record actions

We have noticed that Visual Studio Test Manager 2013 behaves differently on some of the machines. More precisely, it does not record actions on some of the machines, while it works perfectly fine on the other machine while running the same test plan under the same test settings. All machines were running Windows 7 with the same version of Visual Studio installed. User tried rebooting the machine, clearing cache, you know the usual stuff. Nothing helped. This is where I stepped in. J

After a bit of digging, I have noticed that Visual Studio Test Manager 2013 is running fine on 32-bit installs of Windows 7. Visual Studio Test Manager was also running fine when users were running 32-bit of Internet Explorer instead of 64-bit version. Then, I have remembered that Visual Studio Test Manager 2013 does not support 64-bit version of Internet Explorer for recording and playback (see http://msdn.microsoft.com/en-ca/library/dd380742.aspx for more info.) So, as long as users are using 32-bit version of Internet Explorer (C:\Program Files (x86)\Internet Explorer\iexplore.exe) instead of 64-bit version of Internet Explorer (C:\Program Files\Internet Explorer\iexplore.exe) everything is working as it should. Problem solved. Sort of.
