MAX does not display any serial ports

[billko]

What are the specific software versions of MAX and LabVIEW are specifically installed on the failing ones?  We can only talk about generalities unless we can get specific.

LabVIEW Run-Time 2012 f1 and earlier

Measurement & Automation Explorer 4.7.1

NI-DAQmx ... 9.2.2

NI-VISA  5.0.2

NI-VISA  runtime 5.0.2

Hello, 

Please ensure that your motherboard drivers and BIOS are updated to their most recent versions, and try to install the most recent version of NI-VISA, 5.3 from the following link.

OK.  Thansk for all the help.

Here's what worked:

a) uninstall ALL LabVIEW stuff.

b) install new MAX

c) inslall new VISA

d) install RUN-TIME (for the specivic version of LabVIEW from which the exe was created.)

Just out of random curiosity.  (Well not entierly random)

Did you have a PXIe chassis connected via MXI?  For some stange reason when I power cycle my PXIe 1078 MAX gets angry, looses my com ports, looses my software, looses some PXI devices.... Until I reboot with the PXIe 1078 powered on first.

Jeff -

No.  Just PXI slot based cards.

Might have been multiple causes. 

Don't care at this point, just being a little more attentive to versions of software to install.
