Unable to obtain command headers.

[SebSpiers]

Hi Guys,

So I've got an issue with the Create Shortcut function, it seems to be throwing up a runtime error.

"Unable to obtain command headers. Please rebuild your project."

My question simply is, what are command headers? and how do I resolve this issue?

The Create Shortcut I'm trying to do is very simple:

Code: Select all

Create Shortcut C:\Users\Public\Desktop\Software Name to C:\Program Files (x86)\Software Vendor\Software Name\Software.exe, Pin to Start Menu

Any ideas?

Dear SebSpiers,

for what I see your Create Shortcut statement is not correct.
I suggest you to have a look at the "Shortcuts sample" from;

Looking at the example the only differences that I can see are that:

1. I'm not trying to Run as Administrator
2. I am manually specifying the location in which I would like the shortcut placed

This should work, no?

I have reviewed the documentation here: https://www.installaware.com/FlashHelp/ ... ortcut.htm

I am only specifying values for:

1. Shortcut to File - which I can confirm is correct, I can launch the application using the value in the Run dialog box.
2. Link Name - this is just a text value, so should not have any impact at all?
3. Link Location - This is set to "C:\Users\Public\Desktop" - which is for all users.

Windows Size set to Normal.
Everything else is unchecked and/or empty.

Any thoughts?

Dear SebSpiers,

for sure there is an error somewhere with the approach you used...however, without having your exact code it's quite difficult to say where this could be.

As I said previously, I suggest you to replicate in your code how the shortcut gets created by the sample. Of course, you don't need to specify any "Run as Administrator" option.

I solved this using a compressed vbs script to create the shortcut.

vbscript (mkshortcut.vbs)

Code: Select all

set WshShell = WScript.CreateObject("WScript.Shell" )
set oShellLink = WshShell.CreateShortcut(Wscript.Arguments.Named("shortcut") & ".lnk")
oShellLink.TargetPath = Wscript.Arguments.Named("target")
oShellLink.WindowStyle = 1
oShellLink.Save

Used like this:

Code: Select all

Extract 7Zip Archive $SUPPORTDIR$\mkshortcut.zip into folder C:\TempRun Program C:\Temp\mkshortcut.vbs /target:"C:\Program Files (x86)\XXXXXXXXXXX\XXXXXXXXXXX.exe" /shortcut:"XXXXXXXXXXX" (WAIT)
Run Program cmd /c copy "C:\Temp\XXXXXXXXXXX.lnk" "C:\Users\Public\Desktop" /y (WAIT)
