It's not worth the effort and testing. People would only experience it once every 3-4 years, depending on when they get a new laptop. Must still shouldn't have to worry since other software would install that version of .NET already.
Plus, people don't bother to read error messages anyways. Another tool I created would create PDFs of the financials. The first section would be pulled from the EPM and the second would be a data dump of every transaction for each cost center. If the totals don't match to the dollar, the script would throw an error.
90% of the time, it was because the EPM data was being refreshed as it's scheduled to do so every half hour and takes 3-4 minutes. So I had the error message tell the person to just go take a quick break and come back. Still, people would email me saying they don't understand why they're getting the error and it would always be fixed if they just wait.
They opened up a MC by me about a year ago.
I was returning an item last weekend and the employee made a comment on how many times I've been there haha.
