Usually that error comes up if the Command Prompt can't find what you are trying to run. If you know where Citrix installed itself to (default install location will be "C:\Program Files\Citrix\ICA Client" or "C:\Program Files (x86)\Citrix\ICA Client" if on 64-bit Windows), you can change the directory your Command Prompt is working in by typing the location of "CitrixWorkspaceApp.exe", but put "cd\" in place of the drive letter it is installed in.D'oh! thank you for catching that.
I really hoped that was it, so I tried again. Still no dice.
C:\Users\TEMP.DESKTOP-R9HJQ15>CitrixWorkspaceApp.exe DDLOCAL=ReceiverInside,ICA_Client,AM,SELFSERVICE,DesktopViewer,Flash,Vd3d,WebHelper,BrowserEngine
'CitrixWorkspaceApp.exe' is not recognized as an internal or external command,
operable program or batch file.
Any help would be appreciated. Or maybe a idea as to why it wont work.
