Long start TestExecute from script

I'm running TestExecute from the scripts:

Run.bat

taskkill /im TestExecute.exe /f
cscript RunTEGroup.vbs

RunTEGroup.vbs

WScript.Echo FormatDateTime(Time) & "[Info]: CreateObject TestExecute 11"
Set tc = CreateObject("TestExecute.TestExecuteApplication.11")

Set tci = tc.Integration
tc.Visible = False
tci.OpenProjectSuite(projectSuite)

WScript.Echo FormatDateTime(Time) & "[Info]: The project suite was opened."

After the launch this script from any virtual machines, the time between events "CreateObject TestExecute 11" and "The project suite was opened." in the region of 10 minutes.

How I can find out why there is such a long start?
