Installation may be corrupt -- LV 2011 SP1

[Nikolaus]

Our lab has been running LabView 8.5.1 for quite sometime and the installation just recently broke. On every account except the administrator I have been getting an "installation may be corrupt error". I figured this was going to be a confusing problem, so I decided it was a good time to upgrade. I uninstalled the 8.5.1 packages, and reinstalled with our new copy of LB 2011 SP1. Much to my dismay, I see the same behavior.

I don't really expect anyone to have the exact solution to this problem, but maybe someone can point me in the right direction. I did recently make a number of changes to the computer. I installed a few other programming packaes, such as MSVC++ and Basic Express Edition 2008, SQL Server 2008, Python 2.7.3 and a number of packages, and (embarassingly) XP SP3.

Obviously, I created a conflict somewhere, or possibly changed some permissions. But where....

I have uninstalled SQL Server 2008 (I never actually use it) and a seeminly redundant version of MS Visual Studio C++ Redistributable. I rebooted, and had the same problem. I tried a repair install, and had the same problem. Still no luck opening Labview from anywhere but the Administrator account. 

This doesn't even generate an error message.  All I get is the cryptic "installation may be corrupt..." message from Windows. This happens when opening from the start menu, or labview.exe.

For some reason no account had access to MSVCP71.dll

Thanks Ubuntu Live CD. Sorry for crowdin this forum with my thinking-out-loud. Hopefully, this will help someone else someday. Looking for the .dll file with the weird permissions turned out to be a good place to start.
