Guys Im not sure if this is the correct place to post for help but here it goes.

I had FSX installed on my windows 7 computer and worked just fine. Well time went by and I upgraded my windows 7 to a windows 8 and decided to do a reinstall of the game. Well the uninstall worked fine and when I reinstalled the game it kept telling me that my product key wasn't valid. I searched around and found posts where it told me to do a fresh reinstall of the game so I uninstalled the game once again but this time the game wouldn't uninstall from my computer. I tried several options and nothing would work. I then searched around and found posts to delete everything manually in which I did and did a registry cleaner. Now I cant install the game again and keep getting a message that reads

 

1628: failed to complete installation

 

Anyone have any suggestions. Im confused of whats going on

I like the following guide for uninstalling/reinstalling FSX - http://support.precisionmanuals.com/KB/a87/how-to-uninstall-and-reinstall-fsx.aspx.  Shows you where all the hidden files are located so you can get rid of them as they need to be removed before reinstalling.  I would add to the guide that you should run a freeware registry cleaner like CCleaner before reinstalling.

 

Before doing that you can also try the following fix - http://support.microsoft.com/kb/910816.  Unfortunately it does not work for everyone and, if it doesn't for you, then you will have to reinstall FSX as above. 

 

Best regards,
