Windows is fun isnt it?
How about if you double click on the Rave (Discovery II _ Freelander '01)\Acrobat4\Reader\AcroRd32.exe ?
Does it open the Adobe Acrobat 4.0 Reader OK?
Did you try clicking the 'change settings for all users' and changing the compatibility and run as admin settings, in case something is funny there?
EDIT: Actually - since I had previously run the troubleshooter (why I know not) in the 'for all users' settings it was compatibility for XP, which dont work), so praps a possibility?
Have you completely rebooted?
I am not sure about this, but I have fast boot disabled in the BIOS as I have a dual boot Win 10 and Linux on the same lappy
I think this means that windows completely reboots now, rather than doing a halfway housesort of thing to speed up windows boot (like trying to improve the 0-60 time of my old Allegro estate LOL)
Actually it was to try to stop people dual-booting but they failed.
Again - I am not sure here but it might be worth a try
Entering into your BIOS is by pressing a key depending on the computer Manufacturer (on my ASUS it F2 I think) during boot and then just changing the option
Another possible approach ....
Win 10
I have RAVE installed on my Windows 10 (that I never use), and this has loads of other programs (sorry, we must say 'apps' these days
) installed and is an 'old installation of Windows.
On this Windows 10, when I open RAVE it gives me 7 pop up windows on the trot saying that, 'There was an error opening this document. The path [sometimes it says 'files'] does not exist' which when I click on 'OK' they disappear and after the last one I am good to go.
VM Win 10 in Linux
On my Win 10 inside a Virtual Machine in Linux is a new installation with almost nothing there - I only use it as to write Journal papers I need M$ Office as some co-authors and Journal require it
In this instance of Win10, RAVE opens without any of those error pop-ups at all
I have no idea why, nor what the files it cant find are
But, perhaps you could try cleaning your registry with
CCleaner free version?
I have used it for years with no problems, and it may or may not help (and even speed up your windows a bit)
Its pretty bulletproof, nothing like delving into the registry manually
Another thing is what else from adobe do you have installed on your computer?
I have Adobe Reader DC on the Win10 and nothing from ADOBE on the VM Win 10
And of course, you could follow all those M$ 'helpers' that tell you to run all the neverendingcircularwildgoosechase troubleshooters or to do a completely new installation of win10.
Probably wouldnt work tho! LOL
