Dear,
I have been using fivewin 32 bit version for ten years, I would like to switch to 64 bit version. Is it enough to buy 64 bit upgrade or do I have to buy installation package for 64 bit version.
Greetings

Please email me to alinares@fivetechsoft.com or to antonio.fivetech@gmail.com

thanks!

Dear Antonio,
Is there a step-by-step for to do this upgrade?

Dear Vilian,

There is no need for such step by step documentation as the migration to FWH 64 bits is quite straightforward.

If you use a resources DLL in 32 bits, then you have to migrate it to 64 bits. FWH provides a FWH\DLL\rc2dll64.bat for such purpose.

If you are using a library when building your EXE, then you have to get the equivalent 64 bits library version.

If you are using any C language developed keep in mind that the handles in Windows API must be managed using hb_parnll() and the returned handles must use hb_retnll(). Please notice the double LL.

Keeping in mind the above topics, it is a simple as using the FWH 64 bits libraries and recompile all your PRGs using the Harbour 64 bits version for your chosen 64 bits C compiler.

Thank you Master for your tips. I'll try it

I wonder for those using Fastreport, any of them migrated to 64-bit or not and if they did what was the solution?
