Posts: 6 		Hello. Firstly I just wanted to tell you, your product is AMAZING, keep up the great work guys. I have used Visionapp and others, your product beats them all.

I am getting a new error with the recent build of RDM 5.7.3.0. When I try to open a Microsoft RDP session in a TAB (Display Embedded) it says "Unable to find Microsoft Remote Desktop Client". When I choose to open it in a new window (Display External) it works fine. Any idea what is happening? I confirmed the path to mstsc.exe is correct. This is not happening on my other machine which is running RDM 5.5.1.0, on that machine I am able to open connections to the same clients in embedded tabs. This is happening on two of my host machines, both running 5.7.3.0. I am trying to connect to Windows 2003 and Windows 2008 clients, so I don't think the version of the client RDP is an issue here.

Thanks.

What OS do you use ? Can you check in the application log if you see something, it's in the menu Help. Usually it's because the application is unable to find the ActiveX, but it's not normal since it was working before.

Posts: 6 		Hi. I am getting this error on 2 of my machines, one is Windows Server 2008 R2 and one is Windows XP.

I have 5.5.1.0 running on my Vista laptop without any problems, the embedded mode works like a charm.

So on the 5.7.3.0 version the RDP session works fine in full screen but the error only occurs in the "embedded" mode.

Is there an application log for RDM? The event logs dont have any errors in there.

Thanks.

Thank you for the log, I added some logging to this special version, can you clear your log and try it ?

Posts: 1349 		Hi,
I really don't understand, the application is unable to find the RDP Active X, but you said that it's work fine with a previous version (5.5) ? Is the Window XP that does this error ? Can you try to apply the RDP 6.1 update?

Posts: 6 		The strange thing is that full screen works perfectly with no problem. Sure I can try that. But like I said, this exact same thing is happening on a totally different machine which is running Windows Server 2008 which should have the newest RDP client.

Posts: 6 		Upgrading the RDP client to 6.1 worked, thanks!



For some reason I was thinking it was not working on a Windows 2008 machine but it is actually Windows 2003 I was having trouble with (I'm connecting to Windows 2008 servers). So upgrade the RDP client on this machine fixed the problem, too.




Thanks for your help.
