Inno Setup launching bat file

Question

I'm using Inno Setup to run pnputil.exe utility. Here is my code:

Exec(ExpandConstant('{app}') + '\driver_install.bat','"'+'pnputil'+'"','',SW_SHOW,ewWaitUntilTerminated,ResultCode);

The driver_install.bat contains the following:

echo off
echo "PLEASE WAIT WHILE DRIVERS WILL BE INSTALLED"
%~1
echo "IT MAY TAKE 5-10 min"
PAUSE

I'm passing the parameter "pnputil" to the bat file. I'm using bat file because i want user to see the output. The problem is that on windows 8 i get

'pnputil' is not recognized as an internal or external command,
 operable program or batch file.

When i change the pnputil to cmd the output is fine. The administrator rights are not the cause here because pnputil can be launched from console without administrator rights.

Answer 1

您必须改为使用%windir%\\sysnative\\pnputil.exe调用pnputil。
