You are probably missing the SNMP settings. Right click on start button and go to settings. Select apps and then click on additional apps. Click add a feature and select SNMP and WMI SNMP. Install both, then reinstall Emanager.
PhoneGuy827 - Thanks for the suggestions. While it did not fix my V5.20C01 issue directly it did help find the solution after working on this all day and attempting to loading V5.20BW10 on there other computers (I was able to get 2 out of three loaded with the new version). And becasue of all the other issue I discovered the solution for the "Please Wait" on my V5.20C01. So all is working now.
Here is the summary of the fix:
If anyone is using the PDF Instructions to install Network eManager V5.20BW10 I recommend you add these steps:
1) Check in Services to verify that the SQL services are running. If not ensure they are set to automatic and start. Verify they are still running, if not reboot.
2) Force eManger to open in IE 11 mode.
Open your eManger application. Click the 3 dot menu in upper right corner of Edge. Select Reload in Internet Explore mode.
After loaded, change how the page opens in the future by toggling on both "Open this page in compatibility View" and "Open this page in Internet Explorer mode the next time".
Or Open Edge and click 3 dot menu in upper right corner. Open Settings, then click "Default browser in the left menu. Under Make legacy site work in Microsoft Edge select add then add "http://localhost/eManager/login.aspx " as the site to used IE mode
Now to figure out how to install/program the Caller ID card.
I will post the long details next.
