Getting path of exe

[Munna232]

Hello all,

I need small help. Please help me.

Currently I’m opening other “*.exe” with LabVIEW (System Exec.vi).

I’m passing exe path to System Exec.vi & It is working well.

The problem is, exe path is different in some of the user’s PC so, I’m getting error.

I want to find the path of exe from user’s PC before sending to System Exec.vi. Is there is any better idea for this?

I think, checking complete PC may take long time.

I have one more doubt, if I’m running same exe with “Run” command (without complete path), It is working (Example: AcroRd32.exe).

But, It is not working if I’m running same exe with System Exec.vi/Batch file.

I want to know how “Run” command is recognizing this exe path & how to extract the location.

Also keep in mind the environmental variable thing. Is the path of the exe set in the PC?

Another issue can be this:

But usually I just distribute the required exe simply copying it to the Application Directory. Using the Application Directory path function in LV, I call the system exec.

Dear Blokk,

Thanks for your reply.

Required exe is present in User’s PC but path is different from one user to other (C:\ or D:\).

I can’t copy required exe to LabVIEW Application Directory (Due to copyrights issue).

Did the above link help?

I tried but it is not working.

I'm getting below error:

'C:\Windows\Sysnative\AcroRd32.exe' is not recognized as an internal or external command,
operable program or batch file.

Is it a x64 OS, and AcrobatReader installed?

The link mentioned by Blokk solves problems if the executable is expected to be in the Windows system directory.

AcroRd32.exe is not located in the Windows system directory, but in an Adobe directory. For example on my PC C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe, so the path C:\Windows\Sysnative\AcroRd32.exe doesn't exist at all.

Take a look at HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App Paths in regedit.exe

I guess this is the place where the Run command finds executable files, if they reside in directories not included in the environment PATH variable.

If the location of the file is in the PATH, then it can be started via System Exec.vi. Otherwise you may look in the App Paths for it.

Hi Munna,

when AcroRead is used as default PDF viewer you can start it by simply calling a PDF file of your own (and in a path controlled by you)…
