Maybe someone else could see already what is happening, but I have some questions now. I see windows 7. Is it 32 bits or 64 bits? And you said you installed Toad 11? Are you sure?

Aaargghhh. Bert, don’t remind me of “a valid and in force maintenance contract”, please? Something went wrong somewhere and we have no maintenance contract anymore. And I noticed this just when I tried to download version 11 GA. Sigh. But I already contacted someone here in Holland to solve the problem… Groetjes, Wim 2011/9/28 Bert Scalzo ``` Did you download the update from support.quest.com – which requires a valid and in force maintenance contract?

If you are not on maintenance (as you say) and thus cannot log in to our support site – then you cannot legally get a copy of toad that will work with a license key – period. If you try to install the trial and enter a commercial non-trial key it will give an access violation. That’s the first question that needs asked when a simple upgrade does not work. If you’re not on maintenance then you cannot upgrade. So since you say you are not on maintenance, then there is zero reason to download and install toad since it won’t work. ---

Yes sir, I know sir, I apologize sir. I’m working currently with trial 11.0.0.103 which expires on 30 September and switch back to 10 until the maintenance contract problem is solved.

Not trying to be a bum on this – just making sure was all …. The betas usually check for the most recent version of toad. So you won’t be able to use the beta unless you’re on toad 11. This is not done to annoy you – but rather not to have bug reports and new feature requests that already have been addressed – which our few developers simply don’t have to handle. ---

Apologies – John just read me the email in the true spirit it was intended – i.e. somehow our maintenance lapsed and we’re working on getting it back. I simply read it the other way.

Close… I did recall it from a movie… not the one you mentioned though (or was that a tv series you mentioned?). I don’t recall much, just a scene where a guy gets hit, says the “may I have another” line, gets hit again and says he was just kidding. Think it might have been Blade: Trinity.

Our licenses were purchased in the last 5 months and are still valid. The weird thing is Toad for Data Analysts works ok, but not the TOAD for Oracle. I initally had Toad for Oracle10.6 installed, but since last week, installed the Toad for Oracle 11. I am seeing similar issues on the new installation also. Your help will be much appreciated. I have been using SQL Developer/Toad for Data Analysts to get by, but really need Toad for Oracle to work. Thanks. ---

Did you do a clean install or import your old user files? If you imported, it’s possible something got corrupted in the conversion since going from 9.1 to 10.6 is skipping 6 versions. Try deleting the user files directory and starting with a clean install. Greg ---

That’s the correct spot. If you’re trying to start Toad 11, there should be a folder named Toad 11. Just delete that one and try restarting Toad. Greg ---
