Hello,

I need to run a MSI-file (Microsoft Installer) from my application and I want my application to wait until the installation has been finished.

Waitrun() and Winexec() cannot be used since they don't work with a MSI-file.

So I try to use ShellExecute()

This is the code :

Code: Select all  Expand view

ShellExecute(,"Open","MSXML.MSI",,,3)
SYSWAIT(5)
DO WHILE .T.
   hFile := FOPEN("MSXML"+IF(IsWin7(),"6","4")+".MSI",FO_READWRITE + FO_EXCLUSIVE)
   IF FERROR() <> 0
      SYSREFRESH()
      SLEEP(1)
      LOOP
   ENDIF
   FCLOSE(hFile)
   EXIT
   SYSREFRESH()
ENDDO

Unfortunately, my application doesn't wait until the installation has been finished.

How can I solve this problem?

Thanks you.

Are you sure? I never tried for myself but I can't see why they shouldn't work.

Enrico,

I'm quite sure indeed.

I tried both like this

Code: Select all  Expand view

WinExec("MSXML.MSI",1)

WaitRun("MSXML.MSI",2)

and nothing happens.

Thanks.

Michel

You need to indicate the whole path

waitrun("c:\.....\msxml.msi")

Richard,

I tried them out with the full path, but no luck. The result is exactly the same.

But now I check which message was returned.

Waitrun() returns -1
WinExec() return 11 which means that the executable file was invalid.

But if I launch the MSI-file manually, everything goes fine.

Thanks anyway.

I tryed this with no problems:

ShellExecute(,"Open","MSXML.MSI",,,3)
SYSWAIT(5)
DO WHILE .T.
hFile := FOPEN("MSXML.MSI",FO_READWRITE + FO_EXCLUSIVE) // !!!
IF FERROR() <> 0
SYSREFRESH()
SLEEP(1)
LOOP
ENDIF
FCLOSE(hFile)
EXIT
SYSREFRESH()
ENDDO

Thanks a lot for your reply.

I know that this is working. But I need my application to wait until the installation has been finished. And that doesn't happen. My application just goes on.

Michel,

Try this:

waitrun( "msiexec.exe c:\temp\msxml.msi /I /QN")

James,

Thank you very much for your help.

This code did its job :

Code: Select all  Expand view

WaitRun("msiexec.exe /i c:\temp\msxml.msi")

Thank you so much.
