Open Task Manager and on the Processes tab sort by Image Name. Click Show processes from all users. Look for the file msiexec.exe. You should find two instances of this file running. This is the cause of the problem. Select one of the files and click End Process. Repeat for the other. Then try your download. One instance of msiexec.exe will open. The download will be successful. You will probably find that two instances of the file will start each time you turn on your computer and that you will have to repeat these steps for any more downloads. Not perfect since it is not a cure but a satisfactory work around.
have a nice day.
