I've been using VIPM for years to access the LabVIEW Tools Network. Recently, one of my machines was set up with a User Account (where I do most of my work) and a separate Admin account. A while ago, I tried to install EasyXML and got a strange error (among other things, I was told the package was not compatible with my OS nor any version of LabVIEW installed on my computer). Turns out the "fix" was to run VIPM from my Admin account.
But do I learn? No, months later, I try to install another package. Similar error. While browsing this Forum, I run across my previous note and see "Run VIPM as Administrator", which (are you surprised?) fixes this "new" error. You'd think I would have learned my lesson, but I can at least pass on this warning.
