Error message and program not installing


Recommended Posts

Hi all.  I am trying to install a program from Just Flight and have not had issues with it before, but I keep getting an error message from the Program Compatibility Assistant saying that the program may have not installed correctly.  In fact it did not do anything!  I have tried to find any clues to see how/if I can turn that wretched compatibility thing off, but so far, no luck.  Anyway ideas on how to proceed?

 

Thanks.

Hi Martin,

You should be able to right click the installer program and select the compatibility tab and run compatibility checker?

Which JF program was it?

Hi Joe. 

Sorry for the delay in getting back to you.  Things have been a bit hectic here.

I have done some investigating and it appears that the issue is the interaction between the pre-installed Windows Defender on Windows 10 (which is virtually impossible to uninstall on this version of Windows),and my favored Anti-Virus software (System Mechanic Pro).  Funnily enough, I took my PC in for a 1TB SSD C-Drive to replace the pre-installed smaller one.  Things were alright back then.  Since they have reinstalled the software on C-Drive, I am finding things seem to have changed slightly.  What is happening is that I can use System Mechanic, but if I turn it off to download something, Windows Defender turns on!  I have found that if I uninstall System Mechanic and then turn off Windows Defender, it stays off while I download.  So, this appears to be the solution for the moment, albeit an inconvenient one!

Thanks as always for your input.

Best wishes

Martin.

P.S.  Stay safe over there in the UK as I know that things are getting bad with regards to Covid.
