Labview 8.0.1 will not install

[ambe]

After uninstalling Labview 8.0.1 due to other problems, I have reloaded 8.0 (along with the device drivers from the latest Developer Suite - May 2006) without problem, but when I try to install the 8.0.1 update, the installer says it is already installed.  When checking the version reference when Labview is running, the "about" box says that the version is 8.0.  I have also checked the Windows (XP Pro) registry and it states the version as 8.0.  Is there some other "install" file or something that needs to be deleted?  I also have 7.0 & 7.1 installed on the same computer - could that be related?  Has anyone seen this?  Any ideas on how to install the 8.0.1 Update?

ambe,

There are some things left behind on your computer when you uninstall LabVIEW, one of them being the LabVIEW directory which has the LabVIEW.ini inside of it. Try renaming the LabVIEW.ini to something else and see if you still have the problem.

Also, you can verify the version of the run-time engine installed by checking the version number of lvrt.dll under ..\National Instruments\Shared\LabVIEW Run-Time\8.0\. It should be 8.0.1.xxxxx if LabVIEW 8.0.1 Run-Time Engine is installed.

Post to let us know what you find.

Chris:

Thanks for the feedback. 

I had tried deleting the Labview.ini file before I posted the message. 

I checked the run time version as you suggested and it does say that it is version 8.0.1.4000, so that does seem to be loaded.

Labview.exe however shows up as version 8.0.0.4005.

Any other ideas?  Should I uninstall, then delete the Labview 8.0 folder before reinstalling?  I don't want to do this too many times as it takes a vvvvvvveeeeerrrrrrrrryyyyyyy long time to do this!!

The 8.0.1 installers still seem to be registered with the operating system even though you do not have the 8.0.1 files on the system. The following command line will force the reinstall of the sections that of the installer that are already registered with the system.


  setup.exe /reinstall /log c:\lv801install.log

This command line will also create a log file at "c:\lv801install.log". Feel free to use a different path if that is appropriate. The log file will be useful if the /reinstall flag doesn't fix the problem you are facing.

Please post your results

Thanks

Using the \reinstall switch worked just great.   Thanks a lot
