HELP,I can't reinstall my LabWindows/CVI

[yilu]

yesterday I found my LabWindows/CVI didn't work well,so I decided to reinstall it.

I directly deleted some of the programme folders , not via the control panel  of windows OS.

today I tried to reinstall my LabWindows/CVI. when I opened the item Nationa Instrument Software

 on the control panel  of windows  OS ,I found it didn't work too,because some of its files

were deleted by me yesterday as well. As  a result ,I can't reinstall LabWindows/CVI now,

the install process says Labwindows/CVI has already existed in my computer! !you know

what exist in my computer are only some wastes of the files .What can i do?Does anybody know

how to uninstall the former products thoriughly? Thanks very much!!!

Did you allready try a repair installation ?

The National Instrument Software button  on  Windows control panel has disappeared.

I don't know how to run a repair installation on this condition. Thanks for your help.

You need to get a tool called MSIBlast.  It should be found somewhere on this forum.  This will allow you to remove all the entries and remove any leftover files from your machine.  Then you can reinstall clean.

If you have trouble finding this application please let me know and I will repost it.
