Does the same happen if you right-click the file (first Studio, then MultiTerm) and chose "Run as administrator"?

Hi there, thank you for replying.  I just checked that now and yes the same happens there as well.

I tried step 3. It made no difference to the message I get saying this app can't run .... I am unwilling as I said to risk my computer's security and this should not be happening at all.  

Slightly unnrelated to this is an email I got a while ago from SDL saying I earned a level 3 achievement but all I have done is ask a question, not answer someone else's.  This is bizarre but the issue at hand is more important. thanks.

Hello Anne M Corbett

This is not a Studio related issue as other customers can install it without any issues. This rarely happens and when it does it`s due to antivirus or some settings on your operating system that are preventing application to install. If you are not willing to try all my suggestions I would recommend to contact Microsoft as they should know more about this kind of issues.

Thank you,

OK it is not that I am unwilling as such but unwilling to risk my computer's security.  I agree that is probably not SDL issue. Definitely windows 10 I think.  I will get onto microsoft about it.  I have tried the compatibility troubleshooter but it is not letting me 'test the program' at a certain stage of the process.   Very wierd.  Thanks for trying anyway.  I may turn off the antivirus later on if I really have to, but for now I am not sure I should.

If I may ask one more question for the time being.  Should I keep those two .exe files - Studio and Multiterm - on my desktop until I do take action or should I delete them and try to download them again later? If that's even allowed.

Hello Anne M Corbett

The installers you have are for the latest versions of Studio and Multiterm but you can delete them and download them again to make sure it`s not a problem with them. 

Try to save them in another location then your desktop and try to run them as admin to see if it works.

Thank you,

Sorin

ok thanks I'll try that.   And just in case this counts, how many versions of SDL trados can you have on your computer at one time?  

Hello Anne M Corbett

You can install all the version at the same time but you can activate them only if you have a license for each version.

In your case you can install Studio 2019 and activate it with your 2019 license and you can also use Studio 2017 as described in this article: https://gateway.sdl.com/apex/communityknowledge?articleName=000007709

Thank you,

Sorin

that's great thanks.  I wasn't sure. 

Believe it or not I just downloaded them again after deleting the ones I downloaded the other day (Tuesday actually) and they seem to be installing now. I saved them to a specific folder on my desktop rather than the desktop itself. 

The .exe files are in the folder mentioned but the two now installed programs (Trados and multiterm) are seen on the desktop.

I did get a message up titled 'Chainer' saying 'There is already an instance of this program. This instance will exit' just as the installation was kicking off on Trados.  I said yes to that assuming it was safe and it does not seem to have interfered with the installation of either.   That's great.  I did not have to disable the antivirus or anything.  Just to let you know and anyone reading this who may have the same issue in the near future.
