Encrypted hard drive that I can no longer access on Windows 10

I have an external hard drive that I had to encrypt when using on a work computer. It's protected with a password and to access files, I run unlock.exe and type in a password.
However, since upgrading to Windows 10, I can no longer access the files. When I run unlock.exe an error comes up saying "this app cannot run on your PC". I've tried compatibility troubleshooting and searched forums etc for a solution, but can't find anything.

Can someone help?!

I guess, from the limited information that you provide, that you are using the Smartware software from WDC. The latest version that I find is here:

WD Product Update

It's not listed for Windows 10, but it includes WIndows 8, so it will probably support 10 as well.

The manual for it is here:

Does your employer have any IT staff that could assist you with it?

Hello Katiej, and welcome to Ten Forums. :)

What did you use to encrypt the hard drive with?

If you used BitLocker, then you might see if you can use either tutorial below to unlock or recover the hard drive with the Bitlocker password or recovery key.

BitLocker Recovery - Unlock a Drive in Windows 8

BitLocker Repair Tool - Recover Drive in Windows 7 and 8

Thanks for the welcome :)
I can't remember what tool I used to encrypt it unfortunately. I don't think it was bitlocker as I've attempted the fixes and they haven't worked. Appreciate you trying to help though.

I don't work for that company any more which is part of the problem. I'll take a look at WDC. It sounds like it could be right. I am almost thinking I might have to find someone running Windows 8 or lower still and access it through their computer to remover the password.
