Use of drive letters A:or B: break Labview activation.

[Peter_S]

Hi,

mapping  the drive letter A: or B: to extra hard disk volumes break the Labview activation.

In Activation FAQ is written:

Q: On What Is My Computer ID Based?
A: Your computer ID is based on the MAC address of your Ethernet adapter. In some cases, your computer ID is based on the disk volume serial number.

Ho can I force the license manager to use the serial number of the system volume C: ?  Not  the hard disk with the lowest letter.

Or deactive this check?

A working solution is to use the volume serial number of C: also for B: by sysinternals VolumeID.  But normally they should  be unique.

So do you have you A and B drives as hard disks? What difference does it make? I always assumed that the license manager used the ID of the disk where LabVIEW was installed.

Yes, an extra partition of a large SSD for some VM's to exclude it from an image backup.

And also if I change the letter of a 2nd data disk to A:.

>What difference does it make?

A new Computer ID of license manager.Setting the volume serial number of C: also to B: keep the Computer ID.

It  seams that it take the ID of the hard disk volume with the lowest letter.

It's not surprising that a drive mapped to "A:" or "B:" will break LabVIEW activation.  In fact, I'm surprised it doesn't break more things, including things unrelated to LabVIEW.  "A:" and "B:" are traditionally reserved for floppy disk drives and many Windows applications won't even consider "A:" or "B:" as a legitimate hard drive letter.  Ever wonder why the default system drive is "C:" and not "A:" or "B:"?  Now you know why.
