One would have an idea of what could do the following behavior in a Dataflex VDF 6.2 installation and Crystal Reports 7.0 (same old) on a windows 10 machine Home 64-bit:
1) On just one system, reports run seamlessly in both the Crystal Designer and the Dataflex system.
2) On all other systems, reports run seamlessly in Crystal Designer, but on all other systems if you run the report on the dataflex system it opens and gives the message that it can not access the file, and it gives database error DLL.

As the Crystal Reports installer does not run on windows 10 - it gives the message that this application can not run on this machine - the installation was manual - with copies and records of the files in Crystal. But in this case there is no definition of the dataflex systems directory, only Crystal.

if anyone has an idea I can share, thank you in advance
