Windows 10 64b and Five-xHarbour-32 b programs

[FranciscoA]

Greetings to all.
I decided to expose this case, looking for any same or similar experience, so some of you have passed, and they can share to find a solution.

about 10 years ago I developed a program FiveVin-xHarbour Accounting with 32 bits, on which I never had any customer information about a problem in performance. When I installed the software, the customer had computers with Windows XP operating sistem.

In past days he called, and I find out that less than a year ago he had changed all computers (4), for ones new with Windows 10 64-bit processors i3, 4g ram. It mean, the same hardware and operating system (Win-10 64B). The software was installed in one of them, which give use as a "dedicated server".

The problem is that access to dbf from other cpu is painfully slow ( "slower than a turtle going backward"), when more than 1 user connects to the program.

The technician who maintains them, and who installed Windows 10 64b them, has been unable to resolve and argues that it is because the program is 32 b.

Some of you have been through this? It has found a solution?

Thanks for your comments and answers-
