I have been a DataEase user since 1982, when it was called DataMaster, and am directly responsible for at least 9 other businesses purchasing the application through me. 

I have been retired for over 20 years and now use my DE application only for me to manage my investments, updating my current database regularly and deleting data for those sold. I have not needed to go into developer mode to change applications for more than 10 years. I bought a new PC last April and a new laptop in January, installed Dataease without problem, and updated my data successfully on December 31st. I used the application without difficulty during January.

Over this last weekend, I tried to update the data. I have been trying to log in to the application several times on both machines, but have been unable to do so. DataEase opens and shows the application list. As soon as I click the application (it is now the only one in the list), it "hangs" on the next page after I enter the username and won't accept the password. 

I then had a brainwave and tried again on my old laptop, which hadn't been used since January. It has not had any updates since then, and I was going to wipe all my data on it and do a factory reset of the HD this Easter weekend. Fortunately, I didn't do this earlier as I have managed to get into my DataEase application a few times since Sunday, but this has been intermittent.

Can someone please explain to me what has happened? I have noted that there has been some Forum activity about a similar problem with a later version of DataEase, and solutions have been offered. Can I have the same, please?

Long time since anyone around here has started DataEase 7(2) sow as a little weird to try it, and it was hanging for quite a while (compared to LE9/DE9) before starting up.

If memory doesn't fail me, DE7 do a big NETBIOS search to find other DE users before opening up an app and that way of looking up network user is obsolete so it fails before it open the app (this was removed early on in DE8). 

There is nothing that has happend with DE7 but obviously it will get more and more obsolete as times pass. Possibly MS have done something that DE7 doesn't agree with.

You can try to re-install it to see if it helps as MS do a lot of deleting and it might also be an update to your antivirus software that block some files.

Thank you for your prompt reply.

I had considered all the ideas you suggested before sending in my query. However, my version of Dataease was a slightly earlier version than the one you sent the link to, so I uninstalled my version, ran an app that wiped all vestiges, and then used the link you sent to install the later version. This worked, and I was able to open my application. I spent as much time as I could copying data into Word and Excel files last night, just in case I lost access again. I also closed and reopened DataEase three times, without any problem. 

I tried to open Dataease again this morning, without success. I repeated what I did yesterday, again without success this time. However, I read later this morning that last Friday's and Tuesday's MS Windows 11 updates were flawed, causing some applications to fail to open. As instructed, I updated Windows with yesterday's W11 update, then repeated yesterday's reinstallation of Dataease. Again, it has failed. It hangs when I get to the username and password entry. I tried to open Club Paradease from the samples, with the same outcome.

I have checked that the database hasn't moved:

As you can see, the relevant files were last used at 23.10 last night. What I can do this morning is create a new application that opens in Designer mode (see attached file). 

So, is there anything else I can do? Thankfully, I can now view all my historical data, but I can't update it. 

Our guess is that your virus software has blocked some of the files in DataEase 7.

Check your virus software/firewall etc. 

In Windows 11 there is also a Smart App Control which is very invasive. It is there to protect yourself from yourself.

Its a DNA feature in WIndows 11 and can only be enabled from a clean install of WIndows 11 and if switched off it can never be enabled again as your OS then already might be "infected". 

I don't think this is Smart App Control but rather your anti-virus that is "hyper active".

As long as you have your app you don't loose anything. 

Download LE9 from here, you should be able to migrate the app quite easily and see if you get the same problem.

You get 30 days trial so can use it to see what the problem is.

Hi All! https://www.dataease.com/static/files/DataEase-7.2.3.947.exe  What serial # needed to test ? Glory to DataEase Team!

There  is no trial or testing serial for 7.2. Its just a legacy download.

Thx a lot for Your reply! 

Thank you for your suggestions. I tried all of them, except trialling DataEase 9x, without success. At this stage of my later years of age, I did not want to move to a new platform. 

However, I did learn that MS had fouled up their updates yet again last Friday. My problem only started after I accessed DE7 following that update, and it continued after the first "emergency update" released by MS on Tuesday, which I had installed. When I learnt of another "emergency update" on Thursday, I waited until I could install this and then once that was completed, I tried to open my DE program again - and it worked the first time".

Since then, during the following 36 hours, I have rebooted my PC a couple of times and opened my DE7 files again, without a problem.

The sloppiness of Microsoft has yet again wasted a lot of my time - and, of course, those of you on this Forum also. Sorry.

don’t worry … simply keep in mind and take that story about CP/M and IBM and OS for the first IBM PC  into account… Glory to DataEase team nevertheless !
