LabVIEW 8.5.1 project file cannot be opened by other users.

In LabVIEW 8.5.1 I created a project file, but other users with admin rights can not open it.  How do I fix this?

Hi Boeing,

What operating system are you using?  If you are using Vista, check out the following links.  They have some good information on using multiple user accounts.

If you are using XP, check out the following page to ensure that file permissions are set correctly.

What exactly happens when they try to open it? Error messages?

I am using Windows XP, Service Pack 2 on a PXI chassis purchased from NI.  The error message displayed when another user (with admin rights) tries to open the project is "Project or Library file cannot be opened".  Normally in Windows XP, when a directory is right-clicked, there are four tabs, General, Sharing, Security and Customize.  For some reason, the Security tab is missing on this computer.

Hey Boeing,

I would take a look at the following external link: Use access control to restrict who can use your files.  Down at the bottom of the page there is a section on showing the Security tab.  Give that a try and see if you can then grant permissions to the other user accounts.

Using the advice provided, I was able to add the Security tab.  Then I went to Security-Advanced-Permissions and gave the Administrators group full control permissions.  That was not sufficient to allow other administrators access to the project file.  Then I changed ownership of the directory and its contents to the Administrators group (Security-Advanced-Owner).  Then everything is ok.  The problem is resolved.  Thanks to those who helped!

I could open any of the vi's in the project no problem, just not the project itself.


I got the error message "project or library file cannot be opened"


I right clicked on the project file and went to security. I found all administrators had access. I am an administrator but I was still blocked from opening the project.

I added my name username specifically to allow access and then I was able to open the project.
