Hi, I am using tcc/le 9.02.152 and I cannot understand how to use start /runas command. Here's what I want to do start /runas "lamia domestica" mypassword c:\test\test.exe Unfortunatelly I don't remember the exact error message but it was something about "Cannot find user name." I tried to specify my computer as logon domain: start /runas "lamia domestica@uriel" mypassword c:\test\test.exe but got the same error. The problem is that the user name has a space. When I try with a user name without a space, it works fine.
