Open External program with vba

[aspen]

Hi guys
I am trying to open an a file with an external application.

Shell Chr(34) & "C:\Windows\System32\mspaint.exe" & Chr(34) & " " & _
Chr(34) & strFilePath & Chr(34), 1

I am using the above code to open paint. and when I change the App path to open another program its not working. Invalid procedure or call argument. The program is. AdobePhotoshopExpress
Its a free app I downloaded from store windows 8.1
and here is the path

	
	
Shell Chr(34) & "C:\Program Files\WindowsApps\AdobeSystemsIncorporated.AdobePhotoshopExpress_1.2.0.20_x64__ynb6jyjzte8ga\psexpress.exe" & Chr(34) & " " & _
Chr(34) & strFilePath & Chr(34), 1

Both paths I copied from task manager.
Any help would be apreciated
Can some one please help me solve this?
Thank you

I would first test it in the Run window and then transfer what worked there to VBA. Considering the error, I would guess the app is having trouble finding the path to your file. So I would first test.

C:\Program Files\WindowsApps\AdobeSystemsIncorporated.AdobePhotoshopExpress_1.2.0.20_x64__ynb6jyjzte8ga\psexpress.exe

After I was successful there I would then move to

C:\Program Files\WindowsApps\AdobeSystemsIncorporated.AdobePhotoshopExpress_1.2.0.20_x64__ynb6jyjzte8ga\psexpress.exe "C:\FolderName\FileName.extension"

I often have trouble using Shell and then have to use ShellExecute - more complicated but seems to always work. I don't have an example for you but I am sure you can google it.
