Error when running measurement explorer; corrupt installation on Windows XP

[rumford]

When I launch measurement explorer in Windows XP, I get an error stating: Unable to open connection to server. Config.mxs file or installation corrupt. Please delete config.mxs file in the same directory as NIMax.exe,please delete file, reinstall and then check ni.com if problem not fixed.

I have tried deleting the config.mxs file and have reinstalled NIDAQ 6.9.3. Whenever I try to install NIDAQ 6.9.3, I get an error message 1605 relating to the installation of NI-Pal 15.6f0. I continued the installation when prompted. Could this be corrupting measurement explorer?

Hello;

At this point, the best way to go about that is to completely uninstall every National Instruments Software you have there, reboot the machine and clean up the registry window.

To clean up the registry window, go to Start->Run and type regedit. That will take you to the registry window. Once there, go to HKEY_LOCAL_MACHINE->Software and delete the National Instruments folder from there.

After all that done, install only NI-DAQ 6.9.3 and everything should gfo back to normal.

Hope this helps.

I followed the directions to clean up registry. (Even though I was logged in as administrator, I had to change permissions on the National Instruments registry key to delete the key). I then reinstalled NI-DAQ6.9.3; but I still get the same error when I run measurment explorer. Any other thoughts?

Thanks,
Rob

Rumford, you are not alone. I have the exact same trouble, also on WindowsXP. I've deleted the config.mxs file, same problem. Uninstalled, rebooted, reinstalled, rebooted, same problem. Uninstalled, rebooted, cleared the registry, rebooted, reinstalled, rebooted, same problem.

NI, any ideas? I love the ideas of this DAQPad, but so far it's cost quite a bit of time.

I figured out how to get MAX to install properly under WinXP. My clue came when I had to change permissions in the registry before I could delete the registry settings when reinstalling. MAX must have to write something to the registry when it first starts up, and I noticed the whole registry tree had no permissions even after the re-install. After going to the national instruments top level registry entry, I changed the permissions to full control for administrator. Then click on Advanced and click replace permission entries for all child objects. After this, I could start up MAX with no problems. I would suggest backing up your system before you try this. I don't know if this is something NI can fix with the install or if this is a WinXP problem to prevent
having to do all this in the future.
