Unable to open NT 8 (64 bit)

[theworldtocome4444]

I recently installed NT 8 (latest version) on a new computer and was able to run it just fine. But then I decided to uninstall but then reinstall it and now when I try to run the program I get an error message.

Unable to connect to DB. Could not load file or assembly 'System.EnterpriseServices.Wrapper.dll' or one of its dependencies. Error performing inpage operation. (Exception from HRESULT: 0x800703E7)



I AM able to run NT 32bit just FYI



I have WIndows 10 64bit

Hello theworldtocome4444,

Thank you for your post.

Please reboot your PC. Then try again to reinstall NinjaTrader.

The error code:0x800703E7 generally indicates that the update or reinstall did not install properly.

I still have the same error after a reboot of my computer. The very first installation on my computer worked, only once I uninstalled and reinstalled have I gotten this message now every time I try to open the 64 bit version. The 32 bit version works fine

I followed these instructions exactly and still get the same original error I did in my first post when trying to open the 64 bit version
