Re: VC++ Runtime error 1603 unable to install update

A couple of more things to try. 

Solution #1 - Change the name of the following folder

1. Rename the following folder:

   C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18 
   to
   C:\ProgramData\Microsoft\Crypto\RSA\S-1-5-18_BAK
   
   
   
   Solution #3 - Remove the updates triggering the errors

   1. Go to Control Panel > Uninstall a program (or Programs and Features).

   2. In the left menu, click View installed updates.

   3. In the search box at the top-right, search for KB2918614.

      If you find it, uninstall it.

   4. Do another search for KB3072630, KB3000988 and KB3008627.

      If you find them, uninstall them as well.

   5. Reboot the computer and try installing the  software again.

   
   
   Its a tricky one, good job I like puzzles.  its not error 1603, its the 997 i/O operation one.  That stops Origin installing the VC file.  That one is caused by a temporary profile being used to install, or something like that.  Which probably means your current user profile is corrupt or doesnt have sufficient rights, or somewhere along the line the file ownership is screwed.  The other possibility is to create a new user on the machine with administrator rights and a password.  Log in as that user and do the update. 
   
   
   Let me know how how it goes.
