Oh god thank you, finally a solution that worked!
I've been struggling for several days with all kinds of solutions, from both this forum and others. I'm running a windows 7, 64 bit system from dell.
Just another possibility for others that may find this post.
I have seen IE9 affect some installs. Sometimes this can cause a blank register screen. Rolling back to IE8 can help, but it is not always a simple process.
1.) Log in to Windows and go to the Control Panel.
2.) Access Programs and Features option
3.) Click “Turn Windows features on or off”.
4.) Uncheck the Internet Explorer 9 box
5.) Click “OK” and the system will process.
6.) After this completes, shut the machine down completely and restart.
7.) When windows boots click the Windows Start button
8.) Access the Run box and inside, type CMD.exe but do not press [Enter].
9.) Move your cursor over the CMD.exe icon above and right-click
10.) Click Run as an Administrator
11.) In this window copy and right-click paste the following text:
FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-*9.*.mum /c "cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart"
12.) Press Enter and the process will run. You may get errors. Accept them.
13.) After this completes (may take a few minutes and look like nothing is happening- wait!) run the same command again. (2x total)
14.) After this is through, go to the Control Panel.
15.) Access Programs and Features option
16.) Click "Turn Windows features on or off"
17.) Internet Explorer 8 should be present, make sure it is checked
18.) Close the window and try to run and activate the software
