project or library file cannot be opened

[Bernadette]

I need to make changes to an old project that was done a fews years ago.  Using labview 8.6, I tried to open the project file and I get a dialog box with the following statement:  "project or library file cannot be opened".  There's no other information, so I don't know how to address the problem.

Hi,

What LabVIEW version are you using to open the project created in LabVIEW 8.6? Because as you can see at the following link, if your project was created in LabVIEW 8.6, you should be able to open it in LabVIEW 8.6, 2009, 2010,2011 and 2012.

I dont thinks it is version problem becasue if it is so it will say that.

Can you attach that VI ?

There's usually a quick description of why it can't be opened.  It could be corrupted.  It could have already been saved in a newer version of LabVIEW.  Post the library and we can give better advice.

You mean to say database file is corrupted ?

No, the project file.  There is no database involved here.

Might possible.

I'm getting the same error but my circumstances are different.

Due to a system dump I've had to move my LabVIEW environment to a brand new computer.  The OS changed from 32-bit Windows 7 to 64-bit Windows 10 and LabVIEW went from 2015 to 2016.  I'm not having any trouble opening up VIs or LLBs, however, project files will not open.

I've gone through the Windows 10 files system and made sure all the permissions/access are correct.  I've been granted sys admin privileges (yeah!) I shouldn't have any problems.

My projects are large and complex, so I REALLY don't want rebuild the project file from scratch.

Any suggestions?

Have you tried a mass recompile of your project?

[faustina]

How would I mass compile the project since I can't open the project file?
