I can't even begin to explain how happy I am that we recently released the Office 2003 PIA download. Why am I excited? Just read this and you will understand. I've known about this for a while but I had to keep my mouth shut :-).
Not being able to install the PIAs is the single biggest deployment issue I've had with my Send to OneNote from Outlook PowerToy. I have about 10 emails in my inbox from users who could not install it and up till now I had nothing really to tell them except "sorry".
Well, I plan on releasing a new version of Send to OneNote from Outlook that includes the redistributable, as well as a few dozen bug fixes and minor features.
I really appreciate the work that the office folks did in releasing this. They listened to me yell and scream for a few months about this problem, and they fixed it. Thanks guys!
