In my test environment and am trying to install 10.2.400. This is what happens when deploying the App Server. 10.2.300 did not give me this error so I am not fir sure what this is saying.

Hi @Will79, Are you deploying your AppServer with the most basic vanilla options first (don’t check Reporting Services or any of the Extensions) and are you still getting this error message? Do you know how to clean-up all of the files that were created and try to re-Deploy? ---

Yes, I tried that and still got the same issues. Then I exited, restarted the server, and tried again. This time it worked. SO IDK!!! 🤔🤔 ---

Went to re-test and re-install 10.2.400 and got the same error. This time, nothing is working to get pas this error. ---

@hmwillett @ERPSysAdmin @aidacra Any other ideas? I have disabled the firewall, restarted, and still getting the error. ---

I think at this point, if I were in your position, I would completely remove the app server from the admin console and all of the references and folders in IIS and drives and then create a brand new one. ---

This isn’t even working? (What you did the last time to get it working. 😉 ) > [@Will79](#): > > Then I exited, restarted the server, and tried again. This time it worked. SO IDK!!! 🤔🤔 When you retested the install of 10.2.400 did you do it on a new VM or server? Or did you just uninstall 10.2.400 and re-install it? If you did an uninstall and reinstall I think maybe you aren’t cleaning up all of the files that need to be cleaned up with an uninstall…? I could give you a list of items that I usually clean-up when I do an uninstall. ---

What I did was take a copy of my live DB and restored it to the Test environment. Then I installed 102400. I have removed everything I can think of in inetpub, Epicor folder, and IIS. If there is something I am missing, pleas e let me know. ---

Check this thread for ideas. Note the .Net 4.7.2 installation comments. > [@10.2.400 New Install Gotcha's](https://www.epiusers.help/t/10-2-400-new-install-gotchas/55806): > > When installing the RL10.2.400 iso and once everything is installed and you select the checkbox to launch the admin and… nothing happens. This is most likely because the server does not have .NET 4.7.2 installed but the Epicor installer never checks for this prerequisite to notify this is required and not installed on the machine. Brett
