Dear great experts:

I run the following script:
cmd /c powershell.exe -WindowStyle Hidden -NonInteractive -command {$hklm = "HKEY_LOCAL_MACHINE" ;$key = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Wireless-101_is1" ;$value = "InstallLocation" ;$a=([Microsoft.Win32.Registry]::GetValue("$hklm\$key",$value,$null) + 'bin\App.exe') ;& $a}。
The function of this script is to query the registry and then run the application in the installation path.

Now the problem is: If it is run in PowerShell under Win7, after entering the PowerShell interface, running this script is OK, and the application can be called correctly.
But: If it is run in cmd in Win7, entering the normal command line interface, running this script has problems.

If in the cmd interface, run the cmd /c powershell command once first, and then run this script, there is no problem.

Hope that great experts can give advice!

Which expert has research on this thing?

Or other methods to achieve the following functions can also be used:

Need to obtain the application installation path by querying the registry in the CMD interface, and then start this application. For example: cmd /c powershell.exe -command “& {…………}”
