Web Deployment Troubleshooting

If you experience a delay on the first click of major functions within the EMS Desktop Client, there are a couple of solutions. One approach is to leave EMS running all day, so you only experience the first click delay once. Another approach, that is a bit more involved, is to run a function within .NET called NGen. This function pre-compiles .NET applications to make them load significantly faster and eliminate first-click delays.

Run NGen 

You must have installed EMS and you must have administrative privileges to perform the following steps.

1. Open a command prompt as an administrator:

   1. Press the Windows key.

   2. Type cmd in the search bar.

   3. Position the cursor over Command Prompt, right click, and select Run as administrator.

2. At the C:> prompt, go to the directory the EMS is installed.

   If you have conventionally installed EMS, then it's typically at the following location:

   cd \program files (x86)\EMS

   If you're using the web deployment option to install EMS, you can find EMS at the following location:

   cd %appdata%\EMS2016\EMS

3. Press Enter and you might see one of the following where [user name] is your Windows user name:

   C:\Program Files (x86)\EMS>

   C:\Users\[user name]\AppData\Roaming\EMS2016\EMS>

4. Type the following:

   \windows\microsoft.net\framework64\v4.0.30319\ngen install ems.exe

5. Press Enter and wait until the process finishes.

   It takes about 5 minutes. Ignore any error messages.

6. When the installation finishes, close the command prompt and run EMS.

If you install a new or updated version of the Desktop Client, you must run NGen again if you want to eliminate the first click delay.
