Measurement Studio 8.6 Install Error

[jrolston]

Hi, I'm getting an "Unknown Error" when trying to upgrade from Measurement Studio 8.5 to 8.6, which causes the install to fail.  I tried uninstalling all NI products, but this didn't help (error persists).  I'm using Visual Studio 2008 and 2005 (2005 since I needed Measurement Studio ActiveX controls in my projects, and was told this was the only way to do it: http://forums.ni.com/ni/board/message?board.id=232&message.id=7393#M7393).  Any one have any ideas?

I've made some progress by trying several things.  

1) I uninstalled/reinstalled Visual Studio.  This had no effect

2) I uninstalled every file on my computer relating to National Instruments or Measurement Studio (on top of the normal uninstall routines).  No effect.

3) I ran CCleaner (a registry cleaner).  No effect.

4) I scoured the registry free of everything containing "measurement studio" with regedit.  This fixed the "unknown error" error.  The software is now installing, and I'll send an update if/when it completes.

Nope.  A new "Unknown error" occured upon installing the NI-DAQ device drivers.  So, I again went through the registry and removed everything related to "measurement studio" and "national instruments", with the exception of keys relating to examples.  There were hundreds upon hundreds of these.  So many that I couldn't use regedit to search, or else I'd spend my entire life finding and deleting these entries.  I instead downloaded Registrar Registry Manager, which lists all matches to a particular search and delete them.  However, it doesn't delete the entry, just the data.  So I used Registrar to find all non-example keys, and then regedit to delete them.  Took a looong time.

When this was done, I ran the device drivers installer, and the unknown error was not present.  So I stopped that install and started the measurement studio install from scratch.  MStudio installed fine, but again the device drivers had an unknown error. 

Still didn't work.

So, I again went back to the registry and removed any mention of National Instuments or Measurement Studio or "nidaq".  This appears to have done the trick.  Both MStudio and the device drivers are installing without "unknown errors".
