Need help with illogical issue

[Kicker]

background:

• I have created multiple Access databases for a local hobby club.
• There are thousands of lines of VBA code
• These programs are individually installed on 10 computers and have been working perfectly for several years.
• They are written in MS Access 365
• Each computer is a 64-bit system running Windows 10

Issue:

• We just added a new computer to the mix.
• It has a 64-bit process
• It is running Windows 10
• Non of the applications will run

Error Message:

• There is no error message number
• The message box tells me to "update the program to run on a 64-bit processor"

We have looked for and tried several things, but to no success.

Any ideas what I can try? Any ideas 'why' this is happening?

kicker, have we spoken before, your id seems familiar?
Does Access run?
Do any databases open?
Can you create a new database that works?
Can you import the objects from the problem databases in to a new database?

I am going to bed now as it is 23.46 here in the UK, so I will talk to you tomorrow.

Yes I believe we have spoken before. I'm going to mark this solved because I found the problem which I hate to admit.
We've been working with Office 365 - Access. Everything has been working great until we bought a new computer. Office 365 was installed as 64-bit. I discovered that the other installations were 32-bit. The VBA had some declare statements only valid in 32-bit.

Fixed the code and it works.

Thanks
