Wordup Bryan, the main error here is nwith your registry files, you need to change some of the settings in the registry. Some of these are the registry keys.

Open the registry and change the keys to the following;



On machines with 64-bit Operation System



Restart the software and it should work

Hello Bryan,

That error you are getting is related to issues with registry entries, and therefore to resolve it you will need to do the following:

Locate the following registry entry on your computer: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesmisiserverWOW64. Check if it has been set to 1 on the machine that is having issues.  You will need to change it to 0 and after that retry the installation.

Other workarounds that you will need to try are the following:

  • Try performing a system restore just in case you might have made some changes on your computer that are causing the issues.
  • Another thing you will need to do is check if the security applications that you have on your computer may be blocking the installation.

Hope this helps.
