It is a riddle, wrapped in a mystery, inside an enigma; but perhaps there is a key.
That quote by Winston Churchill always comes to mind for some reason whenever anything .Net Framework comes into play
Let's look for some
keys..... I have used TT for many years... Forgive my ignorance, (I've only used the online version myself) but is this something you need to buy a new version of every year? Every 2 years? Did you use, or try to use this version prior to this year? The reason I ask is prior to to the 2009 version only .Net Framework 2.0 was required and if this is the first time you're using a version requiring 3.5, we can reasonably assume the problem is with .Net 3.5
....That's when I encountered the problem. That's where you need to be more specific. What EXACTLY did the error message say? Were there any error codes given? If so, what were they/it? I see two messages similar to what you posted:
"TurboTax
engine has encountered a problem and must close"
"TurboTax
installer has encountered a problem and needs to close--EventType: clr20r3 (or similar)"
These 2 errors while similar offer different solutions. You must give the
PRECISE message and/or codes.
I can't emphasize this enough....At one point, I tried to reinstall the .netframework, but I honestly don't know what the heck I ended up doing. That's not good. Try keeping a log and recording EXACTLY what steps you're taking.
....If I look in Add Remove Programs, I have: Microsoft .Net framework 2.0 SP2, 3.0 SP2, 3.5 SP1, 4 Client Profile, and 4 Extended. Is that bad?? No and yes. It's not bad if you have programs that need them--
which you have--and it's not bad if you have all the security patchesfor them--which you say you have--
but it's bad if one of them is "broken"---which you apparently have. Argghhh! This is so aggravating - I really don't know what I am doing.That makes two of us then I share your frustration.
Edit to add: What Anti-virus are you using & did you ever use any McAffee or Norton AV? Are you using a 3rd party firewall?
