Thanks for your great work, UltraViewer really works fantastic with Windows. Is there a possibility that it also works with Ubuntu?

That check box to run Ultraviewer with Windows (10) does not appear to do anything regardless if I change the setting running Ultraviewer as admin.

Any idea's?

I really appreciate very much for allowing us to us Ultraviewer for free. I’m using this application to provide remote support for internal systems in our Institute. Is there a way to keep a record of IDs and users so that I can easily connect machines?

Best Wishes,

I tried to control a computer what shows a presentation-screen. That means, after restart UltraViewer should open automatically from the logon-screen. It did not by setting in Ultraviewer. I set to task-schedduler and autostart (in the registry) but it did not start automatically. Only by logon with mstsc and open UltraViewer manually I could establish a connection. When I would use only mstsc, the screen would left with locked windows, but it should show the ppt or any other open window, like after disconnecting Teamviewer or Ultraviewer but without logout.

No ID on W10 64b
Ultraviewer works well on W7, but on W10 it cannot get an ID. We observe with Currports that it tries to connect to several SYN addresses on port 443 but without success. Its Competitor T .... r obtains an ID without problem.
config W10 64b no antivirus or firewall

Probably the same problem here as "Yannick 3/30/2020 8:51:18" has described. When the user is logged, Ultraviewer is running and the ID is obtained - I can access from remote without problems. When user has logged off (or is automatically logged off after certain period of inactivity), the ultraviewer seems to be running but there is no ID on the "switch user" screen. Although I can see (using local network tightvnc) that there's a Ultraview window in right top corner with hidden password but missing ID!!! In this state any atempt to remote access ends with error message "Cannot connect. Your partner is not running UV or is not connected to internet now).

Win10 64-bit

Thanks for looking into matter.

Ultraviewer does NOT allow for UPPER CASE LETTERS?

This is a huge issue for me because I use UPPER CASE letters to access or login to my PC and once I am logged in and try to access certain password protected websites that have UPPER CASE letters I am unable to access those sites.

CAN YOU PLEASE EXPLAIN WHY UPPER CASE LETTERS DO NOT WORK? I have tried using SHIFT and also have tried CAPS LOCK and nothing I do works I am about to uninstall the program if this cannot be resolved since too many of my secure sites user UPPER & lower CASE letters and if Ultraviewer does NOT support UPPER CASE letters it will never work for me. Please share a solution to this problem!

A scam artist locked up my computer with Windows 7. I cannot get passed the message “Windows cannot repair this computer automatically.” I am using my iPhone for the message. Thank you.
